I dont think those options will happen.
The only ones that might would be MEL LH or Jetstar.
There are a lot of current QF LH crew on the transfer list to BNE & SYD there would be a riot if they let AO crew take slots before the current LH crew! I seriously doubt the FAAA would let them jump the transfer list into those bases (unless they were casual crew - which is allowed in the LH EBA) and the company would be pi##ing a lot of crew off if AO crew were allowed to 'push in line' for the BNE & SYD bases.
The other fact is there is no transfer agreement for any subsidiary's crew directly into QF Longhaul within the EBA (not that EBA's seem to mean that much any more).
Good luck with it though
