If that is 20K pounds, then it is certainly possible. If you go by the PPL - hour build- upgrade to CPL route. You pay less, and come out with more hours than going to a glossy integrated course which will cost twice as much for less hours. And the amount of time it takes is completely up to you. Plus all previous flying you have done will all count on the upgrade course - not always the case with an integrated course who may only credit you with the minimum requirement for any licence you hold. (eg 40 hours for a PPL)
Anyhow unless you are planning to fly commercially here, for which you will need Aus residency as a minimum, there is no point doing the Aus CPL/IR here as you will need to repeat so much of it back in the EU. Why do all that work and spend all that money twice?
You can do the JAR course here, though some parts of that still have to be done back in the UK, and it is an expensive option, costing about twice what it would cost you to do PPL and hour build here then CPL, IR Exams etc back there at a school of your choice.
