The South East Busway is a grade separated bus-only road running south from the Brisbane central business district to Eight Mile Plains in Queensland, Australia. The busway was completed to Woolloongabba in September 2000 and to Eight Mile Plains in April 2001. An extension of the busway to School Road at Rochedale was completed in 2014 with no additional busway stations. The maximum capacity of the busway is 18,000 commuters an hour during peak periods. The busway carries an estimated 70 million passengers annually.

Bus rapid transit (BRT), also referred to as a busway or transitway, is a bus-based public transport system designed to have much more capacity, reliability and other quality features than a conventional bus system. Typically, a BRT system includes roadways that are dedicated to buses, and gives priority to buses at intersections where buses may interact with other traffic; alongside design features to reduce delays caused by passengers boarding or leaving buses, or paying fares. BRT aims to combine the capacity and speed of a light rail transit (LRT) or mass rapid transit (MRT) system with the flexibility, lower cost and simplicity of a bus system.
