I can't agree that instructor availability need be a problem. Plenty of G1s about who are under-employed or semi-retired. Pay us what we're really worth, (well above award!), as experienced Grade 1's with all the training approvals, and there would be dozens who'd re-locate to Toowoomba or Bendigo. But that probably is beyond the horizon of the bean counters on the QF flying school project.
happy days,
