A Perth to Port Macquarie campervan run across the wide bit

You can physically drive from Perth to Port Macquarie in 7 to 9 long days if you treat the van like a delivery truck and yourself like a slightly underpaid courier. That is not how most people want to remember their Perth to Port Macquarie motorhome road trip.

A sensible self-drive pace is 12 to 16 days. That gives you room for laundry, a powered-site reset, a slow morning in Kalgoorlie, a Nullarbor clifftop stop, and the inevitable servo conversation with someone called Baz who has been doing the Big Lap since 2018.

• Fast but legal: 7-9 days, mostly 500-750 km driving days.
• Comfortable: 12-16 days, with shorter days after the Nullarbor.
• Best for first big-lappers: cap most days at 350-500 km and avoid driving at dawn or dusk.
• Do: book key holiday parks online in school holidays and long weekends.
• Don't: plan a 765 km Nullarbor day if you have never driven a high-roof van in crosswinds.

The direct route uses the Great Eastern Highway, Coolgardie-Esperance Highway, Eyre Highway, Stuart Highway, Barrier Highway, Mitchell Highway and Oxley Highway. It is sealed all the way, so a 2WD campervan or motorhome is fine for the main run.

The Nullarbor section is where distances start to feel Australian. Norseman to Balladonia is about 191 km, Balladonia to Caiguna 181 km, Caiguna to Cocklebiddy 65 km, Cocklebiddy to Madura 91 km, Madura to Mundrabilla 115 km, Mundrabilla to Eucla 66 km, Eucla to Border Village 12 km, then Border Village to Nullarbor Roadhouse about 184 km. Fuel exists, but it is not the place to run the tank down for sport.

• Fuel rule: refill when you drop below half a tank west of Ceduna.
• Cost reality: remote roadhouse fuel can be 30-70 cents per litre dearer than capital-city prices.
• Quarantine: expect fruit, veg, honey and plant checks entering South Australia; eat or bin fresh produce before the checkpoint.
• Do: carry at least 10-20 litres of drinking water per person in hot weather.
• Don't: take unsealed Bight tracks unless your hire agreement specifically allows it.

This route has a workable mix of powered holiday parks, roadhouse campgrounds, council-approved rest areas and showground-style stops. The trick is not finding a place to park; it is knowing which places allow overnight stays and which are daytime rest stops with expensive-looking signs.

Use powered sites every few nights to recharge house batteries, run air-con where permitted, refill water and empty the cassette. Dump points are commonly available in or near Kalgoorlie-Boulder, Norseman, Ceduna, Port Augusta, Broken Hill, Cobar, Dubbo and Port Macquarie, though exact access can change with council works or park rules.

• Free camping: use signed rest areas only, stay within posted limits and leave no grey water or toilet waste.
• National parks: book sites online where required; pets are generally not allowed.
• Roadhouse stops: handy for fuel, meals and showers, but ask before assuming you can camp.
• Do: arrive before dark, especially in kangaroo country.
• Don't: dump cassette waste in toilets, bushes or roadside bins. That is how we lose good stops.

Road trains on the Eyre and Barrier highways can be up to 53.5 metres long. When one passes, keep left, hold a steady line and expect a shove of air. If you are new to a motorhome, that first buffet feels dramatic; by Ceduna you will be giving it a calm little nod like a seasoned grey nomad.

Overtaking needs patience. A campervan is heavier than a car, slower to accelerate and more affected by headwinds. If there is dust, glare or a crest ahead, sit back and wait. The road train driver has a UHF and a timetable; you have a fridge, a bed and no medal for impatience.

• Safe speed: drive to conditions, not just the 110 km/h sign.
• Wind: slow down in crosswinds, especially between Norseman and Ceduna.
• Wildlife: roos, emus, goats and stock are worst around sunrise and sunset.
• Do: pull well off the road at lookouts and rest bays.
• Don't: park on the shoulder for lunch; use a proper bay unless you fancy road-train turbulence with your sandwich.

After Port Augusta, the route turns inland through Broken Hill, Cobar and Dubbo before crossing to the coast at Port Macquarie. The landscape changes from saltbush and long straight roads to wheat towns, red dirt mining country, river flats and finally the forested climb and descent of the Oxley Highway.

Broken Hill to Cobar is about 457 km with long empty stretches and plenty of goats that appear to have no career plan. Dubbo to Port Macquarie is roughly 477 km; the last part brings hills, bends and heavier traffic, so use lower gears on descents and give the brakes a rest.

• Broken Hill to Wilcannia: about 195 km.
• Wilcannia to Cobar: about 262 km.
• Cobar to Nyngan: about 132 km, then Nyngan to Dubbo about 166 km.
• Dubbo to Port Macquarie: allow 5.5-6.5 hours with stops.
• Do: check NSW flood and road reports after heavy rain.
• Don't: assume inland NSW towns have late-night fuel on every corner.

For this trip, comfort matters more than Instagram floor cushions. A toilet and shower are useful if you plan to use remote rest areas. A high-clearance 4WD camper is not necessary for the main sealed route, but a self-contained motorhome makes the Nullarbor and outback NSW far easier.

Summer can push past 40°C on the Nullarbor and around Broken Hill. Winter nights can drop near 5°C inland, while Port Macquarie may feel humid and mild when you finally smell the sea. Air-conditioning, flyscreens, a decent fridge and enough water storage are not luxuries on this run.

• Good minimum fuel range: 400-500 km between fills, with a buffer.
• LPG: swap or refill options are common in larger towns and many servos, but do not leave it until an isolated roadhouse.
• Power: use powered sites every few days if relying on laptops, medical devices or air-con.
• Do: check campervan availability online early for one-way Perth-to-NSW travel.
• Don't: choose the biggest motorhome if you are nervous about narrow town streets and windy highway passing.
