Parliament of Australia: structure, history and principal functions
The federal Parliament of Australia is the national legislature established in 1901. This article outlines its composition, constitutional basis, major roles, historical development and how it operates today.
The Parliament of Australia is the federal legislature created by the Australian Constitution at the time of federation in 1901. It sits at Parliament House in Canberra and exercises the principal law‑making powers of the Commonwealth. The institution combines elements of the British Westminster model and features drawn from other systems, forming a distinct Australian practice of representative and responsible government. The constitutional text and subsequent legislation set out the parliament's composition, powers and procedures; interpretation of those provisions has evolved through political practice and court rulings. Federal arrangements and national institutions are central to how the parliament functions within Australia, while the chosen parliamentary system shapes everyday operations.

Composition and principal features
Australia has a bicameral parliament composed of two separate chambers. The lower chamber, the House of Representatives, is the primary forum for forming government and representing the population by electorate. The upper chamber, the Senate, is designed as a house of review and represents the states and territories; it provides a balance to the lower house by scrutinising and amending proposed laws. Members of both chambers participate in debates, vote on legislation and serve on parliamentary committees that examine policy, administration and public spending.
Main functions
- Legislation: The parliament debates, amends and passes laws that apply across the nation.
- Representation: Elected members represent citizens and regional interests in parliamentary proceedings.
- Scrutiny and accountability: Parliament monitors executive government through question time, committee inquiries and parliamentary processes.
- Government formation: The government is formed from the party or coalition that commands support in the lower house and is held accountable by parliament.
Origins and historical development
When the six British colonies federated on 1 January 1901, the Commonwealth of Australia was created and a new national parliament established. The first sitting of the federal parliament occurred in Melbourne at the Royal Exhibition Building, after which sessions continued in Melbourne until the national capital was ready. The decision to locate the seat of government in Canberra reflected a compromise between major cities and the new parliament moved there in 1927. A purpose-built Parliament House was later completed and opened in 1988 to replace the provisional facilities used earlier.
Procedures, committees and legal framework
The Australian Constitution defines the broad legislative powers of parliament and establishes procedures for passing laws, including how the two chambers interact when a bill is proposed. Parliamentary committees play a prominent role in detailed scrutiny, gathering evidence from experts, public bodies and citizens. Regular practices such as question time, debates and supply measures provide mechanisms for ministers to answer parliament and for representatives to raise matters of public concern. The institutional rules and standing orders of each chamber further guide daily business.
Distinctive aspects and public importance
Several features distinguish the Parliament of Australia: its blend of Westminster conventions with federal checks and balances; a powerful senate that can act independently of the government; and a highly developed committee system. These traits shape national policymaking and public accountability. For further context on comparative influences and political traditions, see materials about the United Kingdom model and the Westminster system, as well as references to adaptations from the United States Congress. Historical sittings and locations are documented in accounts of early meetings in Melbourne and the later relocation to the national capital.
History
The Commonwealth Parliament opened in Melbourne on 9 May 1901. The only building in the whole of Melbourne large enough to accommodate the 14,000 guests was the Royal Exhibition Building. From 1901 to 1927, they met in Old Parliament House, borrowed from the Parliament of Victoria (which moved to the Royal Exhibition Building instead). On 9 May 1927, Parliament moved to the new capital, Canberra. In what was intended only as a transitional building, the Australian Parliament eventually met for over 60 years. The current Parliament House was opened on 9 May 1988. Australia has the fourth longest continuously functioning democracy in the world.
Composition
Under Section 1 of the Australian Constitution, it is stated that the British Queen is a constituent of Parliament. However, the Governor-General of Australia actively conducts day-to-day political business as a representative of the British Crown. He is appointed on the advice of the Prime Minister.
The upper house in the Australian Parliament is the Senate, which has 76 members. Like the United States Senate, which it was modeled after, the Senate has an equal number of members from each state regardless of its population. The Constitution allows Parliament to change the number of Senators, but all six Australianstates must be equally represented. Furthermore, each founding state must be represented by at least six senators.
Until 1949, each state could elect the constitutional minimum number of six senators. From 1949 onwards, ten and, since 1984, twelve representatives of each state were allowed to be elected.
Parliament can determine the number of deputies in the House of Representatives. However, according to the Constitution, the number should be at least twice the number of senators. According to the Constitution, the lower house has 151 deputies. Each state gets seats according to its population, with each founding state having at least five seats secured. According to the Constitution, no representation of the territories is secured. In 1922, the Northern Territory was given a seat and so was the Capital Territory in 1948. However, this limited representation only lasted until 1968.
From 1901 to 1949 there were always 74 or 75 members in the house. Between 1949 and 1984, it had between 121 and 127 members. Since 1984, the House of Commons has always had between 148 and 151 Members.
