This is a very broad question. What are you interested in?

Land rights is probably the most different between Australia on one hand and Canada and NZ on the other hand. There was an academic debate about a doctrine called "terra nullius" which was applied in Australia but not in the other countries, which meant that the Europeans didn't acknowledge native ownership of land at all. There are no treaties in Australia.

I'm not as familiar with Canada, but the status of Maoris and treatment has been significantly better than treatment of Australian aborigines. No commercial fishing rights, stolen generation, effective genocide in many areas, embarrassingly horrible health problems, life expectancy worse than many third world countries.

Not an answer to the question, but the generally preferred nomenclature for Australian Aboriginals is Aboriginals (or even better, the Aboriginal Peoples). "Aborigines" is generally disliked as an antiquated term applied to them semi-similar I guess to calling black people in America Negroes (but I don't think quite so looked down upon as that would be).
