Hi Angela here, I will talk you through the whole process. I emmigrated from England 17 months ago to Australia. I sat the written exam in London in March 05 and the practical I did in Adelaide in October 05. We came to the Northern territory(Alice Springs to be exact) because they have a 'Health Practitioners act" which enables you to work as a physio for a year on a temporary registration. This meant that I could get a temporary visa and be in the right country to do the practical exam (which has to be done in Aus). My employer business sponsored me and I signed a contract for 2 years.
I think it was worth it all (expense and revision). I have a very rewarding job and a very appreciative employer!
Hope this helps
