I feel obligated to provide some context here.

Australia certainly is, like most countries, “deeply racist” but exactly what that means and how we compare to other countries is contentious.

Calling immigration detention facilities “concentration camps” is disingenuous and has connotations that dont apply. At last count in 2021 there were 107 residents, all of whom could leave at any time, and were provided multiple resettlement options outside of Australia.

There are criticisms to be made but they are not “concentration camps”.

The fauna thing is an obvious myth that doesn’t withstand a moments critical though. There’s a more comprehensive rebuttal here:

Australia does have deeply embedded tensions around race. They’re not easily solvable problems. Are more salient example might be the recent rejection of the voice referendum, but that would take more than a few moments to read and understand.
