Australia recognises BASI's Alpine, Snowboard, Nordic and Telemark qualifications and each snowsport school has its own employment requirements. As a general rule, only qualified instructors will be offered work, usually at 'hiring clinics' held in May each year - and you'll need to register before attending. There's useful information and good contacts at the Australian Professional Snowsport Instructors website www.apsi.net.au
For example of individual resorts and application forms, go to www.perisherblue.com.au
Applicants are usually expected to provide their own work permit (or 'working holiday maker visa') and you can't apply for a 'hiring clinic' until you have one, unless prior arrangement for sponsorship has been made through an individual snowsport school (e.g., Perisher). The visa program is designed for travellers to Australia to both visit and work to sustain their travel. The visa is valid for 12 months and, normally, you can only work for one employer for up to 3 months. Check out the Australian immigration website www.immi.gov.au for more information and online applications.

Please Note: Working independently, regardless of qualification, is not permitted under Australian law.
