To work as an occupational therapist in Australia, you need to apply for and be registered with the Occupational Therapy Board of Australia. You may also need to apply for a visa issued by the Australian Department of Immigration and Border Protection (Australian Immigration Department).

These two application processes are entirely separate and success in one does not automatically guarantee success in the other.
