My decision in principle states that I would also have to attend with a passport with a valid visa when completing registration, otherwise they would be registering people without the right to work I guess. I don't know the ins and outs, but I can't help thinking that, without a valid visa, your trip to complete registration will be futile and you will have to reapply to AHPRA when you are ready to proceed with your visa. Could you not start the process of applying for your visa now, and then once it's granted take the trip over to validate both registration and visa, then your visa will have 5 years on it from date of granting to re-enter, giving you time to make the move when it suits? I only know what I have been told and what my letter from AHPRA says, but I expect it's quite standard.
