Politics of Australia
overview of the political system of Australia
In Australia, politics operates under the written Australian Constitution, which sets out Australia as a constitutional monarchy, governed via a parliamentary democracy in the Westminster tradition. Australia is also a federation, where power is divided between the federal government and the states. The monarch, currently King Charles III, is the head of state and is represented locally by the governor-general, while the head of government is the prime minister, currently Anthony Albanese.
The country has maintained a stable liberal democratic political system under its Constitution, the world's tenth oldest, since Federation in 1901. Australia largely operates as a two-party system in which voting is compulsory. The Economist Intelligence Unit rated Australia a "full democracy" in 2023.
Like other Westminster-style systems of government, Australia's federal system of government consists of three branches: the legislative (Parliament), the executive (the prime minister, the cabinet, other ministers, and government departments), and the judicature (the High Court of Australia and other federal courts). The Australian government consists of the party or coalition that had majority support in the lower house and exercises both executive (as ministers) and legislative (through control of the House) power.
The federal Parliament (as defined in section 1 of the Constitution) comprises the monarch and is bicameral (has two chambers): the House of Representatives (lower house) and Senate (upper house). The House of Representatives has 150 members, each representing an individual electoral district of about 165,000 people.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q1153672. The Library of Congress control number is sh85009597. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1901 and 2023.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
