Governor of South Australia

The governor of South Australia is the representative in South Australia of the Australian monarch, currently King Charles III. The governor performs the same constitutional and ceremonial functions at the state level as does the governor-general of Australia at the national level. In accordance with the conventions of the Westminster system of parliamentary government, the governor nearly always acts solely on the advice of the head of the elected government, the premier of South Australia. Nevertheless, the governor retains the reserve powers of the Crown, and has the right to dismiss the premier. As from June 2014, Queen Elizabeth II, upon the recommendation of the premier, accorded all current, future and living former governors the title 'The Honourable' for life. The first six governors oversaw the colony from proclamation in 1836, until self-government and an elected Parliament of South Australia was granted in the year prior to the inaugural 1857 election.

The first Australian-born governor of South Australia was Major-General Sir James Harrison (appointed 1968), and most subsequent governors have been Australian-born. The first South Australian-born governor was Sir Mark Oliphant (appointed 1971), and the first Aboriginal governor was Sir Douglas Nicholls (appointed 1976).

The current governor is diplomat Frances Adamson who was sworn in at Government House, Adelaide on 7 October 2021, replacing Hieu Van Le, who held the role from 2014 to 2021.

The governor's official residence is Government House, in Adelaide, the state's capital.
