And a quick look at the airline web sites reveal:
ADL-DPS Virgin 2 p/w & JetStar nothing direct.
PER-DPS Virgin 4 p/w & JetStar 3 p/w.
BNE-DPS Virgin 5 direct p/w. I say direct because the new Jet* service from BNE is daily via DRW - why would anyone want to endure a 3 hour wait?
Virgin from BNE 6 hours 15 minutes & JetStar 9hours 20 minutes.
Assume the NT Government is paying heaps of incentives as surely no one from Brisbane is going to fly JetStar?
