The South Australia Act 1834 (4 & 5 Will. 4. c. 95), or Foundation Act 1834 and also known as the South Australian Colonization Act, was an Act of the Parliament of the United Kingdom which provided for the settlement of a province or multiple provinces on the lands between 132 degrees east and 141 degrees of east longitude, and between the Southern Ocean, and 26 degrees south latitude, including the islands adjacent to the coastline.
It also set up a London-based Board of the South Australian Colonization Commission allowing for three or more appointed commissioners (board members), known as the Colonization Commissioners for South Australia or, later, Colonisation Commissioners, to oversee the sale and leasing of land in South Australia to British subjects. This Board was to be represented in the new colony by a Resident Commissioner, Surveyor-General, an Emigration Agent and various other colonial officers.
