Government and politics

Australia is a federal parliamentary constitutional monarchy. The country has maintained a stable liberal democratic political system under its constitution, which is one of the world's oldest, since Federation in 1901. It is also one of the world's oldest federations, in which power is divided between the federal and state and territorial governments. The Australian system of government combines elements derived from the political systems of the United Kingdom (a fused executive, constitutional monarchy and strong party discipline) and the United States (federalism, a written constitution and strong bicameralism with an elected upper house), along with distinctive indigenous features.

The federal government is separated into three branches:

Legislature: the bicameral Parliament, comprising the monarch (represented by the governor-general), the Senate, and the House of Representatives;

Executive: the Federal Executive Council, which in practice gives legal effect to the decisions of the cabinet, comprising the prime minister and other ministers of state appointed by the governor-general on the advice of Parliament;

Judiciary: the High Court of Australia and other federal courts, whose judges are appointed by the governor-general on advice of Parliament

Charles III reigns as King of Australia and is represented in Australia by the governor-general at the federal level and by the governors at the state level, who by convention act on the advice of his ministers. Thus, in practice the governor-general acts as a legal figurehead for the actions of the prime minister and the Federal Executive Council. The governor-general, however, does have reserve powers which, in some situations, may be exercised outside the prime minister's request. These powers are held by convention and their scope is unclear. The most notable exercise of these powers was the dismissal of the Whitlam Government in the constitutional crisis of 1975.

In the Senate (the upper house), there are 76 senators: twelve each from the states and two each from the mainland territories (the Australian Capital Territory and the Northern Territory). The House of Representatives (the lower house) has 151 members elected from single-member electoral divisions, commonly known as "electorates" or "seats", allocated to states on the basis of population, with each original state guaranteed a minimum of five seats.Elections for both chambers are normally held every three years simultaneously; senators have overlapping six-year terms except for those from the territories, whose terms are not fixed but are tied to the electoral cycle for the lower house; thus only 40 of the 76 places in the Senate are put to each election unless the cycle is interrupted by a double dissolution.

Australia's electoral system uses preferential voting for all lower house elections with the exception of Tasmania and the ACT which, along with the Senate and most state upper houses, combine it with proportional representation in a system known as the single transferable vote. Voting is compulsory for all enrolled citizens 18 years and over in every jurisdiction, as is enrolment. The party with majority support in the House of Representatives forms the government and its leader becomes Prime Minister. In cases where no party has majority support, the Governor-General has the constitutional power to appoint the Prime Minister and, if necessary, dismiss one that has lost the confidence of Parliament. Due to the relatively unique position of Australia operating as a Westminster parliamentary democracy with an elected upper house, the system has sometimes been referred to as having a "Washminster mutation", or as a semi-parliamentary system.

There are two major political groups that usually form government, federally and in the states: the Australian Labor Party and the Coalition, which is a formal grouping of the Liberal Party and its minor partner, the National Party. The Liberal National Party and the Country Liberal Party are merged state branches in Queensland and the Northern Territory that function as separate parties at a federal level. Within Australian political culture, the Coalition is considered centre-right and the Labor Party is considered centre-left. Independent members and several minor parties have achieved representation in Australian parliaments, mostly in upper houses. The Australian Greens are often considered the "third force" in politics, being the third largest party by both vote and membership.

The most recent federal election was held on 22 May 2022 and resulted in the Australian Labor Party, led by Anthony Albanese, being elected to government.
