To practise in Australia, you need to apply for and be successfully registered with the Osteopathy Board of Australia.
You may also need to apply for a visa issued by the Australian Department of Immigration and Border Protection. Osteopathy is on the Skilled Occupation List, which is used for 457 (Temporary Work Skilled Visa), 189 (Skilled Independent Visa), 489 (Skilled Regional Provisional Visa) and 485 (Graduate Temporary Visa) visa applications. These two application processes are entirely separate and success in one does not automatically guarantee success in the other.
New Zealand Osteopaths
If you are a New Zealand osteopath who holds current registration and an Annual practising certificate, you can apply for registration as an osteopath in Australia under the Commonwealth Trans-Tasman mutual recognition act 1997 (TTMR).
Check the Osteopathy Board of Australia site for more details or use the Application for trans-Tasman mutual recognition as an osteopath - ATMR-56 form

Other Overseas Osteopaths
All other overseas trained osteopaths will need to undergo an assessment of their skills and qualifications. The assessment is conducted by the Australasian Osteopathic Accreditation Council (AOAC).
AOAC conducts initial desktop assessments and advises candidates whether they are eligible to be assessed by the Osteopathy Board of Australia via one of two pathways: the 'standard pathway' and the 'competent authority pathway'.
Please read the AOAC guide for Qualifications & Skills Assessments.
Depending on your eligible pathway, your steps may include:
Written paperwork assessment
Practical clinical exam
Open book exam
Assessment (open-book) on Information on the practice of Osteopathy in Australia - A guide for graduates trained overseas
Supervised practice under provisional registration for a minimum of six months
