Old Government House is a historic building located in Belair National Park, South Australia. It was the summer residence of the Governor of South Australia from 1860-1880, and was used by governors Richard Graves MacDonnell (1855–62), Dominick Daly (1862-68) and William Jervois (1877–80). It is now a tourist attraction and is open to the public on Sundays and public holidays.
Old Government House was South Australia’s first official vice-regal summer residence. It was constructed from local sandstone, with the red-brick for the quoins sourced from the Blackwood brickworks, and a native timber shingle roof. The residence's indoor plunge-pool was reportedly the first in the colony.
It was superseded by a larger summer residence at Marble Hill, completed in 1880. It was then used by the curator of the Department of Woods and Forests Nursery (also located in Belair National Park) until it was transferred to the National Parks and Wildlife Reserves in 1961. Minor renovation work was carried out and the building was opened as a museum. More extensive renovations in the 1970s and again in 2002-03 restored the building to its original grandeur.
Old Government House is now cared for by the Friends of Old Government House, a member group of Friends of Parks Inc.
Within a few years of the settlement of South Australia, the colonial government decided to establish a "Government Farm" for the purpose of agisting horses and bullocks, and providing hay and fodder. The area chosen was the upper reaches of the Sturt River; In addition to its suitability as farmland, governor George Gawler thought the area would be ideal for the establishment of a summer residence. In July 1840, in a highly irregular transaction, thirteen surveyed sections of 80 acres (32 ha), plus 1,000 acres (400 ha) of rough country to the east were purchased. The sale was dubious in that it was paid by private promissory note, rather than through official government channels. Additionally, the sale document did not mention three of the 80 acre sections, nor the large section of rough country. When Gawler was replaced by George Grey in May 1841, the colony's finances were in considerable debt. As a fundraising measure, the newly established farm was offered for public sale. However, realising that their title to the land was dubious, the government cancelled the sale. Ironically, the government's questionable title to the land ensured it remained in public ownership.
