Yes, about time they gave some credit and respect to the native people of the continent. However it seems not enough considering they basically stole their land, and it sounds more like a way to lure in more tourists.
You should watch less of Avatar and Dance with wolves and use common sense more. You cannot steal "land" from under somebody, who has no concept of private land ownership. Aborigines were at no point hippies either, they were merely still stuck in hunter gatherer culture, that kept migrating.
I think the aboriginal Australians are perhaps the oldest culture in the world (50,000 years old). When the Europeans first arrived, there were around 1,000 tribes (some numbering just 80 to 100 individuals), speaking their own languages. It is very difficult to believe that these tribes numbering only a few dozen people managed to survive intact for 50,000 years.
Your scepticism is correct, while their core genetics and some customs might indeed trace its origins back to original settlers, tribal identity is quite fluid. Some of those groups might separate and merge again depending on relationships within leading family or enviromental pressures.
