An upcoming audit does not have to mean weeks of chasing documents, answering last-minute questions and discovering problems you did not know existed.

The businesses that experience the smoothest audits usually start preparing well before the auditor arrives.

Want expert help? Daintree Consulting's audit and assurance services can take this off your plate. Book a free consultation.

The key is not simply having your accounting records available. You need to be able to demonstrate where the numbers came from, how important transactions were recorded, what controls are in place and why management has made particular accounting decisions.

In Australia, the exact requirements depend on your entity, the purpose of the engagement and the applicable legislation or reporting framework. Certain companies are required to have financial reports audited, while other organisations may face audit or assurance requirements because of their structure, funding arrangements, trust obligations, contracts or regulatory requirements.

This practical checklist explains how to prepare for an audit in Australia, what documents to organise, which areas commonly create delays and how to make the process more efficient.

Quick Answer: How Do You Prepare for an Audit?

The best way to prepare for an audit is to get your financial records, reconciliations, supporting documents and internal controls organised before the formal audit begins.

A practical audit preparation checklist includes:

1. Confirm the purpose and scope of the audit.

2. Understand the reporting period and key deadlines.

3. Make sure your bookkeeping is complete and reconciled.

4. Prepare financial statements and supporting schedules.

5. Gather bank, loan, payroll, tax and asset records.

6. Review major transactions and unusual movements.

7. Document important accounting judgements and estimates.

8. Check internal controls and approval processes.

9. Prepare a clear evidence folder or data room.

10. Nominate one person to coordinate auditor requests.

11. Respond to questions with complete supporting evidence.

12. Resolve known issues before the audit starts where possible.

The objective is not to make the business look perfect. It is to make the financial information complete, traceable and properly supported.

1. Confirm Why the Audit Is Required

Before collecting documents, establish exactly why the audit is taking place.

This sounds obvious, but audit requirements can differ significantly depending on the entity and purpose.

For example, an audit may relate to:

• Annual financial statements

• A statutory reporting requirement

• A trust-account or compliance requirement

• Grant or funding conditions

• Internal controls

• A lender or investor requirement

• A contractual obligation

• A specific assurance engagement

• Preparation for a transaction, restructure or sale

Certain entities must have financial reports audited by a registered company auditor, while other businesses may qualify for exemptions or may have different reporting requirements.

Ask these questions at the beginning:

What exactly is being audited?

What reporting framework or criteria apply?

What period is covered?

Who will receive the final report?

What evidence will the auditor require?

When does the final report need to be completed?

Getting these answers early prevents you from preparing documents that are irrelevant while overlooking information the auditor actually needs.

2. Confirm the Audit Scope and Evidence Requirements

Once the purpose of the audit is clear, obtain the auditor’s initial request list.

A professional audit should have a defined scope and evidence process. Your request list may include financial records, reconciliations, contracts, supporting schedules, policies and other documentation.

Do not wait until the first audit meeting to start collecting everything.

Create a checklist based on the auditor’s request and assign responsibility for each item.

3. Make Sure Your Bookkeeping Is Complete

One of the biggest causes of audit delays is incomplete bookkeeping.

Before the audit starts, your accounting system should be brought up to date.

This generally means checking:

• All bank accounts have been reconciled

• Credit card accounts have been reconciled

• Sales and purchases have been recorded correctly

• Accounts receivable balances are up to date

• Accounts payable balances are up to date

• Payroll transactions have been recorded

• Superannuation transactions have been reconciled

• GST and BAS accounts have been reviewed

• Loan balances agree with lender statements

• Fixed asset records are complete

• Unusual or significant transactions have supporting documentation

A clean set of books gives the auditor a reliable starting point and reduces unnecessary questions, follow-ups and delays.g presented.

4. Reconcile Everything Before the Auditor Does

Reconciliations are one of the simplest ways to identify problems before they become audit questions.

At minimum, review your:

• Bank reconciliations

• Credit card reconciliations

• Loan balances

• Payroll liabilities

• GST accounts

• PAYG withholding

• Superannuation payable

• Accounts receivable

• Accounts payable

• Fixed asset register

• Intercompany balances

A reconciliation should not simply show that two numbers are different.

You should understand why they are different and have supporting documentation for outstanding items.

For example, if a bank reconciliation contains old unreconciled transactions, investigate them before the audit.

A clean reconciliation gives the auditor confidence that your underlying records have been reviewed.

5. Prepare Your Financial Statements

Depending on the engagement, the auditor may need to examine financial statements and supporting working papers.

These can include:

• Statement of financial position

• Profit and loss statement

• Cash-flow statement

• Statement of changes in equity

• Notes to the financial statements

• Supporting schedules

• General ledger

• Trial balance

ASIC notes that financial reports can include financial statements, notes, directors' declarations, directors' reports and the auditor's report, depending on the entity and reporting requirements.

Before providing the statements to the auditor, review them for obvious inconsistencies.

For example:

• Does revenue agree with your underlying records?

• Do bank balances agree with reconciliations?

• Do loan balances agree with lender statements?

• Are major expenses supported?

• Are unusual movements understood?

• Are comparative figures reasonable?

• Are balance-sheet accounts supported by schedules?

The more questions you answer internally, the fewer surprises you are likely to face during the audit.

6. Gather Supporting Documents for Major Transactions

Auditors may pay particular attention to transactions that are unusual, material or involve significant judgement.

Create a separate folder for major transactions such as:

• Property purchases

• Business acquisitions

• Asset sales

• Large loans

• Related-party transactions

• New financing arrangements

• Significant contracts

• Restructures

• Capital raising

• Major asset write-offs

• Unusual revenue arrangements

For each significant transaction, keep the relevant contract, invoice, approval, payment record and accounting treatment together where practical.

This makes it easier to explain not just what happened, but why it was recorded the way it was.

7. Review Accounting Estimates and Judgements

Some of the most important audit questions relate to areas where management has had to make a judgement.

Examples may include:

• Asset impairment

• Bad debts

• Inventory valuation

• Depreciation

• Provisions

• Revenue recognition

• Financial instruments

• Going-concern considerations

• Other significant estimates

ASIC's current 2026–27 financial reporting focus areas include revenue recognition, asset impairment and recognition and measurement of financial instruments, among other areas requiring significant judgement.

If your business has made a significant accounting judgement, prepare documentation explaining:

What decision was made?

Why was it made?

What information supports it?

What assumptions were used?

Who reviewed or approved it?

Do not wait for the auditor to ask these questions.

8. Review Your Internal Controls

An audit is not simply about checking whether the numbers add up.

Depending on the engagement, auditors may consider processes and controls relevant to the financial information being examined.

Review basic controls such as:

• Who can approve payments?

• Who can create suppliers?

• Who can access the accounting system?

• Who reviews bank reconciliations?

• Who approves payroll?

• Who approves large purchases?

• Who reviews financial reports?

• How are changes to accounting records controlled?

• How are sensitive documents stored?

• How are errors identified and corrected?

ASIC states that companies should have appropriate governance arrangements, processes and controls supporting high-quality financial reporting.

You do not necessarily need a complicated control framework.

The important thing is that key financial processes are clear, consistent and appropriately controlled.

9. Create a Central Audit Folder

One of the easiest ways to make an audit more efficient is to create a structured digital evidence folder.

For example:

01 – Financial Statements

02 – Bank & Cash

03 – Revenue

04 – Accounts Receivable

05 – Expenses

06 – Accounts Payable

07 – Payroll & Super

08 – Tax & BAS

09 – Fixed Assets

10 – Loans & Finance

11 – Contracts

12 – Related Parties

13 – Internal Controls

14 – Board & Management Documentation

15 – Audit Responses

The exact structure can be changed according to your business.

The objective is simple: when the auditor asks for something, you should know where it is.

ASIC confirms that financial records may be electronic, provided the required records can be produced appropriately, and companies generally need to retain financial records for at least seven years.

10. Assign One Person to Coordinate the Audit

Audits become unnecessarily inefficient when five different people respond to the auditor independently.

Nominate one person as the audit coordinator.

That person can:

• Receive requests

• Assign tasks

• Track outstanding items

• Review responses

• Upload evidence

• Communicate with management

• Escalate difficult questions

For larger organisations, the coordinator can maintain an audit request tracker.

A simple tracker might include:

RequestOwnerStatusDue DateBank confirmationsFinanceComplete10 AugRevenue testingFinanceIn progress12 AugFixed asset registerOperationsComplete12 AugLoan documentationCFOPending14 Aug

This prevents requests from disappearing into email threads.

11. Do Not Hide Known Problems

If you already know about an accounting error, missing document or unusual transaction, raise it early.

Trying to hide a problem rarely makes an audit easier.

Instead, prepare an explanation and supporting documentation.

For example:

"We identified this reconciliation difference during our internal review. It relates to a transaction incorrectly coded in June. We have corrected the accounting entry and attached the supporting documentation."

That is far more useful than allowing the auditor to discover the issue independently.

Management and company officers are expected to provide auditors with the explanations and information required for the audit.

12. Understand the Difference Between Audit Preparation and Audit Remediation

There is an important distinction between preparing records for an audit and fixing weaknesses discovered during an audit.

Audit preparation means getting your existing information organised and ready.

Remediation means correcting identified issues.

Examples of remediation could include:

• Correcting accounting errors

• Updating policies

• Improving approval processes

• Reconciling old balances

• Fixing documentation gaps

• Strengthening segregation of duties

In some engagements, remediation support may be available, but professional independence requirements need to be considered. ASIC emphasises that auditors must remain independent from the entities they audit.

For that reason, clarify roles before asking an audit provider or related adviser to fix an issue that could affect the audit.

Common Audit Preparation Mistakes

Businesses often make the same mistakes before an audit.

Leaving everything until the last minute

A large document request is difficult to manage when nobody has prepared in advance.

Assuming the accounting software is enough

Having everything in Xero, MYOB or another platform does not automatically mean every balance is properly supported.

Ignoring old reconciliation items

Old unreconciled transactions can become a source of unnecessary questions.

Failing to document significant decisions

If a major accounting treatment depends on management judgement, document the reasoning.

Giving incomplete answers

If an auditor asks a specific question, provide a clear response and supporting evidence rather than sending unrelated documents.

Treating the auditor as the person responsible for your financial records

Management remains responsible for the financial report and underlying information. The auditor provides an independent opinion or assurance within the agreed engagement.

Frequently Asked Questions

How long does it take to prepare for an audit?

It depends on the size and complexity of the organisation, the quality of the accounting records and the type of audit. Businesses with organised monthly bookkeeping and reconciliations generally have a much easier preparation process than businesses that need to reconstruct records at year-end.

What documents do I need for an audit?

Common documents include financial statements, trial balances, general ledgers, bank statements, reconciliations, invoices, contracts, payroll records, tax records, loan documents, asset registers and supporting schedules. The exact evidence depends on the audit scope.

What happens if I cannot provide a document requested by the auditor?

Tell the auditor or audit coordinator promptly. Explain what is missing and whether alternative evidence is available. Do not simply ignore the request.

Can an accountant prepare my business for an audit?

Yes, depending on the accountant's role, expertise and the nature of the engagement. Audit preparation can involve bookkeeping cleanup, reconciliations, financial reporting and evidence organisation. Independence requirements must be considered where the same professional or firm is involved in the audit itself.

Do all Australian businesses need an audit?

No. Audit requirements depend on the entity, its circumstances and the applicable legislation or other requirements. Certain companies must have their financial reports audited, while some proprietary companies may qualify for exemptions or audit relief.

How far in advance should I prepare for an audit?

Ideally, audit preparation should be part of your normal financial management rather than a once-a-year exercise. At minimum, start several weeks before the expected audit so you have time to identify missing documents, investigate discrepancies and resolve straightforward issues.

Can Daintree Consulting help prepare my business for an audit?
