The Outback Highway Development Council is a non-profit alliance of local governments formed in 1998 to lobby for the sealing and upgrading of the Outback Highway (OH). It has proposed that the OH be developed to provide an inland route between southern Western Australia and northern Queensland as an alternative to the National Highway 1 along either coast.
Sections of the Outback Highway
The existing roads that make up the highway are:
Great Central Road, a 1,056-kilometre-long (656mi) mostly graded gravel road, with short sealed sections, between Laverton and the junction with Kata Tjuta Road near Yulara. Parts of this road around Warakurna are concurrent with the Gunbarrel Highway
Kata Tjuta Road and Uluru Road in Uluru-Kata Tjuta National Park stretching for 48 kilometres (30mi) between Great Central Road and Lasseter Highway. The OH route passes through the park entry gate where Uluru Road divides into a lane to enter (westbound on the OH), controlled by a barrier and Park Pass payment office, and a separate exit lane (eastbound on the OH) with no barrier or stop sign. OH travellers should check with the National Parks office if a pass is required in either direction.
Lasseter Highway, a sealed 244-kilometre-long (152mi) road between Yulara and Erldunda on the Stuart Highway
Stuart Highway, the section between Erldunda and the Plenty Highway junction (268 kilometres or 167 miles), of the sealed road forming the major north-south route through Central Australia.
Plenty Highway, a mostly unsealed highway between the Stuart Highway and Donohue Highway (498 kilometres or 309 miles).
Donohue Highway, a mostly unsealed highway between the Plenty Highway and the Diamantina Developmental Road just north of Boulia (249 kilometres or 155 miles).
Diamantina Developmental Road (also known as the Boulia-Mt Isa Highway) between the Donohue Highway junction and Boulia (7 kilometres or 4.3 miles).
Kennedy Development Road, a sealed highway, section from Boulia to Winton (362 kilometres or 225 miles).
The Outback Highway project is in effect a series of coordinated but separately-funded projects of Western Australia, Northern Territory and Queensland. The largest is the Western Australian project between Laverton and the Northern Territory border with road sealing due to be completed in 2032 at a cost of A$678million.
Mobile phone coverage is limited and is non-existent for long sections of the highway. A reliable 4G service is only found in major hubs and near some roadhouses and Aboriginal communities.
As of May2026[update], there are a total of 1,161 kilometres (721mi) of the Outback Highway left to seal.
As of May 2026, the following permits are required to travel the Great Central Road:
Great Central Road Laverton to Tjukayirla Roadhouse: apply to WA Dept Planning Lands & Heritage. The application is referred to the Yilka Talintji Aboriginal Corporation.
Great Central Road Tjukayirla Roadhouse to NT Border
Tjukururu Road (the Great Central Road in the Northern Territory between the NT Border and Kata Tjuta Road)
When keeping to the highway itself, permits are not required for travel on other sections of the Outback Highway. Queensland no longer requires permits for the sections in that state.
Further information including fuel availability, tourist information and links for road condition updates are available.
