I’m not going to claim to be an expert on this, the rules are changing frequently enough for this information to go out of date quickly, especially as most car ‘regoing’ (The Australia term for registering, taxing and insuring a car all in one package) are going to online regoing.
Check the current state websites for the latest rules, however if you are in Australia and want a difficult life by registering a vehicle in your name from a different state, I advice going down the local licencing place and asking, it is by far the quickest and clearest way to know what you need too.

My experience is bringing a private use vehicle from NSW to WA. As it turns out, it doesn’t really matter which state you are bringing it from, it matters where you are bringing it too, and that’s the licencing authority you want to deal with.
The rules to date (December 2009) on bringing a interstate car to WA (this doesn’t apply if you’ve owned the car for 12 months in a different state amongst other requirements), is it must pass a vehicle inspection to confirm it’s roadworthy-ness, and along with proof of ownership, you go to registry office (with your ID too of course) and get the new plates and registry in your name.
I hope that helps someone, but as I mentioned, it’s best to get the official word early on, or just make your life simple and buy a car in the state you currently are in.
