Nah, it's pretty big for a country town, but pretty small for a capital city.
When I first went (for UWA interview) I got bored in their CBD after about half an hour. There was simply nothing to see. But after my interview my cousin's wife took me to their place and it's very nice. I say it's an excellent place to raise a family - little to no pollution, large, cheap plots of land, excellent lanscape (eg swan river) and a Go8 university to look forward to.
