As for moving to Perth to work, the local newspaper is running a blog at the moment about that very subject. There's a lot of rubbish on there and it seems everyone has an opinion, it's the general public there though and they don't seem to be considering the kiteboarding conditions. That was a big drawcard for me when I decided to leave my extended family behind on the East Coast and move here. Between kiteboarding and the fact that I'm a mining professional Perth is so perfect for me that I really can't imagine living anywhere else.
One thing a lot of people mention and I have noticed too is that Perth can be quite cliquey. It has been suggested that because it is so isolated from the rest of the world that Perth locals are an isolated sort of people, they don't seem to want to become friends with new people once they establish a network through school and family. Again this is the general public and does not take into account the kiteboarding factor. There's a decent group of kiters here who are reasonably sociable and in fact I feel more a part of a community here than I have in a lot of the places I've lived since I left my home town.
Anyway the blog is here:
