Why Australia Hasn't Taken a Populist Turn to the Same Extent as the US or UK?

I think there's a broader appreciation of the fact that house prices could fall and could fall by quite a lot. And you may find yourself in negative equity territory, having to sell a house and recover less than what you are the bank. I mean, that's not part of the Australian mindset. That's still why it hasn't happened so far. Why hasn't Australia taken a populist turn to the same extent as the US or UK? The jury's still out. Do you have any explanations?
