lastdon, be aware that an Australian license is neither an EASA nor FAA license. It is a completely standalone beast. Therefore, if you later on decide to fly in Europe and/or the US you will have to jump through some more hoops to gain eith an EASA or FAA ticket. One alternative could be to finish your PPL in Oz in an EASA school.
AFAIK there are a couple, though not many. In any case, while the actual flying of course is the same - the laws of physics apply even when inverted Down Under
- the airspace and procedures in Oz are significantly different from Europe or the US.
In any case, the people you have to talk to are CASA in Oz. Good luck.
