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.

It was claimed by Royal Ulster Constabulary (RUC) Special Patrol Group (SPG) officer John Weir, that the UVF killers were Robin Jackson (who was also allegedly involved in the 1974 Dublin car bombings as well as a series of sectarian killings), Robert McConnell, and Harris Boyle. The men, including Weir, were all members of the Glenanne gang, which was made up of rogue elements of the RUC, Ulster Defence Regiment, regular British Army, and the UVF Mid-Ulster Brigade. These allegations were published in the 2003 Barron Report, which was the findings of an official investigation of the bombings by Irish Supreme Court Justice Henry Barron. In the same report, Weir claimed that he had received information from an informer that British Army captain Robert Nairac was also involved in Green's killing. The 1993 Yorkshire Television documentary "The Hidden Hand: The Forgotten Massacre" states that Robin Jackson and his UVF comrades were controlled by Nairac, who was attached to 14th Intelligence Company. Secret Intelligence Service operative Captain Fred Holroyd also asserted that Nairac had executed Green, who was, according to Holroyd, commander of the Provisional Battalion of North Armagh. Captain Holroyd claimed that Nairac boasted about the killing and had shown him a colour polaroid photograph of Green's corpse taken after the killing. Holroyd also told the Garda Síochána that he had received a photograph of Green some months prior to his killing. Holroyd enlarged the photograph and had it distributed. He believed from that time until Green's death, 4 Field Survey Troop, one of the three sub-units of the 14th Intelligence Company led by Captains Nairac and Tony Ball, had Green placed under surveillance. Nairac's claim has been discounted by two Garda investigations which revealed that the polaroid was one of a series taken of Green's body by a Garda officer the morning following his fatal shooting.
