Hi Lynn,
There are a huge number of vacancies within Australia. I would advice you to contact the major hospitals in the larger cities to gain info about their rehab services and potential job prospects.
I would also advise you to contact the Australian High Commission or Immigration Department re: visa prospects. Some hospitals may be able to sponsor you across, commonly for a 2 year period.
You will also need to contact the registration board in the relevant state to gain physiotherapy registration which is required before you can practice.
I hope this information helps.
Regards,
Liz BUCKMAN
