Hi,
TTMR = Trans-Tasman Mutual Recognition; as a NZ registered Physiotherapist you are eligible to apply for registration in any of the Australian states; as an Australian registered Physiotherapist, you are eligible to apply for NZ registration under that act.
Find a list of all Australian registration boards here:
Australian Physiotherapists Registration Boards —
You still have to undergo the registration process though, but it's really easy.
Regards,
