> It was pointed out during one of our games this week that ‘Australian Aboriginals’ is no longer considered an appropriate term, and that we should be preferring 'Australian Indigenous peoples’ instead
I don't think this is accurate; my understanding is that most Aboriginal people would identify themselves by that term.
"Indigenous Australians" is widely used because it also includes Torres Strait Islanders -- who are Melanesian, not Aboriginal -- but who are indigenous to Australia nonetheless. They have distinct religious and cultural traditions, though, so for a question on traditional mythology there's nothing incorrect about just saying Aboriginal.
