The states and territories are federated administrative divisions in Australia, ruled by regional governments that constitute the second level of governance between the federal government and local governments. States are self-governing regions with their own constitutions, legislatures, departments, and certain civil authorities (e.g. judiciary and law enforcement) that administer and deliver most public policies and programmes. Territories administer local policies and programmes much like the states, but are constitutionally and financially subordinate to the federal government.

The Federation of Australia constitutionally consists of six federated states (New South Wales, Queensland, South Australia, Tasmania, Victoria, and Western Australia) and ten federal territories, out of which three are internal territories (the Australian Capital Territory, Jervis Bay Territory, and Northern Territory) contiguous to the Australian mainland; and the other seven are external territories (Ashmore and Cartier Islands, Christmas Island, the Cocos (Keeling) Islands, Coral Sea Islands, Heard Island and McDonald Islands, Norfolk Island, and the Australian Antarctic Territory), which are offshore dependent territories. Every state and internal territory (excluding the Jervis Bay Territory, which is a federal district with no autonomy, bundled under the ACT in elections and censuses) is self-governing with its own independent executive government, legislative branch, and judicial system, while the rest only have local government status overseen by federal departments.

State and territory governments have executive authority to legislate on matters concerning their citizens, with the only limitations being on sovereign subjects of national importance such as defence, foreign policy, and border control. Each state and internal territory, excluding the Jervis Bay Territory, also has its own legislature, although the federal government can overwrite any state/territorial legislation. The federal High Court of Australia acts as a final court of appeal for all matters and has the authority to override any state judiciary. While all states and internal territories have their own judicial system, which is subject to appeal from the High Court, most external territories are subject to the judiciary and legislature of either a state or internal territory. Excluding the Heard Island and McDonald Islands and the Australian Antarctic Territory (which are governed by the Department of Agriculture, Water and the Environment), the external territories are governed by the federal Department of Infrastructure, Transport, Regional Development and Communications.^[1]

Each state of Australia is a successor to historical British colonies and each has its own state/territorial constitution. The Australian Capital Territory (ACT) and Northern Territory for the most part operate indistinguishably from the states, even though they do not have constitutional status as states. The Jervis Bay Territory is considered an exclave of the ACT for almost all purposes. Until 2015, Norfolk Island was also a self-governing territory like the ACT.

Geography[]

Surrounded by the Indian, Pacific, and (disputedly) Southern oceans, Australia is separated from Maritime Southeast Asia and New Guinea by the Arafura Sea, Timor Sea, and Torres Strait, from the Melanesian islands by the Coral Sea, and from New Zealand by the Tasman Sea. The world's smallest continent, Australia is also the sixth largest country by land area and sometimes considered the world's largest island. Australia has a mainland coastline of 34,218 kilometres (21,262 mi) and claims an Exclusive Economic Zone of 8,148,250 square kilometres (3,146,060 sq mi).^{[citation needed]}

States and territories[]

At Federation in 1901, what is now the Northern Territory was within South Australia, what are now the Australian Capital Territory and the Jervis Bay Territory were within New South Wales, and Coral Sea Islands was part of Queensland. Ashmore and Cartier Islands was accepted by Australia in 1934^[2] and was annexed to the Northern Territory prior to adoption of the Statute of Westminster in 1942, deemed effective from 1939; it has thus become part of Australia.

Each external territory is regulated by an Act of the federal Parliament. These Acts contain the majority of provisions determining the legal and political structure applying in that external territory. Under s 122 of the Australian Constitution the federal Parliament plenary power to make laws for all territories including all external territories.^[9]

The Cocos (Keeling) Islands voted for integration in 1984. Together with Christmas Island, Commonwealth laws apply automatically to the territory unless expressly stated otherwise^[10] and residents of both external territories are associated with Northern Territory for federal elections. They are, thus, constitutionally part of Australia.

The Heard Island and McDonald Islands, although uninhabited, are treated as constitutionally part of Australia by the central government.^[11]

The constitutional status of the Australian Antarctic Territory is unclear, with successive governments treating it either as a separate territory (as in Norway and the United Kingdom) or an integral part of the country (as in France and New Zealand). As of 2018, the present government appears to take the view that it is not constitutionally a part of Australia.^[12]

Norfolk Island's status is controversial, with the present (as of 2018) government taking measures to integrate the territory into Australia proper (including representation in parliament and compulsory voting). The Norfolk Islanders have not formally consented to this change in constitutional status and assert that they are not Australian.^[13]

Former territories[]

Internal[]

Two internal territories established by the Australian federal government under Section 122 of the Constitution of Australia no longer exist:

• Central Australia (1926–1931), consisting of the area of the current Northern Territory south of the 20th parallel south^[23]
• North Australia (1926–1931), consisting of the area of the current Northern Territory north of the 20th parallel south^[23]

External[]

Two present-day Oceanic countries, Papua New Guinea (PNG) and Nauru, were administered by the federal government of Australia as de facto and/or de jure external territories for differing periods between 1902 and 1975.

Papua and New Guinea (1883–1949)[]

• Territory of Papua:
  • 1883–1902: A de facto part of Queensland (de jure British territory in 1888–1900)
  • 1902–1949: An external territory of Australia
• Territory of New Guinea: 1920–1949, under a League of Nations mandate. The territory was previously known as German New Guinea between 1884 and 1914; it was formally under Australian military occupation in 1914–1920).

Following World War II, the Papua and New Guinea Act 1949 placed the Territory of New Guinea in an "administrative union" with the Territory of Papua, and the combined Territory of Papua and New Guinea was created. However, both territories remained technically distinct for some administrative and legal purposes, until 1975, when the combined entity eventually was given independence as Papua New Guinea.

Nauru (1920–1968)[]

Nauru was previously under the German colonial empire as part of the German New Guinea. Following World War I, the Australian government received a League of Nations mandate for Nauru. After World War II, Territory of Papua, Territory of New Guinea and Nauru were all controlled by the Australian government as United Nations trust territories. Nauru was granted independence in 1968.

Statistics[]

Majority of Australians live in the east coast states of New South Wales, Queensland, Victoria, and the Australian Capital Territory, which have around three-quarters of the Australian population. Most of the major population centres are located east and south of the Great Dividing Range on the coastal plains and their associated hinterland regions.

Statistical divisions[]

The Australian Bureau of Statistics' (ABS) Australian Statistical Geography Standard describes several main statistical divisions of Australia:

• Mesh Block (MB) – the smallest area of division, MBs are rarely used for statistics and represent 30–60 dwellings, though some have no population or development. They are conventionally used as a way to ensure confidentiality of responses.
• Statistical Area Level 1 (SA1) – SA1s are small areas of 200–800 people and are used to balance spatial detail and cross comparison in the Census of Population and Housing.
• Statistical Area Level 2 (SA2) – SA2s are designed to represent financial and social interactions, such as a suburb or neighbourhood of 3,000–25,000 people (averaging at 10,000) and is often the smallest division used in statistical releases.
• Statistical Area Level 3 (SA3) – SA3s are regional representations of local communities, generally containing similar characteristics, administrative boundaries, and labour markets, each having 30,000–130,000 people.
• Statistical Area Level 4 (SA4) – SA4s are broader representations of labour forces in population centres, with 100,000–300,000 people in regional areas and 300,000–500,000 in metropolitan areas.
• States and Territories

The ABS also defines other divisions such as the Greater Capital City Statistical Area Structure, Significant Urban Area Structure, Remoteness Structure, and Indigenous Structure. Other non-ABS divisions include Local Government Areas, Postal Areas, electoral divisions, and tourism regions.^[33]

Background and overview[]

The states originated as separate British colonies prior to Federation in 1901. The Colony of New South Wales was founded in 1788 and originally comprised much of the Australian mainland, as well as Lord Howe Island, New Zealand, Norfolk Island, and Van Diemen's Land, in addition to the area currently referred to as the state of New South Wales. During the 19th century, large areas were successively separated to form the Colony of Tasmania (initially established as a separate colony named Van Diemen's Land in 1825), the Colony of Western Australia (initially established as the smaller Swan River Colony in 1829), the Province of South Australia (1836), the Colony of New Zealand (1840),^[34] the Victoria Colony (1851) and the Colony of Queensland (1859). Upon Federation, the six colonies of New South Wales, Victoria, Queensland, South Australia, Western Australia, and Tasmania became the founding states of the new Commonwealth of Australia.

The legislative powers of the states are protected by the Australian constitution, section 107, and under the principle of federalism, Commonwealth legislation only applies to the states where permitted by the constitution. The territories, by contrast, are from a constitutional perspective directly subject to the Commonwealth Government; laws for territories are determined by the Australian Parliament.^[35]

Most of the territories are directly administered by the Commonwealth Government, while two (the Northern Territory and the Australian Capital Territory) have some degree of self-government although less than that of the states. In the self-governing territories, the Australian Parliament retains the full power to legislate, and can override laws made by the territorial institutions, which it has done on rare occasions. For the purposes of Australian (and joint Australia-New Zealand) intergovernmental bodies, the Northern Territory and the Australian Capital Territory are treated as if they were states.

Each state has a governor, appointed by the monarch (currently Queen Elizabeth II), which by convention she does on the advice of the state premier. The Administrator of the Northern Territory, by contrast, is appointed by the Governor-General. The Australian Capital Territory has neither a Governor nor an Administrator, but the Governor-General exercises some powers that in other jurisdictions are exercised by the Governor of a state or Administrator of a territory, such as the power to dissolve the Legislative Assembly.

Jervis Bay Territory is the only non-self-governing internal territory. Until 1989, it was administered as if it were a part of the ACT, although it has always been a separate territory. Under the terms of the Jervis Bay Territory Acceptance Act 1915,^[36] the laws of the ACT apply to the Jervis Bay Territory insofar as they are applicable and providing they are not inconsistent with an Ordinance.^[37] Although residents of the Jervis Bay Territory are generally subject to laws made by the ACT Legislative Assembly, they are not represented in the Assembly. They are represented in the Parliament of Australia as part of the Electoral Division of Fenner (named the Division of Fraser until 2016) in the ACT and by the ACT's two Senators. In other respects, the territory is administered directly by the Federal Government through the Territories portfolio.^[38]

The external territory of Norfolk Island possessed a degree of self-government from 1979 until 2015.

Each state has a bicameral parliament except Queensland, which abolished its upper house in 1922. The lower house is called the Legislative Assembly, except in South Australia and Tasmania, where it is called the House of Assembly. Tasmania is the only state to use proportional representation for elections to its lower house; all others elect members from single member constituencies, using preferential voting. The upper house is called the Legislative Council and is generally elected from multi-member constituencies using proportional representation. The three self-governing territories, the ACT, the Northern Territory, and Norfolk Island, each have unicameral Legislative Assemblies.

The head of government of each state is called the premier, appointed by the state's Governor. In normal circumstances, the Governor will appoint as premier whoever leads the party or coalition which exercises control of the lower house (in the case of Queensland, the only house) of the state Parliament. However, in times of constitutional crisis, the Governor can appoint someone else as Premier. The head of government of the self-governing internal territories is called the chief minister. The Northern Territory's chief minister, in normal circumstances whoever controls the Legislative Assembly, is appointed by the administrator.

The term "interstate" is used within Australia to refer to a number of events, transactions, registrations, travel, etc. which occurs across borders or outside of the particular state or territory of the user of the term. Examples of use include motor vehicle registration,^[39] travel,^[40] applications to educational institutions out of one's home state.^[41]

There are very few urban areas bifurcated by state/territory borders. The Queensland/New South Wales border runs through Coolangatta (Queensland) and Tweed Heads (New South Wales) and splits Gold Coast Airport. Oaks Estate, a contiguous residential of Queanbeyan, was excised out of New South Wales when the Australian Capital Territory was established in 1909. Some Urban Centres and Localities reported by the Australian Bureau of Statistics include some agglomerations of cities spreading across state borders, including Gold Coast–Tweed Heads, Canberra–Queanbeyan, Albury–Wodonga (New South Wales-Victoria) and Mildura–Wentworth (Victoria-New South Wales)
