TY777, before you get started down the pilot road, go and get an initial CASA class 1 medical. You would need to pay for this regardless of which path you go if you decide to fly. That way you can be ruled in or out. For instance for males colour blindness is approx 1in 8 which can be problematic. Without a Class 1 commercial aviation won't be possible, this is a show stopper. You need to visit a DAME, CASA has a
search function to find your nearest one. You should also look at the fees, further details and information:
First-time medical certificate applications. It will probably cost $1000+ for the medical, tests and fees. Annual renewals are cheaper $200~$300 if you don't need additional specialist reports. You should keep your renewal up to date so you don't need to go through a second initial application if it has lapsed.
As for the proposed QF scheme, I would not be holding my breathe. Do not depend upon any airline to deliver anything to you. You could be waiting for an eternity, or they could open applications next week. If and when it does open, it would likely have very similar characteristics to the Jetstar program:
JETSTAR CADET PILOT PROGRAM 2019. Study the document extensively, then use the PPRuNe search function get almost all the answers to your questions.
Do you intend to be a Cadet only or not at all pilot? ie is this a binary choice for you? Would you consider doing it yourself if you didn't get into the Cadet program? Between the medical and the Jetstar info, that should keep you occupied for quite some time just getting your head around the key concepts.
There is a huge amount of information on PPRuNe
The Pacific: General Aviation & Questions for someone considering this industry, learning to fly and the various pathways. I suggest you trawl there extensively, there is much hidden gold about how this business works. If you don't have contacts in the industry it will take months to begin to figure out how this pilot business
*ACTUALLY* works. Before you commit to potentially financially ruinous path, I suggest extensive due diligence before committing a cent. If you aren't ruthlessly determined and a self-directed, this business isn't for you.
Good luck with your research and decision.
