Mach is right about the snagger factory comment!
Give the REX road a big miss! QF is good if you get in.
Swan TAFE run an ATPL course for a FRACTION of the cost. Takes a year, diploma at the end. And you have a few days off to do your flying. ATPL stuff is done by Rob Avery himself so its good quality! If you wish to continue to Uni you get 1st year exemption at ECU.
Any diploma in aviation is realistically worthless, its command hours that matter!
Never pay upfront, good sign their cash flow river is pretty dry!
