JAR Lic.
Bad news for you I'm afraid. Your ATPL counts for nothing towards a JAR ATP. We have a number of guys here at work studying JAR now, including an Aussie, and they have to do all subjects for the theroy again. (13 in all I think). There is also limits as to how long you take to get all the credits.
Up until recently I believe there was an avenue to convert using some of the European and the New Zealand licence, but that door has closed.
But all is not lost. I understand that there will be a recognition of ICAO licences soon.
Time will tell. The unfair part of all this is that a JAR coming to Oz sits one 'conversion' exam and is issued an Aussie ATPL. Well what I mean is that that is fair, going the otherway isn't.
Good luck with your studies, keep at it.
