My general impression is that Australians vary between neutral (they don't know and don't care what he did) to positive toward him.
Where I live (way out in the boonies), many people have told me that they have a lot of admiration for him. In some spaces in Melbourne, he seems to almost have a cult following.
I am sure he has his detractors in Australia but, so far, I have either not met any in person or they have kept their opinions to themselves.
I think politicians are more likely to dislike him than the general public does, which makes sense; after all, he targeted politicians and policy decisions.
