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.
St. Brice's Day massacre
Historians believe there was significant loss of life, though evidence is lacking on any specific estimates. Among those thought to have been killed is Gunhilde, who may have been the sister of King Sweyn I of Denmark. Her husband Pallig Tokesen, the Danish Ealdorman of Devonshire, may also have died in the massacre or, according to a different version, played a part in provoking it by his defection to join raiders ravaging the south coast.
