What it does
The Auditor-General Act 1997 (Cth) is the primary Commonwealth statute governing the independent audit of Commonwealth public finances and performance. It establishes the Auditor-General for the Commonwealth as an independent officer of the Parliament (s 8), creates the Australian National Audit Office (ANAO) as a listed Commonwealth entity (s 38), and prescribes the Auditor-General's functions, powers, information-gathering rights, secrecy obligations, and appointment conditions.
The Act commenced on the same day as the Financial Management and Accountability Act 1997 (s 2) and operates in close conjunction with the Public Governance, Performance and Accountability Act 2013 (PGPA Act), which defines the entities, companies and associated entities to which the audit regime applies.
The centrepiece of the Act is the independence guarantee in s 8(4): the Auditor-General has complete discretion in the performance or exercise of functions and powers and is not subject to direction from anyone in relation to whether or not a particular audit is to be conducted, the way it is conducted, or the priority to be given to any matter. This independence is structural: it ensures that audit outcomes are not coloured by political or executive preferences.
