I would have thought Rex or Qantaslink would have been interested, if not exactly keen.
Rex and Qlink are well enough established that they don't need to take any risks - they sit on the fat, profitable routes and would increase services out of Armidale or Tamworth or Port Macquarie in preference to starting something new and copping a loss.
JetGo, FlyDuck and FlyCorp are all taking experienced charter teams and applying them to new opportunities, mostly routes previously proven by Brindabella. When/if they get established they may be in a position to take on the big boys but with limited slots into the Sydney the Govt continues to deny regional people access to reasonable services and denies innovative and efficient providers the opportunity to consolidate and grow.
I wonder how much Rex Group/Q group/VA donates to the LibNats compared to FlyDuck and JetGo?
