Be patient with Australians. They have have a terrible tradition of vicious racism.The indigenous people of Australia were only considered part of Australian society (e.g. counted in the census) in 1967. As a New Zealander visiting Australia the casual racism of white Australians is mind blowing. New Zealand is not free from racism, far from it. Australia is next level
It will take a few generations for Australians to come to terms with living on stolen land, and to adjust to being colonisers. (White New Zelanders, Pākehā have been doing this for over thirty years, it is a process)
It is odd to put that declaration on a web page, how a digital asset is comparable to standing on land is clearly something the Australians are working on. Good luck to them, move on and let it be.
