Canberra to Perth campervan route: the long, sealed way west

The fast version is about 3,700 to 3,800 km, depending on your camp detours, and roughly 42 hours of steering before you add fuel, lunch, laundry, dump points, roadworks and the inevitable servo pie that burns the roof of your mouth. Seven days is possible if you are tidy, early and not precious. Ten to fourteen days is much more civilised.

The sealed, hire-van-friendly line is Canberra to Wagga Wagga, Hay, Mildura, Port Augusta, Ceduna, across the Eyre Highway and Nullarbor, then Norseman to Perth. You do not need a 4WD for this route, but you do need patience, water, and a fuel plan that is better than ‘she’ll be right’.

• Minimum sensible trip: 7 days, with several 500–700 km days.
• Better trip: 10–14 days, with rest stops around Mildura, Ceduna or Esperance if time allows.
• Road surface: sealed all the way on the main route; many scenic side tracks are dirt and may breach hire conditions.
• Do: start early and stop before dusk, when kangaroos and emus get silly.
• Don’t: plan 800 km days in summer heat with kids, bikes and a fridge full of ambitious groceries.

Your first couple of nights feel deceptively green: Murrumbidgee country, Hay Plains, the Murray at Mildura. Then the map thins out. West of Port Augusta the towns are smaller, the sky gets wider, and the words ‘next services 180 km’ start appearing with a straight face.

A good self-drive pattern is holiday park every second or third night for laundry, showers and a powered top-up, then cheaper roadhouse or free-camp nights in between. Powered sites on a big crossing commonly sit around $40–$70 a night, while many roadside rest areas are free but basic: no power, no showers, no bins worth trusting after a hot weekend.

• First easy night: Hay or Mildura, both with proper van parks and dump-point options.
• Before the Nullarbor: Ceduna is the practical reset — groceries, fuel, water, dump point and a last proper bottle-o before the long straight bits.
• Across the plain: roadhouses such as Nullarbor, Border Village, Eucla, Mundrabilla, Madura, Cocklebiddy, Caiguna and Balladonia are fuel-and-sleep lifelines.
• Do: carry at least 10–20 litres of drinking water separate from your van tank.
• Don’t: assume a free camp has potable water; most do not.

The Canberra to Perth motorhome road trip is not one giant empty fuel gap, but it does punish vague planning. On the Nullarbor the longest common roadhouse-to-roadhouse stretch is around 191 km from Balladonia to Norseman, with other gaps often 110–180 km. That sounds modest until you add headwind, air-conditioning, a high-roof motorhome and a heavy right foot.

Fuel on remote highway stretches can be 30–60 cents per litre dearer than city prices, sometimes more when supply is tight. A large motorhome using 14–18 L/100 km can turn a lazy detour into a real bill. Fill when you can rather than when the warning light starts judging you.

• Hay to Mildura: about 295 km, with limited options between bigger towns.
• Port Augusta to Ceduna: about 470 km, with fuel at places like Kimba, Wudinna and Minnipa.
• Ceduna to Nullarbor Roadhouse: about 300 km; top up before leaving Ceduna.
• Caiguna to Balladonia: about 182 km across very open country.
• Balladonia to Norseman: about 191 km, usually treated as the final Nullarbor fuel leg.
• Do: refill by half a tank in remote country if you are unsure of range.

Out here, road trains are not scenery. They are working traffic, often up to 36.5 m and sometimes longer on approved routes. When one overtakes you, hold your line, ease off slightly, and let the bow wave pass. When you overtake one, you need a very long, very clear straight — thankfully the Nullarbor provides a few, though not always when you want them.

High-sided campervans can move around in crosswinds, especially across the Hay Plains and the exposed Eyre Highway. If the van starts wandering, slow down. Arriving alive at 90 km/h beats arriving never at 110 km/h.

• Typical hire van size: around 5–7.7 m long and 2.7–3.3 m high; know your height before fuel canopies and low branches.
• UHF: channel 40 is commonly used by truck drivers, but not every hire vehicle has a radio.
• Shoulders: can be soft or broken; pull fully off only where it is safe and firm.
• Animals: dawn and dusk are peak strike times for roos, wombats, emus and wandering stock.
• Do: take breaks every 2 hours or about 200 km.
• Don’t: sit beside a road train in its spray, dust or blind spot.

Free camping is part of the charm, but it is not a blank cheque to spread out like a travelling garage sale. Councils, national parks and roadhouses all have their own rules. Some rest areas are 24-hour only. Some require you to be self-contained. Some ban fires completely, especially in summer when the country is dry enough to crackle.

Use dump points at proper towns and roadhouses rather than trying to get creative with a cassette toilet. Expect useful dump-point stops around Hay, Mildura, Port Augusta, Ceduna, Norseman and larger Wheatbelt towns such as Merredin. Potable water is often available at caravan parks and some visitor centres, but roadhouse water may be limited or charged.

Before Western Australia, eat or ditch fresh fruit and vegetables. The WA quarantine checkpoint near the border is serious about fruit fly and biosecurity; fines can be much nastier than wasting a few tomatoes. South Australia’s Riverland fruit-fly rules can also affect what you carry around Mildura and Renmark.

• National parks: book and pay online where required; camp only in designated areas.
• Fires: obey total fire bans; gas cookers may also be restricted on severe days.
• Waste: grey water rules vary; never drain near waterways or campsites.
• Quarantine: declare or dispose of fruit, veg, plants, seeds and other restricted items before WA.
• Do: keep the van self-contained and tidy at free camps.
• Don’t: rely on roadside bins for bulky rubbish after crossing half the continent.
