Not sure if I can help with this one, but I heard that WA did not sign the Trans Tasmanian Deal which allows automatic registration from NZ Physios.
On another point, can you let me know how difficult it was to register for NZ Physio council? I am trying to do this to access entrance to Oz as it seems doing it through Oz physio council leads to approx. 60% failure rate. Apparently easier and cheaper through NZ. It looks like a lot of paperwork, but i would be interested to see how you went.
Regards
Pete
