The heritage listing of the site is part of a longer term trend in which one aspect only of race relationships in colonial Australia is recognised, namely white violence toward Aborigines.
I spent a number of years reading colonial era newspapers and it gave me a fuller picture of the reality of the era. The most common attitude of white settlers toward Aborigines was one of curiosity, particularly about Aboriginal language and customs.
As for violence, the situation was more complex than is usually recognised. Yes, there was violence by whites towards Aborigines on the newly settled frontier. But there were also occasions when whites helped to prevent violence between different groups of Aborigines. There were some Aborigines who helped rescue white settlers. There were other Aborigines who murdered white settlers.
The last point usually baffles those white Australians I mention it to. They find it a difficult thought to process as they are so used to the idea that violence went the other way. So I'll give just a few examples of Aboriginal violence toward white settlers to help illustrate the situation.
In colonial Tasmania, in the short period of time between January and October 1828, there were 68 separate attacks on white settlers by Aborigines, resulting in 26 European deaths (including women and children).
The records of the Adelaide Gaol show that between 1843 and 1861 there were 12 hangings, all for murder. Of these, three were cases of violence between whites. Of the other nine, only one was a case of white violence against an Aborigine. The rest, the large majority, involved Aboriginal perpetrators and white victims. There were 10 white victims altogether (5 men, 3 women and 2 children).
After one of these hangings of an Aborigine for murdering a white, a newspaper editor used the occasion not to demonise the Aborigines, but to express doubt about the use of capital punishment:
If transportation for life is the full penalty in England more ought not, we think, to be inflicted here...
The above list of white South Australians murdered by Aborigines doesn't include the victims of the Maria massacre. In June 1840 the brig Maria hit a reef; the passengers and crew were evacuated safely in a life boat. They negotiated with a local Aboriginal tribe to escort them back to Adelaide; however, this tribe wouldn't go further than their tribal boundaries. The shipwreck survivors were handed over to the neighbouring tribe who massacred them, stuffing the bodies down wombat holes.
Twenty-five white settlers were killed in the Maria massacre, including five women and six children.
There has been a filtering of Australian history which has created a false picture of the times; there is a one-sided account of race relations in which it is only white violence against Aborigines that is recognised and in which only the most negative and unsympathetic of white attitudes toward Aborigines is publicised.
