Darwinbus

As of December 2013, the Buslink fleet consisted of 164 buses based out of depots in Berrimah and Humpty Doo, and the then Darwin Bus Service fleet based in Stuart Park consisted of 36 buses.

After assuming control of the former Darwin Bus Service depot and its fleet at Stuart Park in 2014, Territory Transit began replacement of many older buses in the fleet. A total of 17 Mercedes-Benz OC500LE rigid buses with Custom Coaches bodywork were added between 2015 and 2020, with the size of the fleet reducing slightly to 34 buses. While these additions largely displaced older rigid buses produced by MAN and Volvo, three of four Scania L94UA articulated buses were ultimately replaced. A further two buses (which included the last articulated bus) were withdrawn without replacement prior to CDC Northern Territory taking control of the Stuart Park Depot in 2022. A pair of Mercedes-Benz OH1830LE buses, which had previously been used by Buslink-Vivo, were also based at Stuart Park depot but were mostly utilised for charter work.

CDC Northern Territory's depots at Berrimah and Humpty Doo had a combined total of 158 buses as of February 2022, although the vast majority of these buses are not utilised for public bus services, instead performing charter, school bus and special needs transport duties. While a total of 47 buses are painted in the Darwinbus livery of black, white and ochre, 6 of those buses were utilised exclusively as school buses. Since commencement of the new contract, some of these buses have been returned to urban service at the Stuart Park depot.

As of December 2022, CDC Northern Territory operates 192 buses in the Greater Darwin area, and an additional 16 in Alice Springs. The increase in Darwin is largely attributable to inheriting the former Territory Transit fleet at Stuart Park, with the combined urban fleets totalling 79 buses. All Darwinbus services are now exclusively operated by Mercedes-Benz OC500LE buses with a mix of Volgren and Custom Coaches bodywork.
