Hi Stusssy,
You say the Aussie syllabus matches 100% to the JAA one, but the Aussie CPL(H) is only at most, 125hrs and that is without a fixed wing PPL.If you have a PPL it drops to 70hrs.
The JAA requires from memory is 155hrs before you can do the 30hr JAA course which will include Instrument & Night time.Then of course the written subjects and from what I understand they are no mean feat themselves.
In my opinion after coming to Aus myself(5 Years ago) to train I would go for the Jaa option probably via the states.This would give you more chances of working around the world purley on the basis that the JAA licence is probably the most easily converted to other licences.
Good luck with your choices,
Nick
