Since I wrote this post about the buses between Brisbane and Toowoomba the situation has changed. MaxExpress seems to have gone out of business. Suncoast Pacific has changed it’s times to just 11pm and 4pm, from Brisbane to Toowoomba and 8pm and 2pm back. The cost of these is $18 for an adult and $16 for a concession.
Just now researching this, I have noticed that there is a company called MightyBus that is to start services on the 3rd July, and it looks like they will be $7.95. My guess is this will force Greyhound (Suncoast) to drop their prices.
