ABOUT RHYTHM BIOSCIENCES

Rhythm Biosciences is committed to saving lives through  
early detection of cancers using simple and accurate 
diagnostic technology, providing physicians with accurate  
and reliable diagnostic tools.

Rhythm’s ColoSTAT® kit is a simple, affordable blood test  
for the early detection of colorectal cancer for global  
mass-market screening.

Colorectal cancer (CRC) is curable if detected early, 
and is the second leading cause of cancer death 
globally.1  In 2020, there were more than 1.9 million 
people diagnosed with CRC and over 930,000 
lives lost to the disease. 2 Europe, Australia and New 
Zealand (NZ) had the highest incidence rates. 2 By 
2040, the burden of CRC is predicted to increase  
to 3.2 million new cases (an increase of 63%) and  
1.6 million deaths (an increase of 73%) per year. 2  

2020 - 2021 National Bowel Cancer Screening 
Program report, identified that 6.7 million were 
invited to take the FIT test, 2.4 million people  
(37.4% of eligible participants) completed the test, 
and 1.2 million people (18.6% of eligible participants) 
were valid screening tests. 3  One of the reasons for 
the invalidity rate (50.3% of all completed tests) is 
due to tests being “spoilt” in the slow postal services 
before the pathology lab can analyse them.5  

Even though many countries around the world have 
implemented screening programs aimed at early 
detection (normally between 50 - 74 years of age), 
low participation and the increasing incidence rates 
are a significant challenge, particularly with younger 
people. 3 Australia and NZ data identifies that more 
than 11% of the people diagnosed with CRC, are 
below the age of 50. 3,4 Not only does this pose a 
public health challenge, it causes premature death 
and increased healthcare costs.1 In addition, more 
than 50% of people diagnosed with CRC in the 
United Kingdom (UK) and Australia are outside the 
current screening programs. 3,5,6

Faecal immunochemical test (FIT) is the prevalent 
CRC screening method globally. Unfortunately, 
the utilisation of the FIT test is low, due to 
inconvenience, cultural & religious beliefs, the “Yuk” 
factor, and / or physical inability to perform the test 
correctly. 

One of the challenges with the current screening 
method is the rate of true valid results. The 
Australian Institute of Health and Welfare (AIHW) 

In an observational study, among 460 people in 
the US who were offered CRC testing, 93.5% of the 
participants opted for a blood-based test over FIT.7   
Convenience and ease of a blood draw were main 
reasons for their preference.6

Rhythm’s ColoSTAT® kit, is a simple, affordable, 
blood-based test, developed for the early detection 
of CRC. Since listing on the ASX, the Company has 
run a multi-year research and development program 
that has successfully delivered technical validation 
of the 5-biomarker immunoassay across Europe, 
New Zealand, and the UK. 

ColoSTAT® provides an alternative for those 
unwilling or unable to participate in current 
screening programs and may increase the 
participation rate in CRC testing. With the 
increased incidence of CRC in younger people, 
ColoSTAT® could be part of a routine health 
examination, that may improve early diagnosis and 
survival rates.

A MESSAGE FROM  
THE EXECUTIVE 
CHAIRMAN 
OTTO BUTTULA

Dear Fellow Shareholders,

On behalf of the Board, I am pleased to present 
Rhythm Biosciences’ 2023 Annual Report.  The last 
financial year was not without disappointment, with 
a significant decrease in our share price, following 
our March 2023 decision to withdraw the current 
ColoSTAT® application with the Therapeutic Goods 
Administration (TGA).  Despite this occurrence, 
we remain committed to resubmitting to the 
TGA in 2024.  In the interim, we are focussing on 
commercialising ColoSTAT® in geographies where 
we have regulatory approvals already in place.

Notwithstanding our share price decline, I 
personally believe that the Company remains 
in a better position today than what it was at this 
time last year.  We remain confident that over the 
next financial year, your Company will join other 
successful Australian biotechnology enterprises 
that have transitioned to commercial, revenue-
generating enterprises.

We remain driven by the beneficial impact that 
the ColoSTAT® blood test will be an alternative to 
cancer diagnostics in a real-world setting, given the 
challenges with the current screening methods.

Importantly, our mission does not stop there, over 
the past 12 months we have advanced our platform 

technologies into three other cancer targets, breast 
(Agilex), lung (Baker Medical Institute) and gastric 
(Nexomics, part of the Peter MacCallum Cancer 
Centre).  Once, we start building meaningful 
commercial revenues with ColoSTAT®, we will look 
to further expand our pipeline.

In line with our ambition to commercialise the 
business, our executive leadership team and 
Board has been refreshed with new appointments 
throughout the year, as part of the Company’s 
ongoing succession planning, and to ensure we 
have the right skills and experience for future 
growth.  At Board level, I am pleased to have 
welcomed Ms Sue MacLeman, who has assumed 
the position of Non-Executive, Deputy Chair, 
an important independent position given my 
own ongoing role as Executive Chair.  Sue brings 
a wealth of global bio-sector experience to 
complement the diverse skills and experience 
of our Board.  I also acknowledge the valuable 
contribution of Eduardo Vom, a founding influence 
and shareholder of Rhythm, who retired from the 
Board in November 2022.

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTEXECUTIVE CHAIRMAN’S REPORT Summary of Operations

The ColoSTAT® technology has renewed patents 
across 21 countries, and the Company continues to 
investigate further patents in the interest of market 
potential.  This secures Rhythm’s market entry 
strategy.

The Company continued to produce the 
ColoSTAT® kit across our partnered Contract 
Manufacturing Organisations (CMOs). The 
production involved generating reproducible and 
scalable outcomes across the validation batches. 

The ColoSTAT® prospective, cross-sectional, 
multi-centre clinical study (RHY001), evaluating the 
clinical performance of ColoSTAT® for the detection 
of 5 biomarkers associated with colorectal cancer, 
was presented at a poster presentation at ASCO 
(American Society of Clinical Oncology), in 
Chicago. The ColoSTAT® test demonstrated a 
sensitivity of 81% and specificity of 91%, compared 
to the gold standard, colonoscopy.1 

TGA Withdrawal

The withdrawal of the ColoSTAT® TGA application 
was disappointing. However, the Company is 
addressing the feedback provided by Australian 

Therapeutic Goods Administration (TGA) 
assessment and is preparing to submit a revised 
application incorporating additional requirements 
that will also satisfy the changes for the European In 
Vitro Diagnostic Medical Device (IVDR).

Recent publications by the Australian Institute of 
Health and Welfare (AIHW)2 identified over the 
past 2 years, the current screening participation 
rate (50 - 74 years) in Australia was at 40.9% (2.4 
million people). Alarmingly, of the 2.4 million people 
that sent in their FIT for analysis, over 50% of the 
tests were invalid. Of the 15,473 people diagnosed 
with bowel cancer in Australia, more than 50% were 
outside the screening population (~12% were under 
the aged of 50, and ~39% were above the screening 
age of 74.)2

Although market entry in Australia is delayed, 
Rhythm continues to identify opportunities to 
position ColoSTAT® in other regions where it is 
approved through increased market awareness and 
collaboration with local participants.

Technology Platform Expansion

UKCA Mark

Rhythm has partnered with Nexomics, at the 
Peter MacCallum Cancer Centre, to investigate its 
leading markers in gastric cancer. The Company 
is also collaborating with Agilex Biolabs for breast 
cancer and the Baker Institute for lung cancer.

The ColoSTAT® colorectal cancer detection product 
was granted UKCA (UK Conformity Assessment) 
mark, fully conforming with the European directives 
for IVD Medical Devices (98/79/EC) and the UKCA 
requirements.

Manufacturing

Rhythm continued ongoing confirmatory testing of 
its commercially manufactured ColoSTAT® test-kit 
with its global France-based manufacturer, Biotem. 
The Company has also run feasibility testing at a 
second facility in the USA, which has led to a pilot 
batch confirming consistent and reproducible 
results.

Quality and Regulatory

ISO Certification

The UKCA mark is the new UK product marking 
(post Brexit) that is required for certain products 
being placed on the market in Great Britain 
(England, Wales, and Scotland). It replaces most 
products that previously required only a CE mark.

UKCA marking represents that the manufacturer's 
product meets the essential requirements of the 
UK MDR 2002 and is a legal requirement to place 
a device on the market in Great Britain / United 
Kingdom.

UK Subsidiary

The Company maintained its certification to the 
International Standard for In-Vitro Diagnostics and 
Medical Devices (ISO13485:2016), passing an audit 
conducted by the British Standards Institution 
(BSI). This standard certifies Rhythm’s Quality 
Management System, a key indicator for the high 
standard the Company has set.

The Company established a 100% fully owned UK 
subsidiary, Rhythm Biosciences UK Limited.

Rhythm Biosciences UK Limited, was established 
in June 2023 to assist in the importation and 
distribution channels of ColoSTAT® into the UK and 
other parts of Europe.

New Zealand Regulatory Approval

Commercialisation

Rhythm successfully registered ColoSTAT® with the 
New Zealand national database of medical devices 
and expanded its international regulatory footprint.

MedSafe is the New Zealand Medicine and Medical 
Devices Safety Authority, which is a business 
unit of the Ministry of Health and is the authority 
responsible for the regulation of therapeutic 
products in New Zealand. As a manufacturer of 
ColoSTAT®, Rhythm has registered with Medsafe 
and listed ColoSTAT® to its Web Assisted 
Notification of Devices (WAND) database.

Commercially, Rhythm has signed a strategic 
partnership with LINK Medical Solution Ltd., for 
the market entry into the UK (England, Wales, 
Scotland). The Company remains in dialogue with 
several potential partners both domestically and 
globally. With a product like ColoSTAT® it is more 
important to select the most appropriate partner 
that will maximise shareholder value over the 
medium to long term.

Currently, in the UK more than 61% of all 
diagnosed bowel cancer cases are outside the 
screening population (60 - 74 years of age). This 
gives ColoSTAT®, a simple blood-based test, the 
opportunity to address the large unmet need 
outside of the UK screening population.

Corporate

During the year, the Company continued its prudent approach to capitalising the business appropriately. Further funds 
of $3.7M were raised via the exercise of options associated with the previous year’s Non-Renounceable Rights Issue 
(NRRI). In line with a goal to continue a capital-light model in our executive structure, Otto Buttula continues in the 
position of Executive Chairman, post the resignation of Glenn Gilbert as CEO/MD.

On behalf of the Board, I would like to acknowledge the devotion of the entire team at Rhythm who have worked tirelessly 
over the year to position the Company for commercial success over the next financial year. Our diligent and hardworking 
Board members have also made a strong contribution. Equally important, has been the support from our shareholders 
and business partners for which the Company is thankful. We look forward to developing the Company's global influence 
over financial and calendar year 2024, as we continue to pursue our purpose of helping patients screen for  cancers early, 
with a simple blood-based test. 2024 is shaping up to be our most important year yet and we expect to deliver positive 
news and re-build shareholder value in the near future.

Principal Activities 

Rhythm Biosciences Limited (ASX: RHY) is developing and commercialising Australian medical diagnostics technology 
for sale in domestic and international markets. Its ColoSTAT® product, which is nearing the commercialisation phase aims 
to provide an early detection test for colorectal cancer. 

Corporate Information

Rhythm, a company limited by shares, is incorporated and domiciled in Australia. Rhythm has prepared a consolidated 
financial report incorporating the entity that it controlled during the financial year.

The registered office and operations of the Company are located at Bio21 Institute, 30 Flemington Road, Parkville 
Victoria, Australia, 3010.

Results of Operations

The Group incurred a loss after income tax of $8,217,557 for the year ended 30 June 2023 (2022: $8,793,521).

The Executive Chairman’s Report contains a review of operations.

Significant Changes in the State of Affairs

There were no significant changes in the state of affairs of the consolidated entity during the financial year.

Future Developments

The Directors’ do not foresee any unusual future event that may significantly negatively impact the Group’s operations, 
results or state of affairs. 

Rhythm’s business model of developing diagnostic products for global markets will always bear some risk given the 
nature of technological development, competitors entering the market, changes in global healthcare, reliance on 
commercial partners and our ability to access capital to sustain operations. We cannot guarantee that Rhythm’s 
technology will be widely adopted. Moreover, the global healthcare industry is an ever-evolving landscape where 
changes may impact our business opportunities.

12

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTDIRECTORS' REPORTInternal Risks:
Most risks associated with personnel are limited due to the use of external consultants and outsourced agencies. 
Our people risks, were inherently our largest obstacle in the 2023 year which we have overcome with the training and 
diversification of knowledge. Cash Flow, is identified as a potential risk, despite minimising the exposure with the R&D 
grant and preparation of commercialisation. The management and Board have identified that Cash Flow is not expected 
to be an impediment to the commercialisation and growth of the company.

External Risks:
The major external risks are supply chain of raw materials and global demand.  With the current suppliers of raw materials and 
the proprietary recipe / algorithm, the raw material supply is adequate material for production for current and future target 
markets. It is anticipated that Rhythm will expand its CMO (Contract Manufacturers) globally as demand expands.

Dividends

No dividends were paid or declared since the start of the financial year. No recommendation for payment has been made.

The aim of the Company’s Remuneration Policy, is to align the interests of directors and employees with those of 
shareholders. To do this, Rhythm sets remuneration levels that attract and retain highly skilled and experienced directors 
and employees and motivates and rewards performance that advances the Company’s strategic goals. 

Remuneration Structure

The remuneration of Key Management Personnel and employees is structured in two parts:

•  Fixed remuneration, comprising: base salary, superannuation and other benefits in lieu of salary; and
•  Variable remuneration, may include: a short-term incentive bonus (cash) and a long-term incentive in the form of 

options under the ESOP.

The Company aims to set the level of fixed remuneration at market levels for comparable jobs, in similarly structured and 
sized companies in the industry in which the Company operates. No advice from a remuneration consultant was sought 
during the financial year.

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTDIRECTORS' REPORT 
Short-Term Incentive Plan (STIP)

The STIP provides an incentive to employees to achieve an annual cash bonus on the achievement of corporate goals 
set at the beginning of each calendar year. These corporate goals are clearly defined, drive shareholder value and can 
be objectively measured. The percentage of an employee’s base salary that can be earned through the STIP is set by the 
Board for management personnel. At the end of the calendar year the Board assesses the level of achievement of these 
corporate goals. Payments made pursuant to the STIP are at the discretion of the Board. 

Long-Term Incentive Plan (LTIP)

The purpose of the LTIP is to align the interests of directors, management personnel and employees with those of the 
shareholders and provide reward for sustained achievement of the Group’s strategic objectives. Rhythm’s LTIP  
is implemented through the Employee Share Option Plan (ESOP). 

Options

During the 2023 year, 10,950,000 (2022: 7,195,000) options were issued to management personnel and employees. 
The fair value of employee share options was $5,812,500 (2022: $6,258,750).  $3,003,935 was expensed in the current

Note 1: Statement of Significant Accounting 
Policies

The consolidated financial statements and notes represent 
those of Rhythm Biosciences Limited and Controlled 
Entities (the ‘consolidated entity’ or ‘Group’). The 
separate financial statements of the parent entity, Rhythm 
Biosciences Limited, have not been presented within this 
financial report as permitted by amendments made to 
the Corporations Act 2001. The financial report covers 
the economic entities of Rhythm Biosciences Limited and 
its controlled entities as an economic entity for the year 
ended 30 June 2023. Comparatives are disclosed for the 
year ended 30 June 2023.

The financial statements are presented in Australian 
dollars, which is the Group’s functional and presentation 
currency. The financial statements were authorised 
for issue on the date of the approval of the Directors’ 
declaration by the Directors of the Company.

Statement of Compliance

These financial statements are general purpose financial 
statements which have been prepared in accordance 
with the Corporations Act 2001, Australian Accounting 
Standards and Interpretations, and comply with other 
requirements of the law. The financial statements 
comprise the consolidated financial statements of the 
Group. For the purposes of preparing the consolidated 
financial statements, the Company is a for-profit entity. 
Compliance with Australian Accounting Standards 
ensures that the financial statements and notes of the 
company and the Group comply with International 
Financial Reporting Standards (‘IFRS’).

Basis of Preparation

Australian Accounting Standards set out accounting 
policies that the AASB has concluded would result 
in a financial report containing relevant and reliable 
information about transactions, events and conditions to 
which they apply. Material accounting policies adopted 
in the preparation of this financial report are presented 
below. They have been consistently applied unless 
otherwise stated.

The financial report has been prepared on an accruals 
basis and is based on historical costs, modified, where 
applicable, by the measurement at fair value of selected 
non-current assets, financial assets, and financial liabilities.

Going Concern

The consolidated entity incurred an operating loss of 
$8,217,557 (2022: $8,793,521) and had cash outflows from 
operating activities of $6,957,610 (2022: $6,496,402) for 
the year ended 30 June 2023. The consolidated entity is 
in start-up phase and does not yet have an income stream. 
These conditions indicate a material uncertainty that 
may cast significant doubt about the company’s ability to 
continue as a going concern.  The ability of the company 
to continue as a going concern is dependent on a number 
of factors, one being the continuation and availability of 
funds.

The financial statements have been prepared on a going 
concern basis, which contemplates the continuity of 
normal business activities and the realisation of assets 
and the settlement of liabilities in the normal course of 
business for the following reasons:

•  as at 30 June 2023, the consolidated entity had a cash 

position of $4.2 million;

•  a research and development refund, based on 

expenditure incurred, is expected in the second half of 
the 2023 calendar year;

•  activities are focused on commercialising ColoSTAT® in 
geographies where regulatory approvals are already in 
place, and the consolidated entity expects to generate 
revenue from this in the second half of the 2023 
calendar year;

•  the company has the potential to raise additional 

capital from investors; and

•  the consolidated entity is still in the early stages of 

operations and is able to scale back activity if required 
for cashflow management purposes.

Should the company be unable to continue as a going 
concern it may be required to realise its assets and 
discharge its liabilities other than in the normal course of 
business and at amounts different to those stated in the 
financial statements.

Accounting Policies

Principles of consolidation

The consolidated financial statements incorporate 
the assets and liabilities of all subsidiaries of Rhythm 
Biosciences Limited (‘company’ or ‘parent entity’) as at 30 
June 2023 and the results of all subsidiaries for the year 
then ended. 

Subsidiaries are all those entities over which the 
consolidated entity has control. The consolidated entity 
controls an entity when the consolidated entity is exposed 

28

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTFINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023 
 
 
to, or has rights to, variable returns from its involvement 
with the entity and has the ability to affect those returns 
through its power to direct the activities of the entity. 
Subsidiaries are fully consolidated from the date on which 
control is transferred to the consolidated entity. They are 
de-consolidated from the date that control ceases. 

Intercompany transactions, balances and unrealised gains 
on transactions between entities in the consolidated entity 
are eliminated. Unrealised losses are also eliminated unless 
the transaction provides evidence of the impairment of the 
asset transferred. Accounting policies of subsidiaries have 
been changed where necessary to ensure consistency 

with the policies adopted by the consolidated entity.

The acquisition of subsidiaries is accounted for using the 
acquisition method of accounting. A change in ownership 
interest, without the loss of control, is accounted for as 
an equity transaction, where the difference between the 
consideration transferred and the book value of the share 
of the non-controlling interest acquired is recognised 
directly in equity attributable to the parent.

Operating Segments

Operating segments are presented using the 
‘management approach’, where the information presented 
is on the same basis as the internal reports provided to the 
Chief Operating Decision Makers (‘CODM’). The CODM 
is responsible for the allocation of resources to operating 
segments and assessing their performance.

Revenue Recognition

Revenue is recognised at the fair value of the consideration 
received net of the amount of goods and services tax 
(GST) payable to the taxation authority. For each contract 
with a customer, the consolidated entity: identifies the 
contract with a customer; identifies the performance 
obligations in the contract; determines the transaction 
price which takes into account estimates of variable 
consideration and the time value of money; allocates 
the transaction price to the separate performance 
obligations on the basis of the relative stand-alone selling 
price of each distinct good or service to be delivered; 
and recognises revenue when or as each performance 
obligation is satisfied in a manner that depicts the transfer 
to the customer of the goods or services promised.

Interest income is recognised as it accrues, taking into 
account the effective yield on the financial asset.

Government stimulus and research and development tax 
refund Income Is recognised when there Is reasonable 
assurance that the eligibility conditions are met and that 
the grants will be received.

Income Tax

Income tax expense represents the sum of the tax 
currently payable and deferred tax.

Deferred tax is accounted for using the balance sheet 
liability method in respect of temporary differences arising 
between the tax bases of assets and liabilities and their 
carrying amounts in the financial statements. No deferred 
income tax will be recognised from the initial recognition of 
an asset or liability, excluding a business combination, where 
there is no effect on accounting or taxable profit or loss.

Deferred tax is calculated at the tax rates that are expected 
to apply in the period when the asset is realised or liability 
is settled. Deferred tax is credited in the income statement 
except where it relates to items that may be credited 
directly to equity, in which case the deferred tax is adjusted 
directly against equity.

Deferred income tax assets are recognised to the extent 
that it is probable that future tax profits will be available, 
against which deductible temporary differences can be 
utilised. No deferred tax assets have been recognised on 
the statement of financial position as at 30 June 2023, as 
the probability of deriving a benefit is uncertain. 

The amount of benefits brought to account or which may 
be realised in the future is based on the assumption that 
no adverse change will occur in income taxation legislation 
and the expectation that the Group will derive sufficient 
future assessable income to enable the benefit to be 
realised and comply with the conditions of deductibility 
imposed by the law. 

Current and Non-Current Classification

Assets and liabilities are presented in the statement of 
financial position based on current and non-current 
classification.

An asset is classified as current when: it is either expected 
to be realised or intended to be sold or consumed in the 
consolidated entity’s normal operating cycle; it is held 
primarily for the purpose of trading; it is expected to be 
realised within 12 months after the reporting period; or 
the asset is cash or cash equivalent unless restricted from 
being exchanged or used to settle a liability for at least 
12 months after the reporting period. All other assets are 
classified as non-current.

A liability is classified as current when: it is either expected 
to be settled in the consolidated entity’s normal operating 
cycle; it is held primarily for the purpose of trading; it is due 
to be settled within 12 months after the reporting period; 
or there is no unconditional right to defer the settlement of 

29

the liability for at least 12 months after the reporting period. 
All other liabilities are classified as non-current.

are determined after deducting rebates and discounts 
received or receivable.

Deferred tax assets and liabilities are always classified as 
non-current.

Cash and Cash Equivalents

Cash and cash equivalents includes cash on hand, 
deposits held at call with financial institutions, other short-
term, highly liquid investments with original maturities of 
three months or less that are readily convertible to known 
amounts of cash and which are subject to an insignificant 
risk of changes in value. For the statement of cash flows 
presentation purposes, cash and cash equivalents 
also includes bank overdrafts, which are shown within 
borrowings in current liabilities on the statement of 
financial position.

Trade and Other Receivables

Trade receivables are initially recognised at fair value 
and subsequently measured at amortised cost using 
the effective interest method, less any provision for 
impairment. Trade receivables are generally due for 
settlement within 30 days.

Collectability of trade receivables is reviewed on an 
ongoing basis. Debts which are known to be uncollectable 
are written off by reducing the carrying amount directly. A 
provision for estimated credit losses of trade receivables 
is raised when there is objective evidence that the 
consolidated entity will not be able to collect all amounts 
due according to the original terms of the receivables 
expected. Significant financial difficulties of the debtor, 
probability that the debtor will enter bankruptcy or 
financial reorganisation and default or delinquency in 
payments (more than 60 days overdue) are considered 
indicators that the trade receivable may be impaired. The 
amount of the impairment allowance is the difference 
between the asset’s carrying amount and the present 
value of estimated future cash flows, discounted at the 
original effective interest rate. Cash flows relating to 
short-term receivables are not discounted if the effect of 
discounting is immaterial.

Other receivables are recognised at amortised cost, less 
any provision for impairment.

Inventories

Raw materials, work in progress and finished goods are 
stated at the lower of cost and net realisable value on 
a ‘weighted average’ basis. Cost comprises of direct 
materials and delivery costs, direct labour, import 
duties and other taxes. Costs of purchased inventory 

Stock in transit is stated at the lower of cost and net 
realisable value. Cost comprises of purchase and delivery 
costs, net of rebates and discounts received or receivable.

Net realisable value is the estimated selling price in the 
ordinary course of business less the estimated costs of 
completion and the estimated costs necessary to make 
the sale.

Intangibles

Research and Development

Expenditure during the research phase of a project 
is recognised as an expense when incurred. Product 
development costs are capitalised only when each of the 
following specific criteria has been satisfied:

i.  Technical feasibility of completing development of 
the product and obtaining approval by regulatory 
authorities. 

ii.  Ability to secure a commercial partner for the product.

iii.  Availability of adequate technical, financial and other 
resources to complete development of the product, 
obtain regulatory approval and secure a commercial 
partner.

iv.  Reliable measurement of expenditure attributable to 

the product during its development.

v.  High probability of the product entering a major 

diagnostic market.

Capitalised development costs have a finite life and are 
amortised on a systematic basis over the period from when 
the product becomes available for use and ceases at the 
earlier of the date the asset is expected to exit the market 
or that the asset is classified as held for sale (or included 
in a disposal group that is classified as held for sale) in 
accordance with AASB 5.

Other Intangible Assets

Other intangible assets comprise licences and are stated at 
cost less accumulated amortisation and impairment losses.

Right-of-Use Assets

A right-of-use asset is recognised at the commencement 
date of a lease. The right-of-use asset is measured at cost, 
which comprises the initial amount of the lease liability, 
adjusted for, as applicable, any lease payments made at or 
before the commencement date net of any lease incentives 
received, any initial direct costs incurred, and, except where 

30

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTFINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023included in the cost of inventories, an estimate of costs 
expected to be incurred for dismantling and removing the 
underlying asset, and restoring the site or asset. 

The depreciation rates for each class of asset are:

Class of  
Non-Current Asset

Depreciation  
Rate

Estimated  
Useful Lives

Right-of-use assets are depreciated on a straight-line basis 
over the unexpired period of the lease or the estimated 
useful life of the asset, whichever is the shorter. Where the 
consolidated entity expects to obtain ownership of the 
leased asset at the end of the lease term, the depreciation 
is over its estimated useful life. Right-of use assets are 
subject to impairment or adjusted for any remeasurement 
of lease liabilities. 

The consolidated entity has elected not to recognise a 
right-of-use asset and corresponding lease liability for 
short-term leases with terms of 12 months or less and 
leases of low-value assets. Lease payments on these assets 
are expensed to profit or loss as incurred.

Property, Plant and Equipment

Each class of property, plant and equipment is carried at 
cost or fair value less, where applicable, any accumulated 
depreciation and impairment.

Plant & Equipment

The carrying amount of plant and equipment is reviewed 
annually by the Directors to ensure it is not in excess of the 
recoverable amount from these assets. The recoverable 
amount is assessed on the basis of the expected net cash 
flows that will be received from the assets’ employment 
and subsequent disposal. The expected net cash 
flows have been discounted to their present values in 
determining recoverable amounts.

Subsequent costs are included in the asset’s carrying 
amount or recognised as a separate asset, as appropriate, 
only when it is probable that future economic benefits 
associated with the item will flow to the Group and the cost 
of the item can be measured reliably. All other repairs and 
maintenance are charged to the income statement during 
the financial period in which they are incurred.

The assets’ residual values and useful lives are reviewed, and 
adjusted if appropriate, at each end of reporting period.

An asset’s carrying amount is written down immediately 
to its recoverable amount if the asset’s carrying amount is 
greater than its estimated recoverable amount.

Impairment of Non-Financial Assets

At each reporting date the Group reviews the carrying 
values of its tangible and intangible assets to determine 
whether there is any indication that those assets have 
been impaired. If such an indication exists, the recoverable 
amount of the asset, being the higher of the asset’s fair 
value less costs to sell and value in use, is compared to the 
asset’s carrying value. Any excess of the asset’s carrying 
value over its recoverable amount is expensed to the 
statement of comprehensive income.

Impairment testing is performed annually for intangible 
assets with indefinite lives and capitalised development 
costs not yet ready for use. 

Where it is not possible to estimate the recoverable 
amount of an individual asset, the Group estimates the 
recoverable amount of the cash-generating unit to which 
the asset belongs. 

Payables

Liabilities are recognised for amounts to be paid in the 
future for goods or services received. Due to their short-
term nature, they are measured at amortised cost and 
are not discounted. Trade accounts payable and other 
creditors are normally settled within 60 days.

Depreciation

Lease liabilities

The depreciable amount of all fixed assets, including 
building and capitalised lease assets but excluding freehold 
land, is depreciated on a straight-line basis over their useful 
lives to the Group commencing from the time the asset is 
held ready for use. Items of property, plant and equipment, 
are depreciated over their estimated useful lives.  

A lease liability is recognised at the commencement 
date of a lease. The lease liability is initially recognised 
at the present value of the lease payments to be made 
over the term of the lease, discounted using the interest 
rate implicit in the lease or, if that rate cannot be readily 
determined, the consolidated entity’s incremental 
borrowing rate. Lease payments comprise of fixed 
payments less any lease incentives receivable, variable 
lease payments that depend on an index or a rate, amounts 
expected to be paid under residual value guarantees, 

31

 
 
 
exercise price of a purchase option when the exercise 
of the option is reasonably certain to occur, and any 
anticipated termination penalties. The variable lease 
payments that do not depend on an index or a rate are 
expensed in the period in which they are incurred. 

yield and the risk free interest rate for the term of the 
option, together with non-vesting conditions that do not 
determine whether the consolidated entity receives the 
services that entitle the employees to receive payment. No 
account is taken of any other vesting conditions.

Lease liabilities are measured at amortised cost using 
the effective interest method. The carrying amounts are 
remeasured if there is a change in the following: future lease 
payments arising from a change in an index or a rate used; 
residual guarantee; lease term; certainty of a purchase 
option and termination penalties. When a lease liability is 
remeasured, an adjustment is made to the corresponding 
right-of use asset, or to profit or loss if the carrying amount 
of the right-of-use asset is fully written down.

The cost of equity-settled transactions are recognised as 
an expense with a corresponding increase in equity over 
the vesting period. The cumulative charge to profit or 
loss is calculated based on the grant date fair value of the 
award, the best estimate of the number of awards that are 
likely to vest and the expired portion of the vesting period. 
The amount recognised in profit or loss for the period is 
the cumulative amount calculated at each reporting date 
less amounts already recognised in previous periods.

Employee Entitlements

Short-term and long-term employee benefits

A liability is recognised for benefits accruing to employees 
for wages and salaries and annual leave in the year the 
related service is rendered.

Liabilities recognised in respect of short-term employee 
benefits are measured at their nominal values using the 
remuneration rate expected to apply at the time of settlement. 
Liabilities recognised in respect of long-term employee 
benefits are measured as the present value of the estimated 
future cash outflows to be made by the Group in respect of 
services provided by employees up to reporting date.

Contributions are made by the Group to employee 
superannuation funds and are charged as expenses  
when incurred.

Share-based compensation

Equity-settled and cash-settled share-based 
compensation benefits are provided to employees.

Equity-settled transactions are awards of shares, or 
options over shares, that are provided to employees in 
exchange for the rendering of services. Cash-settled 
transactions are awards of cash for the exchange of 
services, where the amount of cash is determined by 
reference to the share price.

The cost of cash-settled transactions is initially, and at each 
reporting date until vested, determined by applying either 
the Binomial or Black-Scholes option pricing model, taking 
into consideration the terms and conditions on which the 
award was granted. The cumulative charge to profit or loss 
until settlement of the liability is calculated as follows:

•  during the vesting period, the liability at each reporting 
date is the fair value of the award at that date multiplied 
by the expired portion of the vesting period.

•  from the end of the vesting period until settlement of 
the award, the liability is the full fair value of the liability 
at the reporting date.

All changes in the liability are recognised in profit or loss. 
The ultimate cost of cash-settled transactions is the cash 
paid to settle the liability.

Market conditions are taken into consideration in 
determining fair value. Therefore, any awards subject to 
market conditions are considered to vest irrespective 
of whether or not that market condition has been met, 
provided all other conditions are satisfied.

If equity-settled awards are modified, as a minimum 
an expense is recognised as if the modification has 
not been made. An additional expense is recognised, 
over the remaining vesting period, for any modification 
that increases the total fair value of the share-based 
compensation benefit as at the date of modification.

The cost of equity-settled transactions are measured 
at fair value on grant date. Fair value is independently 
determined using either the Binomial or Black-Scholes 
option pricing or models that takes into account the 
exercise price, the term of the option, the impact of 
dilution, the share price at grant date and expected price 
volatility of the underlying share, the expected dividend 

If the non-vesting condition is within the control of the 
consolidated entity or employee, the failure to satisfy 
the condition is treated as a cancellation. If the condition 
is not within the control of the consolidated entity or 
employee and is not satisfied during the vesting period, 
any remaining expense for the award is recognised over 
the remaining vesting period, unless the award is forfeited.

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTFINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023Issued Capital

Goods and Services Tax (‘GST’) and Other Similar Taxes

Ordinary shares are classified as equity. Incremental  
costs directly attributable to the issue of new shares or 
options are shown in equity as a deduction, net of tax,  
from the proceeds.

Financial Instruments

Recognition

Financial instruments are initially measured at fair value on 
transaction date, plus or minus transaction costs directly 
attributable to the acquisition. Subsequent to initial 
recognition these instruments are measured as set out below. 

Receivables 

Receivables are non-derivative financial assets with fixed 
or determinable payments that are not quoted in an active 
market and are stated at amortised cost using the effective 
interest rate method. 

Financial liabilities 

Non-derivative financial liabilities are recognised at 
amortised cost, comprising original debt less principal 
payments and amortisation. Lease liabilities have been 
recorded adopting an Incremental borrowing rate of  
4.99% (2022: 4.99%).

Impairment

An ‘expected credit loss’ (‘ECL’) model is used to recognise 
an allowance. Impairment is measured using a 12-month 
ECL method unless the credit risk on a financial instrument 
has increased significantly since initial recognition in which 
case the lifetime ECL method is adopted.

Earnings Per Share

Basic earnings per share is calculated by dividing the profit 
attributable to the owners of Rhythm Biosciences Limited, 
excluding any costs of servicing equity other than ordinary 
shares, by the weighted average number of ordinary shares 
outstanding during the financial year, adjusted for bonus 
elements in ordinary shares issued during the financial year.

Diluted earnings per share adjusts the figures used in the 
determination of basic earnings per share to take into 
account the after income tax effect of interest and other 
financing costs associated with dilutive potential ordinary 
shares and the weighted average number of shares 
assumed to have been issued for no consideration in 
relation to dilutive potential ordinary shares.

Revenues, expenses and assets are recognised net of 
the amount of associated GST, unless the GST incurred 
is not recoverable from the tax authority. In this case it is 
recognised as part of the cost of the acquisition of the 
asset or as part of the expense.

Receivables and payables are stated inclusive of the 
amount of GST receivable or payable. The net amount 
of GST recoverable from, or payable to, the tax authority 
is included in other receivables or other payables in the 
statement of financial position.

Cash flows are presented on a gross basis. The GST 
components of cash flows arising from investing or 
financing activities which are recoverable from, or payable 
to the tax authority, are presented as operating cash flows.

Commitments and contingencies are disclosed net of the 
amount of GST recoverable from, or payable to, the tax 
authority.

Comparative Figures 

When required by Accounting Standards, comparative 
figures have been adjusted to conform to changes in 
presentation for the current financial year. 

Critical Accounting Estimates and Judgments

The Directors evaluate estimates and judgments 
incorporated into the financial report based on historical 
knowledge and best available current information. 
Estimates assume a reasonable expectation of future 
events and are based on current trends and economic 
data, obtained both externally and within the Group.

Key Estimates

Share-based payments

Rhythm operates an Employee Share Option Plan 
(ESOP). The non-cash expense of issuing these options 
is calculated using a Black-Scholes option pricing model. 
This model requires the input of a number of variables 
including an estimate of future volatility and a risk-free 
interest rate. The probability of meeting any vesting 
conditions is also required to be estimated. Refer to Note 
17 to the financial statements. 

Research and Development Tax Refund Income

Research and development tax refund income Is 
recognised when there Is reasonable assurance that 
the eligibility conditions are met and that the grants 

33

will be received. Significant judgement is required in 
determining the income tax refund eligibility. There are 
many transactions and calculations undertaken during 
the ordinary course of business for which the ultimate tax 
determination is uncertain. 

Other Intangible Assets

Other intangible assets comprise licences and are stated 
at cost less accumulated amortisation. The consolidated 
entity assesses impairment of non-financial indefinite 
life intangible assets and intangible assets not yet ready 
for use at each reporting date by evaluating conditions 
specific to the consolidated entity and to the particular 
asset that may lead to impairment. If an impairment trigger 
exists, the recoverable amount of the asset is determined. 
This involves fair value less costs of disposal or value-
in-use calculations, which incorporate a number of key 
estimates and assumptions. 

Estimated Useful Lives of Other Intangible Assets

Rhythm determines the estimated useful lives and 
related amortisation charges for its finite life intangible 
assets. The useful lives could change significantly as a 
result of technical innovations or some other event. The 
amortisation charge will increase where the useful lives are 
less than previously estimated lives, or technically obsolete 
or non-strategic assets that have been abandoned or sold 
will be written off or written down. 

Provision for Impairment of Inventories

The provision for impairment of inventories assessment 
requires a degree of estimation and judgement. The 
level of the provision is assessed by taking into account 
expected future sales, the ageing of inventories and other 
factors that affect inventory obsolescence. 

Key Judgement 

Recognition of inventory raw materials 

The date of 3 November 2022 represents the time Rhythm 
commenced expenditure on acquiring ColoSTAT® 
inventory raw materials in preparation for commercial 
sales. Up until this date, costs incurred on raw materials for 
ColoSTAT® were expensed as research and development 
activities. Some items of previously expensed raw 
materials remain available for future commercial activities. 

Key milestones to a decision on commercialisation of 
ColoSTAT® and recognition of raw materials inventory 
included:

•  On 6 January 2022, Rhythm announced CE Mark 
registration in the United Kingdom, providing 
regulatory approval which allows ColoSTAT® to be sold 
in the respective UK regions. Further development of 
the product then continued to occur; and
•  On 3 November 2022, Rhythm announced the 

achievement of Medsafe approval in New Zealand 
which allowed a wider pathway to progressing pre-sales 
activities and partnership discussions.

Adoption of New and Revised Accounting Standards

During the current year, the Group has adopted all of the 
new and revised Australian Accounting Standards and 
Interpretations applicable to its operations which became 
mandatory.

New Accounting Standards for Application in Future 
Periods

The Board has assessed the impact of the new, but not 
yet mandatory, accounting standards issued by Australian 
Accounting Standards Board (AASB). The adoption of 
these Standards is not expected to have a material impact 
on the financial statements. The key Standard likely to have 
an impact Is set .

AASB 2021-2 (issued March 2021) Amendments 
to Australian Accounting Standards – Disclosure of 
Accounting Policies and Definition of Accounting 
Estimates (applicable from 1 July 2023)

Introduces a definition of ‘accounting estimate’, i.e. 
monetary amounts in financial statements that are subject 
to estimation uncertainty, such as estimating expected 
credit losses for receivables, or estimating the fair value 
of an item recognised in the financial statements at 
fair value. Accounting estimates are developed using 
measurement techniques and inputs. Measurement 
techniques comprise estimation techniques (such as 
used to determine expected credit losses or value in use) 
and valuation techniques (such as the income approach 
to determine fair value). The amendments clarify that a 
change in an estimate occurs when there is either a change 
in a measurement technique or a change in an input.

Ordinary shares

Ordinary shares entitle the holder to participate in dividends and the proceeds on the winding up of the company in 
proportion to the number of and amounts paid on the shares held. Ordinary shares have no par value and the company 
does not have a limited amount of authorised capital. On a show of hands every member present at a meeting in person 
or by proxy shall have one vote and upon a poll each share shall have one vote.

Capital risk management

The consolidated entity’s objectives when managing capital is to safeguard its ability to continue as a going concern, 
so that it can provide returns for shareholders and benefits for other stakeholders and to maintain an optimum capital 
structure to reduce the cost of capital.

Capital is regarded as total equity, as recognised in the statement of financial position, plus net debt. Net debt is 
calculated as total borrowings less cash and cash equivalents. In order to maintain or adjust the capital structure, the 
consolidated entity may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new 
shares or sell assets to reduce debt. The consolidated entity would look to raise capital when an opportunity to invest 
further into development and commercialisation or in a business seen as value adding relative to the current company’s 
share price at the time of the investment. The consolidated entity is not actively pursuing additional investments in the 
short term as it continues to integrate and grow its existing businesses in order to maximise synergies.

The capital risk management policy remains unchanged from 30 June 2022.

There are no impaired assets within trade and other receivables; these balances, and the balance of trade and other 
payables, are expected to be settled within 1 year.

Financial Assets Pledged as Collateral 

No financial assets have been pledged as security for any financial liability.

Financial Risk Management Policies

The Board are responsible for, among other issues, monitoring and managing financial risk exposures of the Group. The 
Board monitors the Group’s transactions and reviews the effectiveness of controls relating to credit risk, liquidity risk, and 
market risk. Discussions on monitoring and managing financial risk exposures are held regularly by the Board. The Board’s 
overall risk management strategy seeks to ensure that the Group meets its financial targets, while minimising potential 
adverse effects of cash flow shortfalls.

The Group did not have any derivative instruments at 30 June 2023.

Specific Financial Risk Exposures and Management

The main risk the Group is exposed to through its financial instruments is liquidity risk.

Credit Risk

Exposure to credit risk relating to financial assets arises from the potential non-performance by counterparties of 
contract obligations that could lead to a financial loss to the Group.

Credit risk is managed through maintaining procedures ensuring, to the extent possible, that members and 
counterparties to transactions are of sound credit worthiness. 

Credit risk exposures

Cash reserves form the majority of the Group’s financial assets. At 30 June 2023, cash was deposited with a large 
Australian bank in order to limit risk and ensure interest rate competitiveness. 

44

RHYTHM BIOSCIENCES   2023  ANNUAL REPORTFINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023Liquidity Risk

Liquidity risk arises from the possibility that the Group might encounter difficulty in settling its debts or otherwise 
meeting its obligations related to financial liabilities. The Group manages this risk through the following mechanisms:

•  preparing forward-looking cash flow analysis in relation to its operational, investing and financing activities; and
•  only investing surplus cash with major financial institutions.

Market Risk

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate as a result of 
changes in market interest rates. Exposure to interest rate risk arises on interest earned on cash and cash equivalents and 
term deposits.

The consolidated entity’s cash and cash equivalents and term deposits were $4,169,181 as at 30 June 2023 (2022: 
$7,595,424). An official increase/decrease in interest rates of 100 (2022: 100) basis points would have an adverse/
favourable effect on loss before tax of $41,692 (2022: $75,954) per annum. The percentage change is based on the 
expected volatility of interest rates using market data and analysts’ forecasts.

Price risk

Price risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate as a result of changes in 
market prices. The Group is not exposed to price risk.

Currency risk

Currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in 
foreign exchange rates. The Group’s exposure to currency risk is minimal at present as the majority of transactions are in 
Australian dollars.

Note 19: Segment Reporting

In accordance with Australian Accounting Standard AASB 8 Operating Segments, the Company has determined that it has 
one reporting segment, consistent with the manner in which the business is managed. This is the manner in which the chief 
operating  decision  maker  receives  information  for  the  purpose  of  resource  allocation  and  assessment  of  performance. 
The Group operates predominantly in one business and geographical segment being the research and development of 
biosciences in Victoria, Australia.

INDEPENDENT AUDITOR'S REPORT 

To the members of Rhythm Biosciences Limited 

Report on the Audit of the Financial Report 

Opinion  

We have audited the financial report of Rhythm Biosciences Limited (the Company) and its subsidiaries 
(the Group), which comprises the consolidated statement of financial position as at 30 June 2023, the 
consolidated statement of profit or loss and other comprehensive income, the consolidated statement 
of changes in equity and the consolidated statement of cash flows for the year then ended, and notes 
to the financial report, including a summary of significant accounting policies and the directors’ 
declaration. 

In our opinion the accompanying financial report of the Group, is in accordance with the Corporations 
Act 2001, including:  

(i)  Giving a true and fair view of the Group’s financial position as at 30 June 2023 and of its financial 

performance for the year ended on that date; and  

(ii)  Complying with Australian Accounting Standards and the Corporations Regulations 2001.  

Basis for opinion  

We conducted our audit in accordance with Australian Auditing Standards.  Our responsibilities under 
those standards are further described in the Auditor’s responsibilities for the audit of the Financial 
Report section of our report.  We are independent of the Group in accordance with the Corporations 
Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s 
APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) 
that are relevant to our audit of the financial report in Australia.  We have also fulfilled our other 
ethical responsibilities in accordance with the Code. 

We confirm that the independence declaration required by the Corporations Act 2001, which has been 
given to the directors of the Company, would be in the same terms if given to the directors as at the 
time of this auditor’s report. 

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis 
for our opinion.  

Material Uncertainty Related to Going Concern 

We draw attention to Note 1 in the financial report which describes the events and/or conditions which 
give rise to the existence of a material uncertainty that may cast significant doubt about the group’s 
ability to continue as a going concern and therefore the group may be unable to realise its assets and 
discharge its liabilities in the normal course of business. Our opinion is not modified in respect of this 
matter.

Key audit matters 

Key audit matters are those matters that, in our professional judgement, were of most significance in 
our audit of the financial report of the current period.  These matters were addressed in the context of 
our audit of the financial report as a whole, and in forming our opinion thereon, and we do not provide 
a separate opinion on these matters. In addition to the matter described in the Material uncertainty 
related to going concern section, we have determined the matters described below to be the key audit 
matters to be communicated in our report. 

Key audit matter  

How the matter was addressed in our audit 

Valuation of Inventory 

The Group recognised a material amount of inventory 
during the year representing raw materials purchased 
for the future production and commercial sale of its 
ColoSTAT product.   

Valuation of inventory including measuring raw 
materials at cost and assessing recoverability was 
considered a key audit matter due to the materiality 
of the recorded amount and the inherent subjectivity 
associated with valuation of inventory. 

Refer to Note 1 and Note 8 of the financial report for a 
description of the accounting policy and significant 
estimates and judgements applied to the recognition 
of inventory raw materials. 

Our procedures included, but were not limited to: 
•  Discussing procurement and inventory management 
processes with management and manufacturing 
partners. 

• 

•  Obtaining inventory confirmations from manufacturing 
partners and inspecting a sample of inventory items 
on a test basis. 
Examining supporting documentation, for a sample of 
inventory items, to test the inventory cost base and 
carrying values as of 30 June 2023. 
Examining evidence of commercial viability of future 
sales plans and future selling prices to assess 
recoverability of inventory. 

• 

•  Reviewing the adequacy of disclosures within the 

financial report. 

Research and Development Grant Revenue 
Recognition  

Our procedures included, but were not limited to: 
•  Updating our understanding of the revenue 

Other income includes a research and development 
(“R&D”) tax refund and Note 1 to the financial report 
discloses the accounting policy used by the Group for 
its recognition and measurement of its R&D tax refund 
revenue. 

Accuracy of the calculation of R&D claimed was 
considered a key audit matter due to the materiality 
of the recorded amount and the inherent subjectivity 
associated with the calculation of a R&D tax refund.  

Measurement of Share Based Payments  

A share-based payment expense was recognised for 
options that were granted in prior periods and 
continued to be expensed over their vesting period. 
Additional share options were expensed during the 
year relating to options issued during the 30 June 2023 
financial year to employees and key management 
personnel.

controls surrounding the recording of revenue. 
Engaging an auditor’s R&D tax expert to evaluate the 
assessment by management and management’s 
external expert of its allowable R&D expenditure 
claimed under Australian Tax Office rules.  

•  Vouching a sample of R&D expenditure claimed to 

underlying support documents. 

•  Checking the completeness and appropriateness of the 

disclosures included in the financial report. 

Our procedures included, but were not limited to: 
•  Reviewed board minutes and ASX announcements for 
the completeness of share-based payments issued 
during the period.  
Engaged an auditor’s valuation expert to calculate an 
appropriate valuation range for the new options 
issued during the period. 

• 

•  Reviewed all underlying agreements related to the 

issuance of any new share-based payments in addition 
to verifying whether there have been any

INDEPENDENT AUDITOR’S REPORT

Key audit matter  

How the matter was addressed in our audit 

Share-based payments are a complex accounting area, 
and due to this complexity and judgements used in 
determining the fair value of the share-based 
payments and the probability of vesting conditions 
being achieved, we consider the Group’s calculation of 
the share-based payment expense to be a key audit 
matter. 

• 

• 

Refer to Note 1 and Note 17 of the financial report for 
a description of the accounting policy and significant 
estimates and judgements applied to the share-based 
payment expense.   

modifications in the agreements in place from prior 
years. 
Evaluated the reasonableness of key estimates applied 
by management in determining the probability 
percentages of the various performance-based vesting 
conditions. 
Ensured that the recognition of the current year’s 
share-based payment expense and corresponding 
reserve balance movement were materially correct 
based on conditions stipulated within the underlying 
agreements. 

•  Reviewed the adequacy of the related disclosures 

within the financial report. 

Other information  

The directors are responsible for the other information.  The other information comprises the 
information in the Group’s annual report for the year ended 30 June 2023, but does not include the 
financial report and the auditor’s report thereon.  

Our opinion on the financial report does not cover the other information and we do not express any 
form of assurance conclusion thereon.  

In connection with our audit of the financial report, our responsibility is to read the other information 
and, in doing so, consider whether the other information is materially inconsistent with the financial 
report or our knowledge obtained in the audit or otherwise appears to be materially misstated.  

If, based on the work we have performed, we conclude that there is a material misstatement of this 
other information, we are required to report that fact.  We have nothing to report in this regard.  

Responsibilities of the directors for the Financial Report  

The directors of the Company are responsible for the preparation of the financial report that gives a 
true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 
and for such internal control as the directors determine is necessary to enable the preparation of the 
financial report that gives a true and fair view and is free from material misstatement, whether due to 
fraud or error. 

In preparing the financial report, the directors are responsible for assessing the ability of the group to 
continue as a going concern, disclosing, as applicable, matters related to going concern and using the 
going concern basis of accounting unless the directors either intend to liquidate the Group or to cease 
operations, or has no realistic alternative but to do so.  

Auditor’s responsibilities for the audit of the Financial Report  

Our objectives are to obtain reasonable assurance about whether the financial report as a whole is free 
from material misstatement, whether due to fraud or error, and to issue an auditor’s report that 
includes our opinion.  Reasonable assurance is a high level of assurance, but is not a guarantee that an 
audit conducted in accordance with the Australian Auditing Standards will always detect a material 
misstatement when it exists.  Misstatements can arise from fraud or error and are considered material 
if, individually or in the aggregate, they could reasonably be expected to influence the economic 
decisions of users taken on the basis of this financial report.
