Competition law in Australia, also known as antitrust law, is a set of regulations aimed at promoting fair competition in the marketplace by preventing anti-competitive conduct, including monopolies, price-fixing, and other practices that hinder free trade. The Competition and Consumer Act of 2010 is the primary legislation governing competition law in Australia. The Act is enforced by the Australian Competition and Consumer Commission (ACCC), which is responsible for monitoring and regulating competition in the marketplace.
