ra-aus to ppl
I'd suggest Dexta's advice is spot on. When CASR Part 61 becomes effective (Sept 2014) you can obtain a Recreational Pilot Licence (RPL) by producing your RAAus Quals to CASA. An RPL allows you to operate GA aircraft below 1500kg MTOW and carry yourself plus 3 pax (with a class 2 medical). You'll need to complete a GA flight review before you can exercise the privileges of the RPL. If you get up to speed with the skills outlined by Dexta you might find a check out in a C172 plus some procedural training will see you flying GA without needing to sit any exams. You can gain experience in GA aircraft, the PPL theory, complete a pre test, further training if required and a flight test to gain a PPL at your leisure, if you choose to. The PPL will allow you to fly more complex / heavier aircraft and gain night / instrument ratings if that's what you'd like to do or you might choose to stick with the RPL.
