The CircleRoute is a pair of circular Transperth bus routes through Perth's suburbs.
[1][2] It was operated by Swan Transit with Mercedes-Benz O305 buses in a special livery with purple bands blended into the green blocks of the standard colour scheme, with an elliptical shaped logo featuring two arrows in white.
[9] Prior to the CircleRoute's introduction, Perth had limited cross-suburban routes, with most of the network focused on transporting people towards the Perth central business district, and to a lesser extent, regional centres such as Fremantle.
[10] The routes were renumbered from 98 and 99 to 998 and 999 on 31 January 2016, as to signify being a part of Transperth's premium, high-frequency services.
Since 25 November 2007, fares have been determined according to the same Transperth zonal system used by other bus routes and trains in the region; prior to that date, the CircleRoute used its own distinct zones.
