canada is a great option depending on your experiance and hrs. I know of 4 blokes recently that had to wait about 4 weeks to get there visas but they did get them. If you stick to the bigger companies you will be fine. The season is under way though so you wouldnt want to wait much longer. Becarefull how you go through customs as well the will grill you...dont carry a helmet or anyflying info post it through from OZ to a heli scholl where you do a conversion.
