Highway 1 between Sydney and Melbourne is actually the longer route in comparison with the inland Hume Highway but it certainly has the advantage of being the more scenic coastal way through interesting seaside villages and — if one wanted to go for a swim — a great number of unspoiled beaches. Highway 1 from Sydney to Melbourne is named Princes Highway in honor of England's then Prince of Wales who visited Australia in 1920. The Prince of Wales was later crowned King Edward VIII but gave up the throne to marry an American divorcee. Princes Highway continues beyond Melbourne to Port Augusta in South Australia.More »
Highway 1 between Melbourne and Adelaide is one of the shorter Highway 1 sections between Australia's capital cities but is by no means the shortest route from Melbourne to Adelaide. As with the New South Wales Princes and Hume Highways, the shorter route is inland rather than coastal, but the longer coastal way is certainly more scenic. Leaving Melbourne, the city named after England's William Lamb, the 2nd Viscount Melbourne, Highway 1 heads west to Geelong and then along the Victoria and South Australia coast before cutting inland to the Lower Murray and into Adelaide.More »
From Adelaide, Highway 1 continues as the Princes Highway northwest to Port Augusta and then westward away from the coast on the Eyre Highway until Ceduna when it again hugs the coast at the southern end of the Nullarbor until the Western Australia border. The Eyre Highway continues west until Norseman, then turns south to Esperance. From Esperance it continues west and southwest as the South Coast Highway before heading north on the South Western Highway to Bunbury where it then follows the Old Coast Rd to Fremantle and then on to Perth.More »
Highway 1 is the Brand Highway heading north from Perth to Geraldton when it becomes the North West Coastal Highway bypassing the World Heritage Ningaloo Coast, one of the world's now more than 900 World Heritage sites, and through the Pilbara region to Karratha and on to Port Hedland where the Great Northern Highway takes up the Highway 1 route through the Kimberley past Purnululu National Park and on to Kununurra where Highway 1 has now become the Victoria Highway into the Northern Territory. It then heads north at the junction of the Stuart Highway and into Darwin, the city named after evolutionist Charles Darwin who sailed on the HMS Beagle in the early 1800s. Darwin was not on the Beagle when the ship sailed into Darwin Harbour in 1839.More »
From Darwin double back on the Sturt Highway, heading south past the Victoria Highway junction, then turning east into Carpentaria Highway to Borroloola. You then follow the Savannah Way east through Burketown, Normanton and Georgetown in Queensland all the way, if you prefer, to Cairns, popular jump-off point to the Great Barrier Reef, or you can cut across to Innisfail and head south on the Bruce Highway through Townsville, Mackay, Rockhampton, the Sunshine Coast and on to Brisbane.More »
•Brisbane to Sydney
The Brisbane-to-Sydney leg of Highway 1 is the Pacific Highway which runs mostly along the New South Wales coast after Tweed Heads on the Queensland-NSW border. Southward the highway takes in the western edge of Byron Bay, Ballina, Coffs Harbour, Port Macquarie, Newcastle and thence to Sydney on the Newcastle Freeway. From Cairns in Queensland to the eastern Victoria coast, Highway 1 generally follows the coast of the Pacific Ocean. All in all, the circumferential Highway 1 is some 14,500 kilometres or 9000 miles from Sydney to Sydney around the continent. It is said to be the longest national highway in the world.
