South Australia Act 1842 in the context of "South Australian Colonization Commission"

British colonisation of South Australia describes the planning and establishment of the colony of South Australia by the British government, covering the period from 1829, when the idea was raised by the then-imprisoned Edward Gibbon Wakefield, to 1842, when the South Australia Act 1842 changed the form of government to a Crown colony.

Ideas espoused and promulgated by Wakefield since 1829 led to the formation of the South Australian Land Company in 1831, but this first attempt failed to achieve its goals, and the company folded.

The history of South Australia includes the history of the Australian state of South Australia since Federation in 1901, and the area's preceding Indigenous and British colonial societies. Aboriginal Australians of various nations or tribes have lived in South Australia for at least thirty thousand years, while British colonists arrived in the 19th century to establish a free colony. The South Australia Act, 1834 created the Province of South Australia, built according to the principles of systematic colonisation, with no convict settlers.

After the colony nearly went bankrupt, the South Australia Act 1842 gave the British Government full control of South Australia as a Crown Colony. After some amendments to the form of government in the intervening years, South Australia became a self-governing colony in 1857 with the ratification of the Constitution Act 1856, and the Parliament of South Australia was formed.
