Hi Dave,
I moved to Melbourne about 9 months ago and went through the NZ route. There are no limited registration jobs anywhere near where you would consider living over here. In my experience the only places that offer limited registration are nursing homes and small private practices in the middle of nowhere (and even they are few and far between). Unfortunately there's just too many physios wanting to work in the big cities so most practices can take their pick. I'd recommend the NZ route, it's time consuming but doable and once you have registration it's easy to pick up a job almost anywhere.
