I was there between 89 and 92, the open racism toward any non white non Australians was truly awful, the racism toward the aboriginal people was absolutely shocking and abbo was not the usual word used by many, I’m sure some will know the word I mean.
Spent months up in the Kimberley and the Northern Territory, the worst thing by far was that some of the hotels (pubs) had segregated bars, not officially but they would have two bars and aboriginal folk weren’t allowed to go in to the nicer bar, if they did they’d be asked to leave, I saw this happen and the person was told “Your bar is next door.”
I imagine things have changed greatly since then, I certainly hope they have.
