This article on Greeks seeking refuge from their woes by emigrating to Australia is a bit old now, although I would be very surprised if the desire to go has changed at all. Greeks are now, by one measure I saw, the seventh largest ethnic grouping Down Under.
Of course, countries such as Australia and Canada, for that matter, might not be as easy to emigrate to as in the past if the would-be emigrant does not have the sort of skills that are likely to appeal to any granters of visas. And without wishing to sound sour about it, I could argue that the sort of enterprising Greeks who would have been welcomed with open arms by such countries have left their ancestral homes long ago. Another problem is that the very people who are trying to get the hell out of Greece are likely to be the sort most likely to drive their country back towards some semblance of prosperity.
Update: EU officials are starting to admit they are planning for a Greek exit. The end of Greece’s eurozone membership is very close now, I think.
