The Australian Government's Consolidated fund is known as the Consolidated Revenue Fund (CRF). The CRF is established through sections 81 to 83 of the Constitution of Australia. The constitution gives no guidance as to how the revenues or monies that form the CRF are to be kept or accounted for as the CRF is said to be "self‑executing" – that is, all money paid to the Commonwealth automatically forms part of the CRF, whether or not it has been credited to a fund or a bank account. Instead, accounting and banking practices pertaining to government funds are established in the Public Governance, Performance and Accountability Act 2013. The Act requires that the Commonwealth maintains a central bank account with the Reserve Bank of Australia known as the Official Public Account (OPA). The act also allows for non-corporate Commonwealth entities (NCEs) to account for and retain their receipts provided they have legislative and policy authority from the Prime Minister or Cabinet. However, most money collected by NCEs is treated as general government revenue that is not retainable and must be remitted to the OPA.
