I lived and worked in Perth and that is mostly true... almost half the city work in some mining related thing. But come on... Perth was a pretty small 15 years ago for what I've heard and it has become one of the best places to live in the planet thanks to mining. So I don't think you can complain about it. If you go to Sydney or Melbourne there are lots of other job options.
