Australian Parliament

The Australian Parliament is the federal legislative body of the Commonwealth of Australia, responsible for making laws that govern the nation. Established in 1901 following the federation of six Australian colonies, Parliament operates under a Westminster system of government inherited from the United Kingdom. It consists of two houses: the House of Representatives, commonly called the lower house, and the Senate, known as the upper house. Together with the monarch, represented by the Governor-General, these chambers form the legislative branch of Australia's federal government.

The House of Representatives contains 151 members elected from geographic divisions across Australia, with representation roughly proportional to population. Members serve terms of up to three years, though elections can be called earlier. The political party or coalition that commands a majority in this chamber forms government, with its leader becoming Prime Minister. The House is where most government legislation originates and where the executive government is held accountable through question time and parliamentary debates.

The Senate comprises 76 senators: twelve from each of the six states and two from each of the mainland territories. State senators serve six-year terms, with half facing election every three years, while territory senators face election whenever the House is dissolved. The Senate functions as a house of review, scrutinizing legislation passed by the lower house and conducting detailed committee inquiries into government activities and policy matters. Its composition often differs from the House, giving minor parties and independents greater influence.

Parliament sits in Parliament House, an iconic building in Canberra designed by American architect Romaldo Giurgola and opened in 1988. The building replaced the provisional Old Parliament House, where federal lawmakers met from 1927 until the move. Canberra itself was chosen as the capital through constitutional compromise, located between the rival cities of Sydney and Melbourne.

The legislative process requires bills to pass both houses before receiving royal assent from the Governor-General. Most bills are introduced by government ministers, though private members can also propose legislation. Parliamentary committees play a crucial role in examining proposed laws, investigating issues of public concern, and scrutinizing government expenditure. These committees often hold public hearings and produce reports that influence policy development.

Parliament's functions extend beyond lawmaking. It serves as a forum for national debate, provides oversight of the executive branch, and represents the diverse interests of Australians. Question time allows opposition members to challenge ministers, while parliamentary privilege protects members' freedom of speech during proceedings. The Parliament also controls government finances through its power to approve or reject budget appropriations.

Australian citizens aged eighteen and over are required to vote in federal elections under compulsory voting laws introduced in 1924. This system consistently produces high voter turnout and is considered a distinctive feature of Australian democracy. Voting uses preferential or proportional representation systems depending on the chamber, ensuring that elected representatives reflect a broad spectrum of voter preferences.
