The Public Transport Authority of the Government of Western Australia tenders the provision of bus routes in Perth to private operators;[1] privatisation of Transperth services began in 1993 and was completed in July 1998.
[citation needed] CAT routes are zero fare, circular services which operate in the central business districts of Perth and major regional centre Joondalup.
Numbered 998 clockwise and 999 anticlockwise, it connects major hospitals, universities, schools, shopping centres, and all urban rail lines.
High frequency bus services operate at minimum every 15 minutes between 7am and 7pm on weekdays, 8am and 7pm on Saturdays, and 9am and 7pm on Sundays.
[citation needed] (Vale Shopping Centre) Transperth operates bus routes servicing special events such as sport matches and concerts.

When only part of a train line is closed, the replacement buses will operate between the nearest open stations.
