Massacres of Indigenous Australians span our country, both in time and place. Starting in Sydney, the last recorded massacre was in 1928, the Coniston massacre. ( see http://en.wikipedia.org/wiki/List_of_massacres_of_Indigenous_Australians ) Only one was brought to justice, at Myall Creek, and even then it can be argued those who were hung were only convict scapegoats. The one squatter involved was not brought to trial.
Whilst the AIM does not pursue specific policies, some members of AIM are working towards an apology for the massacres, starting in the state where they started – New South Wales.
