ComfortDelGro Australia (CDC) is a major Australian operator of commuter buses. It is the second-largest commuter bus operator in New South Wales, and the third-largest commuter bus operator in Victoria. The company was founded in October 2005 as ComfortDelGro Cabcharge, a joint venture between ComfortDelGro (51%) and Cabcharge (49%). In February 2017, ComfortDelGro purchased Cabcharge's stake.

CDC operates services as part of the New South Wales metropolitan bus system under the Hillsbus, Hunter Valley Buses and Blue Mountains Transit brands. In regional New South Wales (Queanbeyan and Yass), CDC operates under the Qcity Transit and Transborder Express brands. In Victoria, CDC operates CDC Ballarat, CDC Geelong and CDC Melbourne.

CDC also has operations outside of Australia. In the United Kingdom, CDC owns and operates as CityFleet which operates coach services in London under the Westbus banner and taxi services in a number of cities.

The joint venture was established in October 2005 to purchase loss-making Westbus (Australia & UK), Hillsbus and Hunter Valley Buses from National Express and the Bosnjak family. The company traces its origins to 1955, when the Bosnjak family established a bus company in Edensor Park.

In 1986, Westbus commenced operating in England with the purchase of ADP Travel Services, Hounslow and Swinards Coaches, Ashford. This was later acquired by Armchair Passenger Transport who were in turn purchased in 2004 by ComfortDelGro.
