I'm Australian but have lived in Europe for a long time. When I begin to consider moving back, one of the things that puts me off is that 4 weeks is pretty much universal in Australia, plus in Australia I think it's pretty standard to have a fixed number of days you're allowed to be sick. I'm too used to having 6 weeks holidays and essentially unlimited sick leave (as long as it's legitimately required).

It's a more grown-up arrangement where businesses realise that regular time off (and as much time as you need if ill) increases happiness and therefore productivity.

I still miss the food at home, though.
