Looks like the Queensland Taxpayer subsidies may have to be handed back to the Queensland Government if Bain aren't willing to go through the trouble of using their mentioned back-up plans (the 700s) for CNS-HND.
CNS-HND is one of the Aviation Investment Fund (AAIF) subsidised routes funded by the Queensland taxpayers, along with QF's BNE-HND which is also taxpayer funded.
