The one closest to Ballarat was at Maiden Hills in the 1830s
The full details below:
Assistant Protector Sievwright arrested William Allan, overseer on H.B. Bowerman's run at Mt Mitchell, and two convict shepherds, Adam Braybrook and John Davis at the Learmonth brothers' station at Burrumbeet, for killing and then burning 6-8 Aborigines and taking "every pain" to obliterate all traces of the bodies. The site was on the junction of two creeks, 12 kilometres from Bowerman's outstation. Sievwright found a small piece of cranium as evidence. He also reported that several huts in the district, including that occupied by William Allan, had Aboriginal skulls placed over their doors.\nDavis and Braybrook were committed for trial for the killings. However, in the absence of corroborating evidence, the attorney general J.H. Plunkett, was unable to prosecute the two men for anything other than the misdemeanour of burning the bodies, and the men were acquitted.\nThe Rev. Joseph Orton presented the following summary of Sievewright's report.\nDated 17 April 1839:\nAllen, the overseer to Bowerman, had instructed the shepherds at the outstations to inform him immediately any natives made their appearance that he might be prepared for them. On one occasion the natives did come and were quiet and friendly, but the servants having received peremptory orders from Mr Allen to inform him when the natives came, they accordingly did so. Allen immediately ordered his horse to be saddled and rode in search of them and found the natives a few miles from the shepherds' station and warned them not to come near the station. (This incident relates to the massacre of 10-14 Aborigines being killed in July 1838.)\nAllen left orders again with the shepherds not to allow the natives near. The men, however, said they were peaceable and they were desirous to keep on good terms with them. A short time after this the blacks came to the shepherds hut and under suspicion that they came to rob the hut an affray commenced and from six to eight Aborigines were shot by the white men. The bodies were burned the next day. It appears in the deposition that a native woman was in the hut with the white men. In answer to a question Allen acknowledged that he had ordered the men to protect themselves. Davies, a prisoner, shot most or all.\nThe above is the substance of the depositions and admissions of the implicated parties which is of course the ex parte statement. Allen was bound to appear when called for in recognisance of $200. In this case nothing more has been done than taking the depositions of the aggressors and murderers. There being no evidence but their own and that of the Aborigines in the former case the accused cannot incriminate himself in a court of justice and in the latter Aboriginal evidence is inadmissible. Thus these miscreants elude justice and boast in their foul deeds which accounts for the apparent frankness of their depositions (Orton 1841: January 12).
