State Transit Authority of New South Wales - Sydney Buses

Sydney Buses is a commuter bus service operating in Sydney. The network—comprising buses in the series 100, 200, 300, 400 and 500—is loosely based on the reach of the city's now-defunct tram network (see Trams in Sydney).

Sydney Buses has grown significantly through acquisitions of smaller bus companies as reforms to contracting arrangements encourage consolidation in the industry. This growth has meant that the fleet size has increased without a corresponding drop in the fleet's average age.

Sydney Buses operates a number of high-profile services:

• Metrobus: The Metrobus services are high-frequency accessible buses. There are currently thirteen Metrobus routes, eight of which are operated by Sydney Buses (M10, M20, M30, M40, M41, M50, M52, M54).
• L90: The L90 service is the longest bus route operated by Sydney Buses.
• 333: Bondi Beach Prepay Only service, the city's first prepay only limited stops bus service.
