Adelaide to Kalgoorlie campervan route across the Nullarbor

The direct run is about 2,170 km via Port Augusta, Ceduna, the Eyre Highway, Norseman and then north to Kalgoorlie. You can belt it out in 4 long days if you enjoy arriving tired and smelling like the inside of a hot fridge. For a hired campervan, 6 to 8 days is the much better rhythm.

A sensible day is 250–450 km out here. That leaves time to refuel before the roadhouse shuts, get a legal camp, and not be driving at dusk when kangaroos, wombats and the occasional confused cow start auditioning for your insurance claim.

• Fast but tiring: 4–5 days, mostly driving.
• Good self-drive pace: 6–8 days, with proper overnight stops.
• With Eyre Peninsula detours: 9–12 days, especially if you swing south to Streaky Bay or Coffin Bay.

Do book the vehicle for the time you actually need. Adding one extra night is usually cheaper than rushing a 3-tonne home-on-wheels into a headwind across the Nullarbor.

The good news: this route is sealed and has regular roadhouses. The catch: roadhouse fuel can sit 30–80 cents per litre above city prices, opening hours vary, and you do not want to roll in with 12 km of range and a heroic attitude.

The longest normal fuel gaps are not insane, but they are long enough to respect. Plan to carry at least a 300 km reserve after each fill, especially in hot weather or a westerly headwind.

• Ceduna to Penong: about 74 km.
• Penong to Nundroo: about 80 km.
• Nundroo to Nullarbor Roadhouse: about 144 km.
• Nullarbor Roadhouse to Border Village: about 184 km.
• Caiguna to Balladonia: about 181 km, on the 90 Mile Straight.
• Balladonia to Norseman: about 191 km.

Dump points and easier potable water are best planned in the bigger stops: Port Augusta, Ceduna, Norseman and Kalgoorlie. Do not assume every roadhouse tap is potable or free for tank filling; ask first, and top up drinking water whenever you can.

Your first couple of nights are the ones to keep simple. Port Augusta is a handy reset after leaving Adelaide: fuel, supermarkets, LPG, dump point options and powered sites if you want to test every switch in the van before the country gets emptier.

After that, think in practical stages: Ceduna for a final big shop, Nullarbor or Eucla for the middle crossing, then Norseman before the run up to Kalgoorlie. Free and low-cost camps exist, but they are not a licence to camp wherever a tyre track meets a sunset.

• Do: use signed rest areas, council-approved RV stops, roadhouse caravan areas and bookable national park campgrounds.
• Do not: empty grey water near camps, run a generator beside someone’s pillow, or camp on lookouts where signs say no camping.
• Check: local fire bans from October to April; rules change quickly in heat and wind.

National park and conservation areas along the way may require online bookings or entry fees, and some camps are not suitable for large motorhomes. If your van is over 7 m long or around 3.2 m high, read the access notes before following a little brown sign into scrub.

The Nullarbor is famous for being empty, but it is not quiet. Road trains up to about 53.5 m use this corridor, and they do not stop or swerve like a hatchback. Give them room, especially when they are overtaking or throwing wind wash across your lane.

The 90 Mile Straight between Caiguna and Balladonia is about 146.6 km without a proper bend. It is oddly mesmerising for the first half-hour, then your brain starts inventing shapes in the bitumen. Swap drivers, take breaks, and do not let cruise control turn you into furniture.

• Keep left and hold a steady line when a road train passes.
• Only overtake when you can see a very long, clear stretch — out here that still may not be enough.
• Use headlights in glare, rain, dust and late afternoon.
• Avoid dawn, dusk and night driving; animal strikes are common and expensive.

Summer days can top 40°C, while winter mornings can sit near 5°C on the plateau. Check tyre pressures cold, keep the fridge vents clear, and give the engine a rest if the temperature gauge starts doing interpretive dance.

At the South Australia–Western Australia border near Border Village, quarantine inspection is real. Fresh fruit, vegetables, honey, plants and some seeds can be taken. Eat it, cook it, bin it before the checkpoint, or enjoy explaining one elderly tomato to a very unimpressed officer.

Fines can run into hundreds of dollars, and the bigger nuisance is unpacking half the van because you forgot what was under the bench seat. Keep food tubs accessible on border day.

• Before Ceduna: stock dry goods, sealed groceries and drinking water.
• Before the border: finish fresh produce and check the fridge drawer.
• After Eucla: restock fresh food when you reach bigger WA towns.

Time is also mildly ridiculous. SA, WA and the unofficial Central Western Time around Eucla can differ by 45 minutes, plus daylight saving can complicate it further. For camp arrivals and roadhouse meals, local clocks beat whatever your phone thinks after two towers and a nap.

There are excellent short detours if you keep the hired-van conditions in mind. Head of Bight is the classic one: about 20 km off the highway, with southern right whales often seen from June to October. Bunda Cliffs lookouts deliver the edge-of-the-continent moment, but access tracks can be corrugated and dusty.

This is where many first big-lappers get tempted by a line on the map. Do not take a 2WD rental motorhome onto Googs Track, beach sand, station tracks or anything marked 4WD. Recovery bills in remote country are not character-building; they are just large.

• Good sealed/short options: Port Augusta waterfront, Wadlata-style history stops, Ceduna foreshore, Head of Bight access road when open.
• Check first: Bunda Cliffs access roads after rain or heavy corrugations.
• Skip in a 2WD van: Googs Track, beach launches, unknown station roads and muddy campground loops.

Once you turn north from Norseman, the country shifts again: salt lakes, mining roads and that unmistakable Goldfields light. Roll into Kalgoorlie with tanks sorted, dust in every hinge, and enough time to park before the evening rush of utes, mine buses and thirsty locals heading bottle-o-ward.
