Unless you are an Australian resident, there is no point doing Australian qualifications past PPL here if your ultimate aim is JAA.
The most cost effective way to a JAA licence is:
Do the PPL and build up to 175 hours here in Australia.
Then, go to Europe and do the exams and the CPL, IR modules etc there.
No converions to do, no hassle with visas, costs a fraction of the price of an integrated course, have the holiday of a lifetime while building hours, get some real flying done ... rather than spend a fortune to on an integrated course at a sausage factory with inexperienced instructors ... because the funny "bling" uniform is really all you are paying the extra for.
