The audit reviewed six budget-funded agencies (Australian Customs Service, Australian Taxation Office, Centrelink, Department of Defence, Department of Education, Training and Youth Affairs, and Department of Immigration and Multicultural Affairs) and two off-budget entities (Airservices Australia and Reserve Bank of Australia). The ANAO also examined the Office for Government Online's (OGO, formerly the Office of Government Information Technology, or OGIT) whole-of-government coordination of the Commonwealth's Year 2000 efforts.
