One problem for all integrated courses is that HECS of FEE HELP is limited to $96,000 (from memory). Not many students seem to get thru the integrated courses in the minimum curriculum times, and I've known a few to need an extra $30,000.
My son did his PPL as a medium-sized GA school, which I paid for. This got him into an integrated uni course and means he should be able to finish his CPL, MECIR, Instructor Rating and ATPL theory within the $96,000. This is good for me because it takes a lot of financial pressure off me.
I've been very impressed with the integrated uni aviation course he is doing, but I think the Jetstar cadetship would also be a good option.
Part of the Low Cost Carrier model (such as Ryanair and and Ezyjet) seem to include the same type of pilot cadetship that Jetstar are now offering. At least here we have FEE-HELP/HECS, which saves the parents having to mortgage their house.
