Family friends of ours(the whole family) migrated to Canda about 10 years back. The parents thought it was extremly cold(they were basically from south india which is more or less tropical). The kids did their college education there and love it there but the family is back in India although the kids are canadian citizens now and want to return.

The dad was working in Qatar Petroleum for at least 15 years before they migrated so they must've saved a lot of money before they went.

Upto you dude. I donno abt australian though.
