In New South Wales, Highway 1 is a 1,351-kilometre (839 mi) long route that crosses the state, from the Queensland/New South Wales border near Tweed Heads to the Victorian border near Timbillica. It provides the main coastal route between Brisbane and Melbourne via Sydney. Highway 1 continues around the rest of Australia, joining all mainland state capitals, and connecting major centres in Tasmania.
Highway 1 is often associated with summer road excursions for people of New South Wales since the whole route passes very near to the ocean. Parts of the route are also busy intercity or commuter routes.
