So after the 747 load of tourists exit the terminal, where do they go? Oh that's right, they wait for the line of buses to take them on the long trip to anywhere else. Or how about the FIFO guy who has to drive to/from TWB or catch the bus before/after catching his flight. Are they hoping they'll all live in Toowoomba instead? Can't see it working. Avalon is different. It's between Geelong and Melbourne, freeway & reasonable public transport in either direction, and is effectively suburban. And still only Jetstar go there. Sure this may capture some FIFO traffic, but Toowoomba is not a realistic alternative to Brisbane. Otherwise everyone would just be using the Gold or Sunny Coast airports now.
