 The South Australian Company ended business in its own right on 17 March 1949 when it was liquidated by Elders Trustee & Executor Company Ltd, which had been managing its Australian affairs since the death of the last Colonial Manager, Arthur Muller in 1936.The formation of the company followed considerable lobbying by the South Australian Association, a group consisting of philanthropists, radical thinkers, dissenters and merchants.After a years of negotiation, false starts, changes and amendments to suggested charters, the British Parliament finally gave approval and passed the "South Australia (Foundation) Act" on 15 August 1834.
