    Adelaide → Darwin (Stuart Highway)

    Explorer's Way: the full drive guide

    The Explorer's Way follows the route John McDouall Stuart took south to north in 1862, and later the Overland Telegraph Line. It is sealed the whole way, which surprises people — the difficulty is not the road surface, it is the distance between anything.

    Seasonal gate & outback safety

    • Open — go
    • Caution
    • High risk / cut

    Sealed the whole way, so the gate is heat, not water. November to February regularly exceeds 40°C through the centre and a breakdown becomes life-threatening. March and October are workable with an early-start discipline.

    Wildlife warning: do not drive at night

    Do not drive the Stuart Highway after dark. Kangaroos, feral camels and unfenced cattle are on the road from dusk, and triple road trains need a kilometre to stop.

    Live road conditions

    NT Road ReportSA Traffic (DIT)

    It is also the only one of these routes that gets you to Uluru, Kata Tjuta and Kings Canyon without leaving bitumen, via the Lasseter Highway turnoff at Erldunda.

    The genuine hazard is heat and fatigue, not terrain. Summer temperatures through the centre regularly exceed 40°C, and the gap between roadhouses can be 250 km with no shade and no coverage.

    The stops, in driving order

    1. 01

      Adelaide → Port Augusta

      305 km in · 3h 30m

      Critical supply point — Last genuinely cheap fuel heading north. Fill and load water here.

      Port Augusta is where the Stuart Highway properly begins and the last genuinely cheap fuel heading north.

      Tip: The Australian Arid Lands Botanic Garden here is free and is the best short introduction to what you are about to drive through.

    2. 02

      Woomera

      480 km in · 2h

      Rocket range town with an open-air missile park. Much of the surrounding Prohibited Area is off-limits.

      Tip: Do not leave the highway corridor here. The Woomera Prohibited Area is active defence land with legal access restrictions.

    3. 03

      Coober Pedy

      845 km in · 4h

      Critical supply point — Fuel, water and mechanical help. Prices climb sharply north of here.

      Opal town where a large share of the population lives underground in dugouts to escape the heat. Underground church, underground motels, and the Breakaways 30 km north.

      Tip: Never walk backwards or step off marked paths on the opal fields — there are tens of thousands of unfenced, unmarked mine shafts, and people have fallen down them.

    4. 04

      Marla / Kulgera (SA–NT border)

      1080 km in · 2h 30m

      Fuel and roadhouse beds. The NT border sits just north of Kulgera.

      Tip: There is no daylight saving in Queensland or the NT; SA runs 30 minutes behind the NT for part of the year. Check your clock before booking anything.

    5. 05

      Erldunda → Uluru-Kata Tjuta (detour)

      1330 km in · 2h 30m to Erldunda, then 3h west

      Critical supply point — The Uluru turnoff. Fuel at Erldunda rather than Yulara or Kings Canyon.

      The turnoff for Uluru and Kata Tjuta — a 244 km sealed run each way on the Lasseter Highway. Uluru is around 348 m high and the base walk is 10.6 km.

      Tip: Climbing Uluru has been permanently closed since October 2019 at the request of the Anangu traditional owners. Do the base walk instead, and start it at first light in warmer months.

    6. 06

      Alice Springs

      1530 km in · 2h 30m from Erldunda

      Critical supply point — The only full-service town in the centre. Tyres, servicing, supermarket, medical.

      The halfway city: full services, hospital, mechanics, and the base for the West MacDonnell Ranges — Ormiston Gorge and Ellery Creek Big Hole are both on sealed roads.

      Tip: Service the vehicle here. It is the only place between Port Augusta and Katherine with proper workshops and parts.

    7. 07

      Tennant Creek & Karlu Karlu (Devils Marbles)

      2035 km in · 4h

      Critical supply point — Last substantial town before the long run to Katherine.

      Karlu Karlu, 100 km south of Tennant Creek, is a field of granite boulders that is a sacred site and a registered conservation reserve. Best at sunrise or sunset.

      Tip: There is a basic campground at Karlu Karlu. Staying the night is the whole point — the colour change at dawn is the reason to be there.

    8. 08

      Daly Waters & Mataranka

      2625 km in · 4h

      The Daly Waters Pub is the classic outback pub stop. Mataranka's Rainbow Springs thermal pool sits at about 34°C year-round.

      Tip: Thermal pools in the Top End can close for saltwater crocodile management after wet-season flooding. Check the current status on arrival, not before you leave.

    9. 09

      Katherine

      2735 km in · 1h 15m

      Critical supply point — Full services and the last big restock before Darwin.

      Nitmiluk (Katherine Gorge) and the junction with the Savannah Way west to the Kimberley.

      Tip: Canoeing the gorge is dry-season only. Book ahead in peak July.

    10. 10

      Darwin

      3050 km in · 3h 30m

      The northern end. Kakadu and Litchfield are both accessible from here — Litchfield is the easy sealed-road option, Kakadu takes days.

      Tip: Do not swim anywhere around Darwin that is not a designated, managed swimming area. Saltwater crocodiles are present in every waterway including tidal creeks and beaches.

    Drive planning: legs, fuel and conditions

    Three paces, same road: highway pace, a towing or 4WD rig, and what the day actually takes once fatigue and photo stops are in it.

    How we get these: standard is moving time at signposted highway pace. Rig time assumes a 90–100 km/h cruise and slower acceleration — roughly 20% longer. Realistic pace adds a 15-minute fatigue stop every two hours (the national driver-fatigue guidance) plus about ten minutes an hour for photos, fuel and legs. Plan daylight around the realistic column, not the standard one.

    What can go wrong

    • Between Glendambo and Coober Pedy there is a 253 km stretch with no fuel, no water and patchy-to-absent phone coverage. Fill up before it, every time.
    • Do not drive at dawn, dusk or night on the Stuart Highway. Cattle, camels, kangaroos and roos feeding on roadkill make night driving the single most dangerous thing you can do on this route.
    • Carry a minimum of 4 litres of water per person per day plus a reserve. If you break down, stay with the vehicle — it is shade, it is visible from the air, and it is far easier to find than a person walking.
    • Sections of the Stuart Highway have no speed limit signage variation but do have long single-lane overtaking conditions with road trains up to 53.5 m. Allow well over a kilometre of clear road before committing to an overtake.

    Conditions change seasonally and after storms. Check current conditions with the road authority before relying on any of this.

    Common questions

    Yes. Adelaide to Darwin on the Stuart Highway is bitumen end to end, and the Uluru detour via the Lasseter Highway is sealed as well. You only need a 4WD if you add unsealed side trips such as parts of Kakadu or the Mereenie Loop.

    Ten days one way is comfortable if you drive four to six hours a day. Add Uluru, Kata Tjuta and Kings Canyon and you want fourteen. Doing it in under a week means seeing the highway and very little else.

    No. The climb closed permanently on 26 October 2019 at the request of the Anangu traditional owners. The 10.6 km base walk is open, and in the warmer months rangers ask you to start it at first light and be finished before the heat of the day.

    The 253 km between Glendambo and Coober Pedy in South Australia is the one most people get caught by. Roadhouse hours vary, so treat every open bowser as the last one.
