“aborigines” is not a great word to use these days. It’s generally seen as pretty offensive to Indigenous Australians as it’s a bit dehumanising and comes from colinisers who treated people like animals.
Better to go with “First Nations people”, “Aboriginal and Torres Strait Islander people” or “Indigenous Australians.”
But yes, they’ve been treated (and in many cases continue to be treated) pretty horribly.
They ruined Linux!
