This is an interesting read. It does not refute the indigenous claims of prior custodianship of australia but does indicate that the aboriginals were maybe not the first nor the last occupiers of Australia.
At least the white occupiers did not wipe them out despite initial attempts and have made some serious efforts to engage and incorporate them in the modern society, at least in more recent history that is.

Maybe the current protestors should just accept that history changes and joint in those changes.

Evidence of pre-aboriginal Australians?
