Harris Park Transport[1] was an Australian bus company operating services in the Hills District and Southern suburbs of Sydney.

[2] By the late 1990s, all had been consolidated under the Harris Park Transport and AJ Moore brands.

In 1945, in partnership with GR Sinclair, Moore purchased route 82 Epping to Carlingford.

[4] In December 1981, Red Arrow route 590 commenced between Blacktown and Macquarie Centre as a joint operation between Westbus and Harris Park's Carlingford Bus Service subsidiary.

The Carlingford Bus Service brand didn't last long and was replaced by the Harris Park Transport name.

[9][20][21] Following further negotiations after ComfortDelGro Cabcharge's purchase of Hillsbus, routes 620, 625, 626, 627 and 630 were transferred back to Hillsbus as part of Sydney Bus Region 4 on 25 September 2005, with the remainder staying with Sydney Buses as part of Region 7.

[13][23][9] Harris Park Transport remained as a charter operator under the name CharterBus Direct.

The former Sutherland Bus Service depot in Gymea Bay was retained to store out of use buses.
