The Australian Competition and Consumer Commission (ACCC) is the chief competition regulator of the Government of Australia, located within the Department of the Treasury. It was established in 1995 with the amalgamation of the Australian Trade Practices Commission and the Prices Surveillance Authority to administer the Trade Practices Act 1974, which was renamed the Competition and Consumer Act 2010 on 1 January 2011. The ACCC's mandate is to protect consumer rights and business rights and obligations, to perform industry regulation and price monitoring, and to prevent illegal anti-competitive behaviour.

The Department of the Treasury, also known as The Treasury, is the national treasury and financial department of the federal government of the Commonwealth of Australia.
