I've been to all of Australia's mainland capitals (sorry, Hobart). I've lived for long periods in Darwin, Sydney and Perth.<p>I prefer Melbourne to Sydney based on the time I've spent in each. Melbourne seemed a bit more cosmopolitan, the people a bit less artificial.<p>I'd rather live in Perth than either, but the startup scene here is quite anaemic. You can round up some geologists and raise tens of millions to do some mining exploration; but raising a few thousand for a startup is, from what I've heard, nigh on impossible.<p>I prefer Darwin most of all, but it's a government town and FIFO base. There's some IT service outfits but that's it.
