QF discounted fares ?
these would have to be higher than Brindabella were selling or why bother.
QF are in enough trouble without wasting more funds.
Small operators with much lower costs would probably be the only ones who could do some of the very thin Brindabella routes or could Rex do some at a profit ?
With mining contracts disappearing could Corporate Air (Saab 340's etc.) or even Alliance with some of their F50 be interested ?
