In addition to TINSTAAFLs post, if you just do PPL and hour build here, (forget getting all sorts of Aus quals which you only need if you will be flying commercially here) then go to JAR land for modular, there is in fact nothing to convert (you can fly there on an Aus PPL then go straight to JAR CPL) and associated costs, or repeating things.
Pilot In Command time is what so many people lack, and Aus is a great place to get it and have the holiday of a lifetime in an aeroplane; get some REAL experience rather than being spoon fed an expensive integrated course.
(FWIW I have CAA and Aus CPL).
