There have been a number of documented conflicts that resulted in mass deaths of Aboriginal people throughout the continent, now sometimes referred to as "
frontier wars". In South Australia, the government tried to strengthen laws in an attempt to avoid the violence that befell earlier Australian settlements, and Aboriginal people were declared British subjects and afforded the same privileges. However, the laws were rarely enforced, and as the frontiers of settlement spread, dispossessed Aboriginal people responded with aggression. In July 1840, there was a massacre of Europeans by Aboriginal men in South Australia, when about 26 shipwrecked passengers and crew members of the
ship Maria were murdered. The ship had run aground somewhere in the southern
Coorong and all aboard made it safely to shore. They were initially assisted by the Ngarrindjeri people, until a misunderstanding or disagreement led to the murders. A punitive expedition was mounted by
Governor Gawler, who gave permission to execute up to three suspects without formal trial.
Major O'Halloran carried out the order. In 1841, at least 30 Aboriginal people were killed in an incident known as the
Rufus River Massacre, after a series of skirmishes in the Central Murray along the old Aboriginal route recently made into the overland
stock route. A party of which included police and the SA
Protector of Aborigines,
Matthew Moorhouse, and
overlanders bringing cattle to market in Adelaide from New South Wales, became involved in a clash with the local
Maraura people. Although the location
was and still is in New South Wales, not South Australia, the official party was sent out from Adelaide on the orders of the
Governor of South Australia, the newly appointed
George Grey. The traditional lands of the Maraura people stretched deep into South Australian territory. In 1848, at least nine people of the Wattatonga clan (of either the
Bungandidj people or
Tanganekald people) were allegedly murdered by the station owner
James Brown in the
Avenue Range Station massacre (near
Guichen Bay on the state's
Limestone Coast). Brown was subsequently charged with the crime, but the case was dropped by the Crown for lack of (European) witnesses. Christina Smith's source from the Wattatonga tribe refers to 11 people killed in this incident by two white men. In 1849 at least ten
Nauo people were killed in retribution for the killing of two settlers and the theft of food, in the
Waterloo Bay massacre at
Elliston on the west coast of
Eyre Peninsula. ==Settlements==
