The Auditor-General Act 1997 establishes the mandate for the Auditor General to undertake financial statement audits of all Commonwealth entities including those of government agencies, statutory authorities and government business enterprises.

Financial statement audits are an independent examination of the financial accounting and reporting of public sector entities. The results of the examination are presented in an audit report, which expresses the auditor's opinion on whether the financial statements as a whole and the information contained therein fairly present each entity's financial position and the results of its operations and cash flows. The accounting treatments and disclosures reflected in the financial statements by the entity are assessed against relevant accounting standards and legislative reporting requirements.
