Pacific Highway is a 790-kilometre-long (491 mi) national highway and major transport route along the central east coast of Australia, with the majority of it being part of Australia's Highway 1. The highway and its adjoining Pacific Motorway between Brisbane and Brunswick Heads and Pacific Motorway between Sydney and Newcastle links the state capitals of Sydney in New South Wales with Brisbane in Queensland, approximately paralleling the Tasman Sea and the Coral Sea of the South Pacific Ocean coast, via regional cities and towns like Gosford, Newcastle, Taree, Port Macquarie, Kempsey, Coffs Harbour, Grafton, Ballina, Byron Bay, Tweed Heads and the Gold Coast, which is part of Queensland. Additionally, between Brunswick Heads and Port Macquarie, the road is also signed as Pacific Motorway, but has not been legally gazetted as such.
