Answer:
Australia's original inhabitants are commonly known as indigenous Australians, Aboriginal people, or as Aborigines. The latter term is regarded by many descendants of the first Australians and by others as derogatory in nature, along with the offensive slang terms 'Abo', 'Boong' and 'Coon'. The term 'First Australians' ( which is also a documentary series on the history of Aboriginal Australia) is also in use.
There were no Americans there. The natives of Australia were called aborigines, from the Latin for 'from the origin'.
