Every time I travel with them, we leave on time, and they really work hard to maintain the schedule. E.g. when there are roadworks on the range, we use the diversion route instead of sitting in the traffic. The $10 minibus special is the cheapets way between Brisbane and Toowoomba apart from hitching, and the normal coach services are great - twice the legroom of Greyhound, plus you are given a bottle of water and a snack. They always have newspapers as well. Furthermore, they don't play the radio or a dumb movie like Greyhound does, so you can study, read, or listen to your own music in peace.
