The first road in Australia designated a "freeway" was the Kwinana Freeway in Perth, western Australia. The first stage of the Kwinana Freeway was begun in 1957.
Australia's first highway was Highway 1, which, although not the world's longest highway, is the world's longest circuithighway. It extends almost entirely around Australia and links all the state capitals (except for Canberra, the National Capital).
