National Route 1 forms part of the main coastal route between Victoria and Queensland. The route features a mix of rural highway, arterial and freeway design standards. The route forms part of what is collectively known as Highway 1. It is Australia's coastal highway joining all mainland's state capitals and coastal towns circumnavigating the entire Australian continent. It is also the longest numbered highway in the world, covering more than 14 500 km.
In New South Wales, National Route 1 was truncated by National Highway 1 between Beresfield and Wahroonga, by Metroad 1 between Wahroonga and Waterfall and by M1 at Tweed Heads West.
The southern section of National Route 1 is formed by 2 separate sections of the Southern Freeway, linked by dual carriageway Mt Ousley Road. At the end of southern segment of the Southern Freeway, National Route continues as Princes Highway. The route from Kiama to Sydney is a mix of divided road and freeway, the majority of the route from Gerringong to the Victorian border is undivided rural highway standard and undivided urban arterial within some towns, with some dual carriageway sections sporadically placed between Bomaderry and tourist areas immediately south of Nowra.
The Princes Highway was formed from a string of roads linking Sydney to the Illawarra, which later was renumbered from National Route 1 to Metroad 1 in the Sydney area during the 1990s.
The Princes Highway section of NR1 formed a coastal route from Yallah, in Wollongong's southern suburbs to Melbourne and into South Australia. The route is a mix of urban arterial road, dual carriageway and also rural highway.
