I'm a brain-drainer - born and bred in Perth, but well and truly never lived in Australia. As soon as I could, I left .. and every time I return, it is as a tourist.
That said, I hope there are some houses left to buy, at the end of a long dusty road, next to a beach or two, some day in the future. Would be fun to return when the madness is over (i.e. Australia gets real Internet, &etc.)
