Robert Gouger and Edward Gibbon Wakefield were both looking to start a colony based on free settlement. Gouger met with Wakefield (who was still in prison at the time) in January 1829, and Wakefield suggested that instead of granting free land to settlers as had happened in other colonies, the colony should use the principle of "the universal sale of land instead of land grants, and the exclusive employment of the purchasers' moneys to promote emigration". Gouger established the National Colonisation Society in February 1830, and although initially the proposal didn't attract much attention, after Sturt's discovery of the Murray River became public knowledge, its prospects were revived. By December, the Gulf St Vincent was being pitched as the location of the colony, and the National Colonisation Society put their proposal to the Colonial Office in May 1831. Founding organisations and laws, 1834–1836 The South Australian Association, with the aid of such figures as George Grote, William Molesworth and the Duke of Wellington persuaded the British Parliament to pass the South Australia Act, 1834. The Act defined the province of South Australia as being "that part of Australia which lies between the meridians of the one hundred and thirty-second and one hundred and forty-first degrees of east longitude, and between the southern ocean and the twenty-six degrees of south latitude, together with all and every the islands adjacent thereto, and the bays and gulphs". South Australia thus became the only colony authorised by an Act of Parliament. The colony and its capital city were named prior to settlement. The planners and founders of South Australia called for the colony to be their ideal embodiment of what they perceived to be the best qualities of British society. They sought: to prevent a reliance of convict labour found in other colonies, thus also reducing unemployment; to eliminate religious discrimination and; to make the colony economically self-sufficient. It was intended that free settlers would be attracted on the basis of freedom in the political, economic, civil and religious spheres, as well as opportunities for wealth through farming and commerce. Hence the transportation of convicts from the United Kingdom was forbidden by the South Australia Act, despite many convicts being transported to penal settlements in New South Wales (between 1788 and 1842), Van Diemen's Land (Tasmania; 1802–1853), and Moreton Bay (Queensland; 1825–1842). (Later, convicts were also transported to Western Australia, between 1850 and 1868).
