Well here down under we have a massive shortage of skilled and unskilled workers, numbers of immigrants is going to be seriously upped very soon the Gov have announced, there are more job vacancies than people on the dole.
So you can all come here :). Yes we do have a public health system called medicare for which we pay 1.5% of our wages.
It's winter here, Darwin today is 31deg... Cairns 28deg...Brisbane is 22deg... Sydney 18deg... Melbourne 16deg... Hobart 14deg so you can see the further south you go the cooler it gets BUT, nobody is freezing their balls off. :)
Plus the state Gov will pay a lot towards your solar panels on your roof, being as there are lots of sunny days you can sell leccy back to the grid !!!
