The Parliament consists of two Houses (the Senate and the House of Representatives), and the King, represented in Australia by the Governor General.

In 1901 the Australian Constitution established the Australian Parliament, also known as the federal Parliament or the Commonwealth Parliament.

The Australian Parliament has four main roles:

  • Making and changing federal laws.
  • Representing the people of Australia.
  • Providing a place where government is formed.
  • Keeping a check on the work of the government



The Senate is one of the two houses of the Australian Federal Parliament. It consists of 76 senators, twelve from each of the six states and two from each of the mainland territories. It shares the power to make laws with the other House of the Parliament, the House of Representatives.

House of Representatives

The House of Representatives is one of the two Houses of Parliament and is sometimes called ‘the People’s House’ or the ‘house of government’. The party, or parties, that hold a majority of seats in the House form government. There are currently 151 Members of the House of Representatives who each represent an electorate.

Parliamentary Departments

The work of the Australian Parliament – its Members, Senators and parliamentary committees – is supported by four separate departments:

Note: Information about the legal framework for these four departments is contained in the Parliamentary Service Act 1999

Publications and policies
