The prime minister of Australia is the leader of the Australian Government and the Cabinet of Australia, with the support of the majority of the House of Representatives. Thirty-one people have served in the position since the office was created in 1901. The role of prime minister is not mentioned in the Constitution of Australia, but the prime minister is still appointed by the governor-general who under Section 64 of the constitution has the executive power to appoint ministers of state. The governor-general is appointed by the monarch of Australia based on the advice of the incumbent prime minister. Governors-general do not have fixed terms, but usually serve for five years.
