Colonial expansion
The British continued to push into other areas of the continent in the early 19th century, initially along the coast. In 1803, a settlement was established in Van Diemen's Land (present-day Tasmania), and in 1813, Gregory Blaxland, William Lawson and William Wentworth crossed the Blue Mountains west of Sydney, opening the interior to European settlement. The British claim extended to the whole Australian continent in 1827 when Major Edmund Lockyer established a settlement on King George Sound (modern-day Albany). The Swan River Colony (present-day Perth) was established in 1829, evolving into the largest Australian colony by area, Western Australia. In accordance with population growth, separate colonies were carved from New South Wales: Tasmania in 1825, South Australia in 1836, New Zealand in 1841, Victoria in 1851, and Queensland in 1859. South Australia was founded as a "free province" — it was never a penal colony. Western Australia was also founded "free" but later accepted transported convicts, the last of which arrived in 1868, decades after transportation had ceased to the other colonies.In 1823, a Legislative Council nominated by the governor of New South Wales was established, together with a new Supreme Court, thus limiting the powers of colonial governors. Between 1855 and 1890, the six colonies individually gained responsible government, thus becoming elective democracies managing most of their own affairs while remaining part of the British Empire. The Colonial Office in London retained control of some matters, notably foreign affairs and defence.In the mid-19th century, explorers such as Burke and Wills went further inland to determine its agricultural potential and answer scientific questions. A series of gold rushes beginning in the early 1850s led to an influx of new migrants from China, North America and continental Europe, as well as outbreaks of bushranging and civil unrest; the latter peaked in 1854 when Ballarat miners launched the Eureka Rebellion against gold license fees.From 1886, Australian colonial governments began introducing policies resulting in the removal of many Aboriginal children from their families and communities (referred to as the Stolen Generations).States and territories
Australia has six states — New South Wales (NSW), Queensland (QLD), South Australia (SA), Tasmania (TAS), Victoria (VIC) and Western Australia (WA) — and three mainland territories—the Australian Capital Territory (ACT), the Northern Territory (NT), and the Jervis Bay Territory (JBT). In most respects, the ACT and NT function as states, except that the Commonwealth Parliament has the power to modify or repeal any legislation passed by the territory parliaments.Under the constitution, the states essentially have plenary legislative power to legislate on any subject, whereas the Commonwealth (federal) Parliament may legislate only within the subject areas enumerated under section 51. For example, state parliaments have the power to legislate with respect to education, criminal law and state police, health, transport, and local government, but the Commonwealth Parliament does not have any specific power to legislate in these areas. However, Commonwealth laws prevail over state laws to the extent of the inconsistency.Each state and major mainland territory has its own parliament — unicameral in the Northern Territory, the ACT and Queensland, and bicameral in the other states. The states are sovereign entities, although subject to certain powers of the Commonwealth as defined by the Constitution. The lower houses are known as the Legislative Assembly (the House of Assembly in South Australia and Tasmania); the upper houses are known as the Legislative Council. The head of the government in each state is the Premier and in each territory the Chief Minister. The King is represented in each state by a governor; and in the Northern Territory, the administrator. In the Commonwealth, the King's representative is the governor-general.The Commonwealth Parliament also directly administers the external territories of Ashmore and Cartier Islands, Christmas Island, the Cocos (Keeling) Islands, the Coral Sea Islands, Heard Island and McDonald Islands, and the claimed region of Australian Antarctic Territory, as well as the internal Jervis Bay Territory, a naval base and sea port for the national capital in land that was formerly part of New South Wales. The external territory of Norfolk Island previously exercised considerable autonomy under the Norfolk Island Act 1979 through its own legislative assembly and an Administrator to represent the monarch. In 2015, the Commonwealth Parliament abolished self-government, integrating Norfolk Island into the Australian tax and welfare systems and replacing its legislative assembly with a council. Macquarie Island is part of Tasmania, and Lord Howe Island of New South Wales.
