60, passed 31 July 1838) incorporated the changes. Afterwards The first migrant ship, the John Pirie, set sail for the colony three days later. On 28 December 1836, Governor Hindmarsh issued a Proclamation of the new Province at Glenelg. On 31 July 1838, the changes were brought into law by "An act to amend an act of the fourth and fifth years of his late majesty empowering his majesty to erect South Australia into a British province or provinces" (short name ascribed by the National Library of Australia: South Australia Government Act 1838), 1 & 2 Vic, c. 60. Significance to Aboriginal people As colonisation proceeded, no heed was paid to the words of the Letters Patent about Aboriginal rights to land: there were no treaties signed; colonists bought, leased and were granted land, thus effectively dispossessing the original inhabitants of their land. In 1966, Premier Don Dunstan passed the Aboriginal Lands Trust Act 1966 on the basis of the unfulfilled Letters Patent, which gave rights to Aboriginal people over their land (later enshrined in the South Australia Government Act 1838). From the early 21st century, research focused on the potential legal implications of this disregard of the Letters, and the document again became a source of debate. On Proclamation Day in 2006, the then SA Minister for Aboriginal Affairs, Jay Weatherill, acknowledged publicly that the failure of the state to have met the Letters' promise 170 years later has "been the cause of much loss and suffering for Aboriginal people". On 24 April 2007 the Australian Democrats MLC, Sandra Kanck, and Greens MLC, Mark Parnell, on the occasion of the Sesquicentenary (150 years) of Responsible Government in South Australia referred to the Letters Patent when they read a statement authorised by the Aboriginal Alliance Coalition Movement in Parliament, "asking you to acknowledge that your enjoyment, if not the spirit, of your commemorative congratulations, blindly overlooks the denial of our English land rights within our own country in establishing your parliament on the land of the traditional owners and on the country of their unacknowledged descendants". The 175th anniversary of the Letters Patent was commemorated at the Living Kaurna Cultural Centre at Warriparinga on 19 February 2011, as a document which preserves the rights of the Aboriginal inhabitants. The 2014 film King's Seal tells of the struggle for recognition of rights that were granted by the Letters Patent. 2018 Kaurna
