I'm curious which population in Australia you are designating as "indigenous". Here in the UK, "indigenous" usually means white. But I think of indigenous Australians as the aboriginals.

So there's history in Australia of white immigrants trying to force aboriginals to "integrate" with whites. I suppose you could call that "targeted diversification". But you make it sound as if your social circle is white people, objecting to "diversity" in the sense of deviation from whiteness.

Would you mind clarifying?
