A practical geelong to broome campervan route for long-haul self-drivers

Geelong to Broome is roughly 4,950 km by the sealed inland route via Mildura, Port Augusta, Coober Pedy, Alice Springs, Katherine and Kununurra. You can technically drive it in 10–12 long days, but that is the sort of plan made by people who have never met a crosswind near Glendambo or a queue at a single-pump roadhouse.

For a geelong to broome motorhome road trip, allow 14 days as the bare minimum and 18–21 days if you want rest days in Alice Springs, Katherine Gorge country and the eastern Kimberley. In summer, temperatures across SA and the NT can sit above 40°C; in the northern Wet, roughly November to April, roads can close after heavy rain even when your map app looks cheerful.

• Best general window: April to September, with cooler inland nights and drier Kimberley roads.
• Hard yakka window: December to February, when 45°C days are possible around Coober Pedy and the Stuart Highway.
• Do: plan driving days around 450–650 km, starting early.
• Do not: arrive in Broome in July assuming caravan parks have spare powered sites. Grey nomads got there first, probably in May.

The sensible campervan line heads north-west from Geelong through western Victoria, across South Australia, up the Stuart Highway, then west across the Victoria Highway and Great Northern Highway. It is all sealed, which matters because most standard campervan and motorhome hire agreements do not allow long unsealed detours such as the Oodnadatta Track, Tanami Road or Gibb River Road.

The country changes slowly, then all at once: wheat silos near Horsham, saltbush beyond Port Augusta, opal dugouts at Coober Pedy, red ranges around Alice, then boabs and hot Kimberley bitumen. Keep the cab tidy and the fridge latched; the corrugations at servo entries can still launch a tomato like a cricket ball.

• Geelong to Mildura: about 535 km via Ballarat and Ouyen; a good first long day without remote-road pressure.
• Port Augusta to Coober Pedy: about 540 km; fuel at Pimba or Glendambo if your tank is modest.
• Alice Springs to Tennant Creek: about 510 km; the Devils Marbles/Karlu Karlu area is a classic overnight stop if booked or permitted.
• Kununurra to Broome: about 1,040 km; split it at Halls Creek and Fitzroy Crossing unless you enjoy arriving with square eyes.

On this route, fuel is available often enough for a 2WD campervan, but not often enough to be casual. Remote fuel can be 30–60 cents per litre dearer than city prices, and roadhouse opening hours can shift with staffing, weather and plain old Outback reality. Fill when you can, especially once you leave Port Augusta.

Useful planning gaps include Coober Pedy to Marla at about 234 km, Tennant Creek to Elliott at about 254 km, Katherine to Victoria River Roadhouse at about 194 km, Kununurra to Warmun at about 198 km, Halls Creek to Fitzroy Crossing at about 290 km, and Fitzroy Crossing to Broome at about 396 km if you do not top up at Willare or another stop. A practical rule is to never pass remote fuel with less than half a tank unless you know exactly where the next open pump is.

• Dump points: plan for public or park dump points in Mildura, Port Augusta, Coober Pedy, Alice Springs, Tennant Creek, Katherine, Kununurra, Fitzroy Crossing and Broome.
• Water: top up at holiday parks and signed potable taps; not every roadhouse tap is drinking water.
• LPG: 9 kg bottle swaps or fills are usually easiest in larger towns; do not expect every small roadhouse to sort it.
• Do: carry 10–20 litres of backup drinking water separate from the van tank.
• Do not: empty grey water in rest areas, creek beds or dusty pull-offs. Councils and rangers are not amused, and neither is the next camper.

Australia is generous to self-drivers, but it is not a free-for-all. Legal free camping is usually in signed rest areas, designated council camps or roadhouse areas that allow overnight stays. In towns, beaches and national parks, assume nothing: signs beat folklore, and a bloke in thongs saying he camped there in 1998 is not a permit.

Powered holiday park sites across this sort of route commonly sit around the $35–$70 mark depending on season, location and rig size, while many basic rest areas are free but have no dump point, no potable water and plenty of road noise. National park campgrounds in the NT and WA often require online booking, and pets are generally not allowed in national parks.

• Good paid-site rhythm: powered site every second or third night for laundry, batteries, showers and a civilised fridge reset.
• Good free-camp rhythm: use signed 24-hour rest areas between towns, arrive before dark, leave no trace.
• Broome warning: dry-season sites book out early, especially June to August.
• Do: arrive at overnight stops by 3–4 pm in remote areas.
• Do not: drive on after dusk for 'just another hour'. Cattle, roos and wandering stock do not use headlights.

Road trains on the Stuart, Victoria and Great Northern highways can be more than 50 metres long. If one catches you, hold your line, ease left only where it is safe, and let it pass. If you are overtaking one, you need a long, empty view ahead; in a loaded motorhome, that means more than a hopeful squirt of throttle and a prayer to the diesel gods.

Heat is the other quiet boss of this trip. Check tyre pressures when cold, keep an eye on engine temperature, and use shade cloth or screens when parked in the north. A van interior can become unpleasantly hot within minutes in 38°C weather, even before you factor in a western sun on the windscreen.

• Road type: sealed highway for the main route, suitable for standard 2WD campervans and motorhomes.
• Dirt-road limits: avoid the Gibb River Road, Tanami Road and long station tracks unless your specific hire agreement allows them.
• Overtaking: wait for clear, straight road and no dust haze; road trains can throw stones and turbulence.
• Do: slow down for floodways even when dry; they can hide dips big enough to rearrange the cupboards.
• Do not: trust a shortcut just because it looks shorter on a screen. In the outback, shorter can mean uninsured.

Broome feels like a finish line: pindan dust, warm evenings, caravans queued like migrating turtles, and Cable Beach sunsets doing their level best to make everyone forget the laundry. Before you switch into holiday mode, empty the toilet cassette, dump grey water where permitted, refill fuel as required by your hire terms, and give the van a basic sweep-out. Red dust is persistent; treat it like glitter with better branding.

One-way campervan hire into Broome can be limited in peak dry-season months, and availability changes quickly around school holidays and major events. If the geelong to broome campervan route is your big westward leg, compare vehicle size, bed layout, onboard toilet/shower needs and one-way rules before locking in dates.

• Smaller campervan: easier in town and cheaper on fuel, but less comfortable for long hot stretches.
• Larger motorhome: better storage, toilet/shower convenience and longer free-camp comfort, but watch height, length and site availability.
• Before handback: dump, refill, clean, check LPG and photograph the vehicle condition.
• CTA: when your dates are firm, book or check availability online rather than waiting until Broome is full and your only option is optimism.
