IHL:
It is exactly the same process for a Canadian to head down under. Most under 30 get in with the 1yr working visa so they can enjoy a working holiday in NZ and OZ.
As for pilots - same hassles to immigrate but there really isn't the capacity in the industry there to accomodate foreign pilots to the equivalent numbers of antipodeans that come to Canada.
But! there are plenty of Japanese and German pilots in NZ and I know that Marty C from Airbourne spent quite a bit of time flying in the outback. Canadians are predominant in PNG as well.
Additionally there are a few canuks flying fixed wing for the likes of Quantas and other regionals.
