Australia has states, not provinces. There are six of them: New South Wales, Victoria, Queensland, Western Australia, South Australia, and Tasmania. Alongside the states sit two self-governing mainland territories, the Australian Capital Territory and the Northern Territory, plus several smaller and external territories. The choice of “state” over “province” is not just vocabulary. It reflects how the country was put together, and it carries real consequences for how much power each part of Australia holds.1Parliament of Australia. Origins of the First Australian Parliament
Why Australia Uses “States”
Before 1901, Australia was six separate British colonies, each with its own parliament, laws, and governor. When delegates drafted the Australian Constitution in the 1890s, they borrowed heavily from the United States model, where formerly independent entities joined a union while keeping significant sovereignty for themselves. The word “states” reflected that idea: each colony was agreeing to share power with a new central government, not being subdivided by one.
Countries that use “provinces” tend to work the other way around, with a central government carving out administrative regions and delegating authority downward. Canada is the usual comparison. Australia built upward from self-governing colonies, and the terminology followed. The colonies federated into the Commonwealth of Australia on January 1, 1901, and the label has stayed put ever since.2Parliamentary Education Office. The Federation of Australia
The Six States
Each state has its own constitution, parliament, government, and court system.3Parliament of Australia. The Australian System of Government
- New South Wales is the oldest, originally established as a penal colony in 1788 and now home to Sydney, the country’s largest city and financial center.
- Victoria separated from New South Wales in 1851 and grew rapidly during the gold rush. Melbourne, its capital, is the second-largest city.
- Queensland occupies the northeastern portion of the continent, known for its extensive coastline and agricultural production.
- Western Australia covers roughly a third of the continent’s landmass and is a major hub for mining and resource extraction.
- South Australia is distinct among mainland states as a free-settler colony that was never used for convict transportation.
- Tasmania is the only island state, separated from the mainland by Bass Strait, with a cooler climate and rugged terrain.
Why Territories Aren’t States
The Australian Capital Territory and the Northern Territory function day-to-day much like states. Each has an elected legislature, a head of government, and responsibility for local services. But they are not states, and the difference is written into the Constitution.4Parliamentary Education Office. Why Does Australia Have 6 Separate States
Section 106 preserves each state’s own constitution, and Section 107 keeps every power a colonial parliament held before federation, unless the Constitution specifically hands it to the Commonwealth. Lawyers call this “residual power,” and it’s the reason states control areas like education, health care, and policing without needing federal permission.5Parliamentary Education Office. Chapter V – The States – Section: 107. Saving of Power of State Parliaments
Territories have no equivalent protection. Section 122 gives the federal parliament broad authority to “make laws for the government of any territory,” which means the Commonwealth can override or repeal any law passed by a territory legislature.6Parliamentary Education Office. The Responsibilities of the Three Levels of Government The Northern Territory got self-governance through the Northern Territory (Self-Government) Act 1978,7Federal Register of Legislation. Northern Territory (Self-Government) Act 1978 and the ACT followed with the Australian Capital Territory (Self-Government) Act 1988.8Documenting Democracy. Australian Capital Territory In both cases, self-government was granted by federal legislation and could, in principle, be withdrawn the same way. That is not a theoretical concern: in 2015, the federal parliament abolished Norfolk Island’s Legislative Assembly and replaced it with a regional council that began operating on July 1, 2016.9Parliament of Australia.

Australia also administers external territories, including Christmas Island and the Cocos (Keeling) Islands in the Indian Ocean. A small mainland territory, Jervis Bay, was separated from New South Wales to give the landlocked ACT access to the sea.
Why the Distinction Matters
The gap between states and territories shows up in federal representation. Each of the six states elects 12 senators, for 72 in total. The ACT and Northern Territory each elect only two, bringing the Senate to 76.10Parliament of Australia. Senate That six-to-one ratio gives territory residents far less influence in the upper house than state residents of comparable population.
The imbalance extends to constitutional change. Amending the Australian Constitution requires a national referendum that passes a “double majority”: a majority of all voters nationwide, and a majority of voters in at least four of the six states. Votes cast by ACT and Northern Territory residents count only toward the national total. They do not count toward the state-by-state threshold.11Parliamentary Education Office. Referendums and Plebiscites
So when Australians talk about states, they are pointing to something more specific than a regional label. A state has constitutional sovereignty that predates the federal government. A territory has whatever powers the federal parliament chooses to grant it. Provinces, in the sense used in Canada or elsewhere, don’t fit either description, which is why Australia doesn’t use the word.
