Turbo-Props before 6 am
I also seem to recollect the Minister (not sure whether it was the current one or the last one) saying that the airlines would not be allowed to circumvent the curfew by replacing jets with turbo-props!
It was about the time Qantas was talking about the Q400 service direct to Gladstone from Sydney. (I've just checked the schedules to see when they depart and they are not listed - I guess people would rather travel on a jet!)
