SBS advises that this program may cause distress to members of the Aboriginal and Torres Strait Island communities. It may contain images or voices of deceased persons. Commonwealth Government take charge of Aboriginal affairs, effectively acknowledging Aboriginal people as citizens within their own country. When the British government colonised Australia, they completely ignored the original inhabitants, declaring the land empty of people - terra nullius. From then on, Aborigines were treated as non-citizens and denied the rights that others enjoyed. While many people believe that the 1967 Referendum gave Aborigines the right to vote, it in fact removed two sections of the constitution which discriminated against Aborigines.
