Gunbarrel Highway Road Trip: Route, Permits, Fuel and 4WD tips
The Gunbarrel Highway
There's something about a road that disappears into the desert that captures the imagination. No traffic lights, no crowds, just vast open country, red dirt and the freedom to explore.
But don't let the name fool you. The Gunbarrel Highway is no ordinary highway.
Stretching approximately 830km between Wiluna and Warburton in Western Australia, this legendary desert route dishes up relentless corrugations, rocky sections, washaways and some of the most isolated country in Australia.
It's a journey that rewards experience, preparation and a healthy respect for the outback.
And for those travelling with a caravan or camper trailer, there's one very important question to answer before setting off: is your setup really up to the challenge?
A well-secured awning makes camp more comfortable when the weather turns. Tiegear’s practical setup gear, including guy ropes, soft springs and handy storage, helps make pitching and packing up simpler. Find Tiegear awning and caravan essentials at the Caravan World shop.
Is the Gunbarrel Highway suitable for caravans?
Let's get straight to it. The Gunbarrel Highway is not a road for conventional caravans or inexperienced off-road travellers.
Even for seasoned tourers, towing adds another level of complexity. Severe corrugations can punish suspension, tyres, chassis and fittings, while washaways and rough sections demand careful vehicle placement.
A purpose-built, heavy-duty off-road camper trailer may be an option for experienced travellers, depending on conditions and the manufacturer's recommendations. However, even an off-road caravan should not be assumed suitable simply because it carries an off-road badge.
For many caravanners, the more sensible option is to leave the van securely stored and tackle the Gunbarrel as a dedicated 4WD adventure.
This is remote touring at its most demanding, where vehicle capability, recovery knowledge and self-sufficiency matter far more than creature comforts.
A road built for adventure
The Gunbarrel Highway is closely associated with legendary Australian surveyor Len Beadell and his Gunbarrel Road Construction Party.
During the 1950s, Beadell and his crew forged a network of roads through remote desert country to support Australia's weapons testing and defence programs.
Beadell famously preferred roads as straight as a gun barrel, and the name stuck.
Today, the Gunbarrel is part of an extraordinary network of outback tracks, including the Gary Highway, Connie Sue Highway and Anne Beadell Highway.
Of course, these weren't unexplored lands. Aboriginal peoples had travelled, lived and maintained connections across these deserts for tens of thousands of years before the construction of the roads.
The modern Gunbarrel follows a landscape rich in First Nations history, later European exploration and Australia's more recent surveying heritage.
It's this combination of history and remote adventure that makes the journey so memorable.
Create a more comfortable space outside your van with Cgear mats and privacy screens. The Multimat helps keep a cleaner area underfoot at camp, while the screen range adds shade and privacy beside your awning. Explore Cgear camping mats and caravan accessories at the Caravan World shop.
Planning your Gunbarrel Highway road trip
The most commonly travelled route runs between Wiluna and Warburton, via Carnegie Station, Everard Junction and the Heather Highway.
Allow at least six to ten days for the journey, depending on road conditions, permitted transit times, vehicle capability and how often you stop.
This isn't a route to rush. Some sections can be painfully slow, and unexpected delays are always possible.

The journey: Wiluna to Warburton
Stop 1: Wiluna - the gateway to the Gunbarrel
Your adventure begins in Wiluna, the gateway to two of Australia's most iconic outback routes: the Canning Stock Route and the Gunbarrel Highway.
This is the place to get organised.
Fill your fuel tanks, stock up on supplies, check your communications equipment and confirm the latest road conditions.
Once you leave town, services become few and far between.
Before departure, contact the Shire of Wiluna for current road information. Don't assume conditions will be the same as they were for travellers who crossed a week earlier.
Stop 2: Carnegie Station - your last major resupply point
Approximately 340km east of Wiluna, Carnegie Station provides a welcome break before the toughest part of the adventure.
Historically, the station has offered basic camping, accommodation, fuel and limited supplies, although availability should always be confirmed directly before travelling.
For those carrying a suitable off-road camper trailer, this can be a chance to enjoy a proper rest, check the vehicle and trailer, and prepare for the more challenging country ahead.
The next stretch towards Warburton is where the Gunbarrel really earns its reputation.
Make sure you have enough fuel to complete the journey without relying on an unconfirmed supply.
Stop 3: Mangkili Claypan and Geraldton Bore
East of Carnegie Station, the track narrows and the country becomes increasingly remote.
Expect rough corrugations, stony sections and occasional boggy ground, particularly after rain.
Mangkili Claypan provides an interesting landmark near the David Carnegie Road junction. Take care around claypans, which can become impassable when wet.
Further along, Geraldton Bore is a well-known stopping point, recognisable by the trees surrounding it.
While historic bores and wells are marked along the Gunbarrel, never rely on them for drinking water. Carry sufficient water for the entire journey, including a substantial emergency reserve.
Stop 4: Everard Junction and Camp Beadell
At Everard Junction, the Gary Highway heads north, another reminder of the remarkable network of desert roads constructed by Beadell's team.
Continuing east, Camp Beadell and nearby Mount Beadell are among the historical highlights of the journey.
At Mount Beadell, a memorial and replica theodolite commemorate the surveyor whose work helped shape modern outback travel.
It's worth taking time here to appreciate not only the history but also the vastness of the country surrounding you.
This is the sort of place where the silence, space and isolation become part of the adventure.
Stop 5: Warburton - back to civilisation
From the Gunbarrel, the Heather Highway connects travellers with the Great Central Road and the final run into Warburton.
After days of dust, rough tracks and remote camping, reaching Warburton can feel like a luxury.
Warburton Roadhouse offers fuel, basic supplies and accommodation options, subject to availability.
It's a welcome opportunity to refuel, restock and reassess the next leg of your outback journey.
Travellers continuing east towards Yulara and Uluru will need to organise the appropriate Northern Territory transit permits before departure.
Permits and access: what you need to know
The Gunbarrel Highway crosses and connects with roads through Aboriginal lands, and permits are an essential part of trip planning.
The original Gunbarrel alignment is not completely accessible to the public.
In particular, the abandoned section between Warburton and Warakurna is not open to general public travel. Other sections may also have restrictions, so your route must be confirmed before departure.
Depending on your itinerary, permits may be required through:
Central Land Council if continuing into the Northern Territory
Permits can have strict transit limits, so plan your overnight stops and total travel time accordingly.
Respect community access restrictions, culturally significant places and camping conditions throughout the journey.
What to pack for the Gunbarrel Highway
Remote desert travel requires a different approach to packing, particularly if you're accustomed to caravan parks, powered sites and regular roadhouses.
Your preparation should cover:
Fuel: Calculate consumption for corrugations, low-speed driving and any towing load, allowing a generous reserve.
Water: Carry enough drinking, cooking and washing water for the entire journey, plus emergency supplies.
Communications: A satellite phone or satellite messenger, registered personal locator beacon and UHF radio.
Vehicle recovery: Suitable recovery equipment, tyre repair gear, compressor and essential spare parts.
Navigation: Reliable offline mapping, printed maps and a backup navigation plan.
Food and camping: Be completely self-sufficient and carry extra provisions for unexpected delays.
Hema's Great Desert Tracks Atlas & Guide and Great Desert Tracks Map are useful additions to your desert touring kit.
And don't forget the little things. Check your spare wheel, secure everything that can shake loose and inspect your vehicle regularly.
Hundreds of kilometres of corrugations have a way of finding every weak point in a touring setup.
When is the best time to drive the Gunbarrel Highway?
May to September generally offers the most favourable conditions for desert travel, with cooler days and less extreme temperatures.
Summer temperatures can climb well into the 40s, making breakdowns and delays potentially dangerous.
Rain can also transform sections of the track, particularly around claypans and low-lying areas.
Even during the cooler touring months, conditions can change quickly. Check weather forecasts and road reports immediately before leaving and remain prepared to change your plans.
Is the Gunbarrel Highway worth the adventure?
Absolutely - for the right traveller.
The Gunbarrel isn't about ticking off attractions or reaching the next powered site before happy hour.
It's about the challenge of the journey, the history beneath your wheels and experiencing a part of Australia that relatively few travellers get to see.
For experienced 4WD tourers, it's one of Australia's great outback adventures.
For caravanners planning a bigger lap, it could be the perfect reason to park the van for a few days and head into the desert.
Just remember: the Gunbarrel Highway demands respect. Do your homework, prepare properly and never underestimate the country you're travelling through.
Because out here, the journey really is the destination.
