And affectionate slang would be "pommie <c-word>" - or, at least, that's the impression I get as a pom! :)

As an Aussie, that c-word thing isn't really a thing in my experience, at least not in the urban environments I inhabit. (It may be a thing in the bush.)

We tend to be "direct" and generally have no fear of speaking truth to authority: the whole "OMG we can't indict the former President" issue with Trump is confusing down here: politicians and people in positions of responsibility are held to a HIGHER standard of behaviour, not lower, and they'd be the first to be tapped on the shoulder (or we expect them to be, and would be asking why they haven't been yet).

Not sure where you're from, but in my Australian suburban jungle, cunt is a pretty common term.

You don't say it if you're over at mums for lunch on a Sunday, but hanging out with the boys? For sure.

"What's with this cunt?" etc is common venacular.
