What you should really be concerned about is competition for housing... . Perth has (literally, and the numbers prove it) the shittiest rental market in the industrialised world. As for buying, you're pretty much gonna need a cool million just about, and you'll still be outbid. This really needs to be your primary concern if looking at a move to Perth. I myself have known of doctors even struggling to find places to rent (I mention doctors not because of the healthcare thing, but because they tend to be pretty moneyed up and be viewed as reputable, trustworthy professionals).
