You've been unsurprisingly downvoted, but there's some truth to what you say, as long as 'typical' is parsed as 'stereotypical' rather than something more mathematical. Anyone who has spent any time in Australia knows the type well.

My guess however is that the stereotype represents a shrinking proportion of actual Aussie males, though they're still there. We all have our own selection bias of course, but in my experience young Australian men are a pretty big improvement on their bald barrel-shaped shock-jock-addled beer-guzzling 4WDing [poofter/boong/woman/asian/tree/whatever]-hating coal-loving fathers who so despoil the Australian suburban landscape.
