Coniston massacre
The board sat for 18 days in January 1929 to consider three incidents (Brooks, Morton and Tilmouth) that resulted in the deaths of Aboriginal people, and in one more day, finished its report, finding that 31 Aboriginal people had been killed and that in each case the death was justified.
Cape Grim massacre
On 10 August Robinson encountered convict William Gunchannon, another of the four who had been present at the massacre. Gunchannan admitted his involvement, estimating it had happened about six weeks after the destruction of the sheep, but was reluctant to provide detail. He told Robinson that the Aboriginal group attacked on 10 February had included men and women, but denied knowing whether any had been killed. Robinson later wrote that when he informed him that Chamberlain had already admitted a death toll of about 30, Gunchannan "seemed to glory in the act and said he would shoot them whenever he met them". Robinson did not interview the other two involved in the massacre: Richard Nicholson had previously drowned and John Weavis had since moved to Hobart.
