Sydney Buses
Sydney Buses travel through the city and beyond almost 24 hours a day. Most of the bus routes within the City of Sydney are prepaid only to reduce delays, so you'll need to buy a ticket before you get on board. There are ticket outlets all over the city and you can usually find one near bus stops.
The main bus stops in the city centre are at Circular Quay, Wynyard and Central Stations, and the Queen Victoria Building (QVB) where you will also find visitor information kiosks.
