Bit dramatic.
I'm not talking about kids travelling though, I'm talking about folks in their 40s who have built a life over here through work, not backpacking, who wouldn't go back to Australia - or people married and looking to start a family.
As I say, I think there might be an element of the grass is always greener, both ways. But ultimately for me, it'd feel a bit too flung to the far reaches of the world, with a climate that I'd mostly not like and too far away from family and friends.
