It surpasses other famous routes in length, such as the Trans-Siberian Highway (over 11,000 km) and the Trans-Canada Highway (about 8,030 km).
Its most remarkable feature is its circular nature. It forms a giant ring that connects all the state capitals of the country: Sydney, Melbourne, Brisbane, Perth, Adelaide, and Darwin, with a branch to Hobart in Tasmania.
This journey is so emblematic that it has earned the nickname “The Big Lap.” Officially created in 1955, Highway 1 was compiled from an existing network of roads and serves over a million people daily, being a vital artery for commerce and transportation in Australia.
A State-By-State Tour Along The Longest National Highway In The World

Highway 1 does not have a single name. It is a designation applied to a network of roads that change names as it crosses Australian states.
New South Wales (NSW): Incorporates the Pacific Highway and the Princes Highway, passing through Sydney.
Victoria (VIC): The Princes Highway is the main artery, passing through Melbourne.
South Australia (SA): It consists of the Eyre Highway, which crosses the vast Nullarbor Plain.
Western Australia (WA): Uses various roads, such as the Brand Highway and the North West Coastal Highway, passing through Perth.
Northern Territory (NT): The Stuart Highway is the backbone, connecting the region to Darwin.
Queensland (QLD): The Bruce Highway is the main component, passing through Brisbane and Cairns.
Signage also varies, using markers such as M1, A1, or B1. This requires travelers to use detailed maps and understand that they will follow different route designations.
The Main Highlights Along Highway 1
Highway 1 is considered the “ultimate Australian adventure” due to its diversity. It provides access to an incredible variety of landscapes, cultures, and experiences.
The route connects vibrant Australian cities, such as Sydney and Melbourne. It offers access to coastal wonders, from the Gold Coast to the Great Ocean Road (on a popular detour) and Ningaloo Reef.
Moreover, it penetrates the heart of the country, crossing Outback deserts like the Nullarbor Plain, and ancient rainforests, such as the Daintree Rainforest.
The journey is also a unique opportunity for encounters with Australian wildlife, such as kangaroos, koalas, and a vast array of birdlife.
How To Plan Your Journey On The Longest National Highway In The World
Travel and adventure experts agree that planning the “Big Lap” along Highway 1 requires care. Australia has extreme climatic conditions, and the timing of the trip is crucial.
The general rule is to head north during the Australian winter (May to October) and south during the summer (September to April).
For an immersive experience, experts suggest a minimum of three months. The choice of vehicle is also fundamental.
A robust 4×4 is ideal for those looking to explore detours in the Outback. SUVs with a rooftop tent are a more accessible option.
Campervans and car-and-caravan combinations are popular for those seeking more comfort. It is important to match the vehicle to the type of terrain you intend to explore.
Another point of attention is safety. Avoid driving at dawn and dusk to reduce the risk of collisions with animals.
Plan regular stops to combat driver fatigue, a real risk on long and monotonous stretches.
In remote areas, such as the Nullarbor Plain, it’s essential to plan refueling, water, and supplies, although service stations (roadhouses) are available every few hundred kilometers.
A Titan Of Road Trips
Australia’s Highway 1 stands out in the landscape of great global routes. Although the Pan-American Highway is longer in absolute terms (30,000 km), it is an international route interrupted by the Darién Gap.
The distinction of Highway 1 is being the longest national highway in the world that functions as a continuous, circular network within a single country.
This uniqueness makes it a unique and enticing challenge for road travelers from all over the world, solidifying its status as a true titan among legendary roads.
