There is no other place on this planet I would rather live. And I have seen many places all around the world.
I've been gone 6 years now and still miss it, but it is changing very quickly (I guess everywhere does if you're not there).
Things have become really expensive. I have friends who are pretty much running on a mousewheel just to stay afloat, financially. Their quality of life isn't great.
And as much as I love the aussie personality it really seems like every time I go home, people have become just that little bit more aggro. Idiots on the road who think it's cool to drive aggressively, guys punching on in the middle of the street...I saw 2 fistfights and 2 near accidents caused by road ragers in a week at the start of the year. And I wasn't out much.
And it seems impossible to live a normal life in Australia now without having a fucking smartphone glued to your hands.
