CountryLink was a passenger rail and road service brand that operated in regional areas of New South Wales, and to and from Canberra, Brisbane and Melbourne. Originally created as a business unit of the State Rail Authority of New South Wales, it later became a subsidiary of RailCorp. CountryLink operated rail services using XPT and Xplorer rolling stock, with connecting coach services operated under contract by private operators.

The State Rail Authority, a former statutory authority of the Government of New South Wales, operated and maintained railways in the Australian state of New South Wales from July 1980 until December 2003.
