Audit Engagement Letter Template for Australia

An Audit Engagement Letter is a mandatory legal document that formalises the contractual relationship between your audit firm and client company in Australia. You must issue this letter before commencing any audit work to comply with Australian Auditing Standards and establish clear expectations for both parties throughout the engagement process.

When do you need this document?

You need an Audit Engagement Letter for every new audit client relationship and must renew it annually for ongoing engagements. This requirement applies whether you're conducting statutory audits mandated by the Corporations Act 2001 for public companies, large proprietary companies, or registered schemes, or voluntary audits requested by private companies, not-for-profits, or government entities. You also need a new letter when there are significant changes to engagement terms, such as modifications to audit scope, fee arrangements, or key personnel assignments. The letter is essential for compliance audits, group audits involving multiple entities, and specialised audits of financial services organisations.

Key legal considerations

Your Audit Engagement Letter must address several critical legal elements to protect both parties and ensure regulatory compliance. The scope clause must clearly define which financial statements will be audited and specify the applicable financial reporting framework, whether Australian Accounting Standards, International Financial Reporting Standards, or special purpose frameworks. You need detailed responsibility allocations covering management's obligations for preparing financial statements, maintaining internal controls, and providing access to records, while outlining your duties regarding audit planning, evidence gathering, and reporting. Independence clauses are crucial under APES 110, requiring disclosure of any relationships or services that might compromise objectivity. Limitation of liability provisions help manage professional risks, while confidentiality clauses protect sensitive client information under the Privacy Act 1988.

Legal requirements in Australia

Australian law mandates specific requirements for audit engagement documentation under ASA 210, which requires written confirmation of audit terms before work commences. The Corporations Act 2001 establishes statutory audit obligations for certain companies and specifies auditor appointment procedures through shareholder resolutions or ASIC intervention. Your letter must acknowledge compliance with Australian Auditing Standards issued by the AUASB, including risk assessment procedures, materiality considerations, and reporting timelines. APES 110 ethical requirements demand clear statements about independence, objectivity, and professional competence. For listed companies, additional Corporations Regulations and ASX Listing Rules may apply, requiring specific audit committee communications and continuous disclosure obligations. ASIC oversight means your engagement letters may be subject to regulatory review, particularly for public interest entities.
