The South Australian Company, also referred to as the South Australia Company, was formed in London on 9 October 1835, after the South Australia (Foundation) Act 1834 had established the new British Province of South Australia, with the South Australian Colonization Commission set up to oversee implementation of the Act.
The South Australian Company was a commercial enterprise, and not officially connected to the British Government or the Colonization Commission, but turned out to be indispensable in allowing emigration to the new colony to begin. The founding board of the company, headed by George Fife Angas, consisted of wealthy British merchants, with the purpose of developing a new settlement in South Australia, building a new colony by meeting an essential financial obligations of the South Australia Act 1834. It bought up unsold land to the level required by the Act for emigration to be allowed to begin.
During the first years of settlement, the company built a great deal of infrastructure and contributed to the creation of industries such as fishing and mining, and it continued to play an important part in the business affairs of the colony (and later state) of South Australia for over a hundred years. It ended business in its own right on 17 March 1949, when it was liquidated by Elders Trustee & Executor Company Ltd. Many streets in Adelaide were named after men associated with the company.
