Coniston massacre
The Coniston massacre, which took place near the Coniston cattle station in the then Territory of Central Australia (now the Northern Territory) from 14 August to 18 October 1928, was the last known officially sanctioned massacre of Indigenous Australians and one of the last events of the Australian Frontier Wars. People of the Warlpiri, Anmatyerre, and Kaytetye groups were killed. The massacre occurred in revenge for the death of dingo hunter Frederick Brooks, killed by Aboriginal people in August 1928 at a place now known as "Yukurru", also known as Brooks Soak.
Mr Whoppit
Campbell was killed during a record attempt on Coniston in 1967, while driving the jet hydroplane Bluebird K7. His body wasn't recovered, although Mr Whoppit floated free and was found almost immediately by Leo Villa. Campbell's body was finally located and recovered in 2001.
