I agree with training wheels.
Try Qlink. You could be on the 400 in CB fairly soon, and if you can stand it there, could get a 400 command well within three years. Be aware that CB -SY -CB all day every day can wear thin.
Good luck with jumping through the Qantas hoops. You may find them a little bit more flexible now. I think your experience will help a lot with the lack of currency. Have a look at the Qlink traineeship threads and links.
