Three hundred and six kilometres. That's the distance between Sandfire Creek and Broome on the Great Northern Highway — red dirt, flat horizon, and not a single bowser in between.
In normal times, that gap demands respect. During Australia's 2026 fuel crisis, it demands a plan.
Whether you're running the Stuart Highway from Adelaide to Darwin, tackling the Gibb River Road in the Kimberley, or threading the Savannah Way across the Gulf Country, outback australia fuel planning has never mattered more. Remote roadhouses operate on small tanks with infrequent deliveries, and the supply chain that feeds them is under strain from the Strait of Hormuz crisis.
This guide covers seven of Australia's longest drives with the fuel stops, distances, and hard-won tips you need to travel them safely right now.
For context on the national fuel situation, see our guide to the 2026 fuel shortage. For the Nullarbor specifically, we've written a dedicated fuel stop guide.
The golden rules of outback fuel planning#
These apply to every route in this guide. Burn them into your brain before you leave the bitumen.
Fill up at every single stop#
No exceptions. Don't bypass a roadhouse hoping the next one is cheaper. It won't be, and it might not be open. A caravaner on the forums learned this after running out of fuel 30km past Wyandra because he skipped Cunnamulla's servo looking for a better price. The tow truck cost more than a year of fuel savings.
Know your real consumption#
Your car's claimed fuel economy is fiction out here. Real-world numbers when loaded and touring:
| Scenario | Typical consumption |
|---|---|
| Sedan, unloaded | 10-12 L/100km |
| SUV/4WD, loaded | 14-17 L/100km |
| Towing mid-size van | 16-19 L/100km |
| Heavy 4WD + large van | 18-22 L/100km |
Use the 75% rule#
Whatever your theoretical tank range, plan on 75% of it. A vehicle doing 16L/100km with a 140-litre tank has a theoretical range of 875km. Plan for 650km. Wind, corrugations, soft sand, and detours eat the rest.
Slow down to go further#
Dropping from 120km/h to 100km/h improves fuel economy by 15 to 20%. Over 500km, that saves roughly 10 litres — about $30 at current outback prices, plus the added range might be the difference between reaching the next servo and calling for help.
Use fuel apps and call ahead#
PetrolSpy and FuelMap show prices and locations. FuelCharge gives access to IOR diesel outlets with 24/7 availability across the outback. Many roadhouses post fuel supply updates on their Facebook pages. Call ahead if you're unsure — a 30-second phone call beats a 3-hour wait for a tow truck.
Carry cash#
EFTPOS fails in remote areas. Some roadhouses are cash-only. Carry at least $200, more if you're heading deep into the outback.
Route 1: Stuart Highway — Adelaide to Darwin (3,000km)#
The Stuart is Australia's spine — the sealed highway running dead straight through the red centre from Adelaide to Darwin. It's well-serviced by outback standards, but the distances between stops demand attention.
Key fuel stops and distances#
| From | To | Distance |
|---|---|---|
| Adelaide | Port Augusta | 310km |
| Port Augusta | Woomera | 175km |
| Woomera | Glendambo | 110km |
| Glendambo | Coober Pedy | 253km |
| Coober Pedy | Marla | 235km |
| Marla | Erldunda | 240km |
| Erldunda | Alice Springs | 200km |
| Alice Springs | Ti Tree | 195km |
| Ti Tree | Barrow Creek | 90km |
| Barrow Creek | Tennant Creek | 135km |
| Tennant Creek | Three Ways | 25km |
| Three Ways | Dunmarra | 245km |
| Dunmarra | Daly Waters | 3km |
| Daly Waters | Larrimah | 95km |
| Larrimah | Mataranka | 75km |
| Mataranka | Katherine | 105km |
| Katherine | Pine Creek | 90km |
| Pine Creek | Adelaide River | 110km |
| Adelaide River | Darwin | 115km |
Longest gap#
Glendambo to Coober Pedy at 253km. Comfortable for most vehicles on a full tank, but if you're towing at 20L/100km, that's 50 litres — more than half a standard 90-litre tank. Fill up at Glendambo without fail.
Current conditions (March 2026)#
Darwin prices have exceeded $2.30 per litre. Alice Springs is the major resupply point for the central section. The Stuart Highway's roadhouses are generally still supplied, but the Territory's remote communities operate on minimal reserves. Don't assume supply is guaranteed at every stop.
Camping along the Stuart#
If you're driving the Stuart to reach campgrounds in the Red Centre or the Top End, check availability before you commit to the drive. Sites around Alice Springs and Kakadu fill up fast during the dry season. Set up a CampWatch alert so you're not driving 3,000km only to find your campground full.
Route 2: Gibb River Road — Derby to Kununurra (660km)#
The Gibb is the Kimberley's iconic unsealed adventure — and one of Australia's most fuel-critical drives. It's open roughly May to October (wet season closes it), and fuel availability is limited at the best of times.
Key fuel stops#
| From | To | Distance |
|---|---|---|
| Derby | Imintji | 220km |
| Imintji | Mt Barnett | 80km |
| Mt Barnett | El Questro | 260km |
| El Questro | Kununurra | 100km |
The gap that matters#
Derby to Imintji (220km) and Mt Barnett to El Questro (260km) are the stretches that catch people out. On corrugated unsealed road, fuel consumption jumps to 20 to 25L/100km for a loaded 4WD. That 260km gap could burn 65 litres.
Carry extra fuel — it's not optional#
The Gibb River Road is one of the few Australian drives where carrying extra fuel isn't just prudent — it's essential. A long-range tank or 40 litres in jerry cans is the minimum recommendation.
The 2023 warning#
In 2023, heavy rainfall raised the Barrett and Durack river crossings, blocking fuel truck deliveries. A Gibb River Road roadhouse actually ran out of fuel. Travellers were stranded until the waters dropped and deliveries resumed. It happened before the current crisis. It could happen more easily now.
Current conditions#
WA's broader fuel shortages have affected the Goldfields, South West, and Great Southern regions. The Kimberley's supply chain runs through these same stressed networks. Check with roadhouses before you set out on the Gibb.
Route 3: Great Northern Highway — Perth to Broome (2,200km)#
A sealed highway running up WA's coast and through the Pilbara mining country. Well-serviced by WA standards, but with one notably long gap.
Key fuel stops#
Perth → Geraldton (420km) → Carnarvon (480km) → Nanutarra (355km) → Newman (turnoff, 450km from Nanutarra via Great Northern) → Port Hedland → Sandfire (310km from Port Hedland) → Broome (306km from Sandfire)
The gap that matters#
Sandfire Creek to Broome at 306km is one of the longest gaps on any major sealed road in Australia. If you're towing at 18L/100km, that's 55 litres of fuel with no backup. Make sure you're full at Sandfire.
Current conditions#
WA mining operations in the Pilbara have reported fuel supply disruptions. The diesel demand from mining is enormous — it competes directly with the road-trip supply. Port Hedland and Newman are mining towns first, travel stops second. Fuel is available but prices reflect the demand.
Route 4: Savannah Way — Cairns to Broome (3,700km)#
Australia's adventure drive across the tropical north, running from the Coral Sea to the Indian Ocean through the Gulf Country. A mix of sealed and unsealed, with some sections requiring 4WD.
Key fuel stops#
Cairns → Undara (280km) → Georgetown (150km) → Normanton (380km from Georgetown via Croydon) → Burketown (230km) → Borroloola (390km) → Mataranka (670km, via Roper Highway) → Katherine (105km) → Kununurra (510km) → Halls Creek (360km) → Fitzroy Crossing (290km) → Broome (395km)
The gaps that matter#
The Gulf Country section between Normanton and Borroloola is the most remote stretch. Distances between reliable fuel stops can exceed 350km on unsealed roads where consumption jumps dramatically. This section requires careful fuel planning and extra carrying capacity.
Self-sufficiency is essential#
The Savannah Way passes through some of the most remote country in Australia. Mobile coverage is near zero through the Gulf. Carry extra fuel, extra water, a satellite communication device, and a recovery kit. Tell someone your itinerary and expected check-in times.
Route 5: The Outback Way — Winton to Perth via Alice Springs (2,800km)#
Marketed as "Australia's longest shortcut," the Outback Way connects Queensland to Western Australia through the dead heart of the continent. Much of it is unsealed. It's not a shortcut by any measure — it's an expedition.
Key fuel stops#
Winton → Boulia (300km) → Tobermorey (Hay River, 375km) → Alice Springs (530km from Boulia via Plenty Highway, with limited stops) → Yulara/Uluru (445km) → Docker River (250km) → Laverton (560km) → Kalgoorlie (360km) → Perth (595km)
Reality check#
Some stretches exceed 350km between fuel stops. On unsealed road with corrugations, expect 20 to 25L/100km in a loaded 4WD. You need a long-range tank and jerry cans — there's no way around it. This route is for experienced outback travellers with properly set-up vehicles.
Route 6: Pacific Highway — Sydney to Brisbane (920km)#
A completely different proposition. The Pacific Highway is a fully sealed, well-serviced motorway with fuel stops every 50 to 100km. You're never more than an hour from a servo.
Current conditions#
The Pacific Highway hasn't experienced the station closures and rationing hitting regional NSW. But prices have risen sharply — expect $2.00 to $2.20 per litre through the Hunter Valley and mid-north coast. Budget an extra $30 to $50 for the trip compared to pre-crisis costs.
Why it's still worth mentioning#
If the fuel situation has you rethinking a remote outback trip, a coastal drive is a solid alternative. The NSW coast has excellent campgrounds within easy reach of fuel, food, and services. Browse NSW south coast campgrounds for ideas, or explore all campgrounds near you.
Route 7: Great Ocean Road — Melbourne to Warrnambool (250km)#
Short, scenic, and usually hassle-free. But Victoria has been one of the hardest-hit states in the fuel crisis. Robinvale, Hattah, Wedderburn, and Bonnie Doon all ran completely dry in March 2026.
Current conditions#
The Great Ocean Road towns themselves (Torquay, Lorne, Apollo Bay, Port Campbell) are larger tourist centres with multiple servos. Supply has been more reliable here than in regional farming communities. But fill up in Melbourne or Geelong before heading out — don't wait for the first coastal town.
Nathan Falvo, who's run his Robinvale servo for 25 years, said it plainly: "I've been here at this business for 25 years and I've never seen this happen before." The crisis is real, even in Victoria's populated south-west.
Carrying extra fuel on long drives#
The basics#
Australian law allows up to 250 litres of fuel in approved containers (AS/NZS 2906) for personal use. A full 20-litre jerry can weighs about 25kg.
Petrol containers: Restricted mounting — not on front/rear of vehicle, not inside the cab, not on the back of a caravan. Ute tray or purpose-built rack only.
Diesel containers: Fewer restrictions. Can be mounted in more positions since diesel isn't classified as explosive in the same way.
Jerry cans vs long-range tanks#
Jerry cans are cheap and accessible, but experienced tourers consistently recommend long-range replacement tanks for regular outback travel. Benefits: lower centre of gravity, no heavy lifting, no fume risk, and no fumbling at the roadside in 40-degree heat.
For a one-off trip, two or three 20-litre jerry cans in proper mounts will do the job. For regular touring, a long-range tank is one of the best modifications you can make.
Safety non-negotiables#
- Fill containers on the ground, never in the vehicle (static ignition risk)
- Leave room for heat expansion — fuel expands in outback temperatures
- Never store fuel containers inside the passenger compartment
- Inspect containers daily for leaks
- Carry a fuel tank repair kit (about $40) for emergencies
FAQ#
What's the longest gap between fuel stops in Australia?#
On sealed highways, the longest common gap is Sandfire Creek to Broome at 306km on the Great Northern Highway. On outback tracks, gaps can exceed 350km (the Outback Way and Canning Stock Route). On the Stuart Highway, the longest gap is Glendambo to Coober Pedy at 253km.
Is AdBlue available at remote roadhouses?#
Inconsistently. If your diesel vehicle requires AdBlue, carry a spare container. Don't assume it'll be available at every stop. Most major stops on the Stuart Highway stock it, but smaller roadhouses on the Gibb River Road and Savannah Way may not.
What's Opal fuel and can my car use it?#
Opal is a low-aromatic unleaded fuel sold at some Aboriginal community servos. It works in any vehicle that runs on regular unleaded. Don't avoid a stop or skip a fill-up because they sell Opal instead of branded fuel.
Should I cancel my outback road trip because of the fuel shortage?#
Not necessarily, but adjust your plans. The major touring routes (Stuart Highway, Great Northern Highway) are still being supplied. The riskier drives (Gibb River Road, Savannah Way, Outback Way) require more preparation than usual. Carry extra fuel, call ahead, and have a backup plan. Regional towns need your tourism dollars — cancelling hurts them as much as the fuel shortage does.
What apps help with outback fuel planning?#
PetrolSpy and FuelMap for prices and locations. FuelCharge for IOR diesel outlet access with 24/7 availability. The NRMA app for NSW-focused stations. Follow individual roadhouse Facebook pages for real-time supply updates.
Plan hard, travel confident#
Australia's outback drives are extraordinary — and they demand respect even in normal times. During the 2026 fuel crisis, the difference between a great road trip and a disaster comes down to planning.
Know your route. Know your consumption. Fill up everywhere. Carry extra if you're heading off the beaten track. And tell someone where you're going.
The red centre, the Kimberley, the Gulf Country, the Top End — they're all still out there. They just need you to show up prepared.
If you're heading to a campground at the end of one of these drives, check availability before you go. And if your campground is booked, set up a CampWatch alert — we'll text you when a spot opens up so you can commit to the drive with confidence.
Seen a campground you want but the dates are gone?
CampWatch monitors popular campgrounds across Australia around the clock and texts you when the dates you want reopen.
