Buses in Perth, Western Australia, are operated under the brand Transperth. The Public Transport Authority of the Government of Western Australia tenders the provision of bus routes in Perth to private operators; privatisation of Transperth services began in 1993 and was completed in July 1998. Path Transit, Swan Transit and Transdev WA currently operate services.

Bus operations , all routes operated under Transperth are serviced by accessible buses. Typical Perth bus routes operate every 10–20 minutes in peak times, and every 30–60 minutes off peak on weekdays. Services generally finish before midnight, though many routes finish earlier, between 6:00 pm and 11:00 pm. Weekend services are approximately half weekday levels. Major routes are more frequent, operating every 10–15 minutes off peak on weekdays, and every 15–30 minutes on weekends and evenings.

Most bus routes terminate in Perth, at Elizabeth Quay, Perth Busport, in East Perth, and at suburban bus stations or railway stations. Some services in older areas terminate by looping on suburban streets.

Zero fare routes

CAT routes are zero fare, circular services which operate in the central business districts of Perth, major regional centre Joondalup, and on a route (Surf CAT) linking Stirling and Scarborough. They operate every 5–15 minutes on weekdays, and every 15 minutes on weekends except for Joondalup CAT routes. Similar circular services also operate in the Midland and Rockingham central business districts, although the Rockingham service charges a fare.

CircleRoute

The CircleRoute is a circular service which operates in inner suburbs of Perth. Numbered 998 clockwise and 999 anticlockwise, it connects major hospitals, universities, schools, shopping centres, and all urban rail lines.
