Update 24/06/2006: I have written a more up to date recap of this information, it’s here.
Rod and I have been ferrying ourselves between Brisbane and Toowoomba on a fairly regular basis and with the introduction of some cheap bus fairs, it has generally been without the need for cars. (Mine is parked in the Garage with one wheel off). Because there is no decent place on the net to find this information, I’m going to post it here.
There are 3 services, McCafferties/Greyhound, MaxExpress and Suncoast. The McCafferties buses leave on the hour every hour. They are expensive, about $23 for students one way.
MaxExpress runs at 11am, 2pm and 4pm from Brisbane and 8am, 11am, and 2pm from Toowoomba. The cost for these is $18 and $15 for concessions, it is a direct service and takes about an hour and a half.
Update: I’ve spelt a few things wrong, apologies goto McCafferty’s.
