Coffs Harbour to Alice Springs campervan route for sealed-road wanderers

The most campervan-friendly Coffs Harbour to Alice Springs drive heads inland over the Gibraltar Range, crosses southern Queensland via Goondiwindi and Cunnamulla, then runs the long outback line through Longreach, Mount Isa, the Barkly and Tennant Creek. It is roughly 3,590 km before you roll into Alice Springs, and the road is sealed all the way if you stay on the main highways.

Could you draw a straighter line on a map via dirt roads and station tracks? Of course. A bored chook could. But many hire motorhome contracts ban unsealed roads except short, approved campground access tracks, and the Plenty Highway or Sandover Highway can be rough, remote and very much not the place to learn what a bond excess feels like.

• Best pace: 10 to 14 days, allowing rest days in Longreach, Mount Isa or Alice Springs.
• Minimum pace: 7 to 8 big driving days, but expect early starts and no lazy swims.
• Road surface: sealed highways on this route; avoid dirt shortcuts unless your rental agreement specifically allows them.
• Do: plan around fuel, daylight and heat rather than the blue line on your phone.
• Don't: assume every roadhouse has late opening hours, LPG, potable water or working card facilities.

The first day out of Coffs looks innocent until the Gwydir Highway starts climbing and twisting west of Grafton. In a tall campervan, it is slower than the distance suggests. Let the impatient locals past, use low gears on descents and do not arrive in Glen Innes with your brakes smelling like a burnt toastie.

Past Goondiwindi the towns thin out. Cunnamulla to Longreach is 675 km if done in one haul, which is legal but joyless; Charleville is the sensible pressure valve. Longreach to Mount Isa is another 647 km via Winton and Cloncurry, with long open stretches where 110 km/h feels slower than walking because the horizon refuses to come closer.

• Coffs to Glen Innes: 250 km of coast-to-tablelands climbing; allow 3.5 hours plus stops.
• Goondiwindi to Cunnamulla: about 497 km; refuel at St George rather than gambling.
• Cunnamulla to Charleville: 200 km; a useful laundry, dump-point and stock-up stop.
• Longreach to Winton: 179 km; good early start country before the heat builds.
• Mount Isa to Barkly Homestead: 448 km via Camooweal; fill at Mount Isa and again at Camooweal if range is tight.

A typical 2-berth or 4-berth diesel campervan might use around 12 to 16 L/100 km on this sort of route, more into headwinds or when loaded like you are moving house. A 75 L tank can look like 500 km of range on paper, but out here you should treat half a tank as the new empty. Roadhouses can run out, pumps can be down, and Sunday afternoons have a way of laughing at optimism.

Public dump points are commonly found in larger inland towns and caravan parks along this run: Glen Innes, Moree, Goondiwindi, Cunnamulla, Charleville, Longreach, Winton, Mount Isa, Camooweal, Tennant Creek and Alice Springs are the places to check first. Potable water is usually available at holiday parks and some visitor centres, but never assume a tap near a toilet block is drinking water unless it is signed.

• Carry water: at least 10 L per person per day in hot weather, plus a reserve.
• Fuel rule: top up at every major town once west of Goondiwindi.
• LPG: swap or refill options are better in bigger towns; do not leave it until a tiny roadhouse.
• Toilet cassette: use signed dump points only; bush-dumping is grubby and can attract fines.
• Grey water: some free camps require self-contained vehicles, meaning no water on the ground.

This Coffs Harbour to Alice Springs motorhome road trip suits a mix of powered caravan parks, showground camping, roadhouse sites and the odd legal free camp. The grey nomad grapevine is strong out here, but always check current signage because councils change overnight rules when a nice riverside stop turns into a toilet-paper festival.

In Queensland, national park camping is generally booked online before you arrive, with basic sites often around $7 to $8 per person per night, depending on the park and season. In New South Wales and the Northern Territory, fees and booking systems vary. Free camping is not a right; it is a permission, and the permission usually comes with conditions about stay limits, fires, dogs, generators and being self-contained.

• Powered sites: use them every few nights to charge house batteries properly and run air-con legally.
• Showgrounds: often good value, practical and close to dump points, but events can close them.
• Free camps: arrive early, stay tidy, and do not spread gear like you have annexed the shire.
• National parks: book online, carry confirmation, and keep generators out unless specifically allowed.
• Do: use a proper campsite in Alice Springs if you want showers, laundry and a secure reset before exploring further.

Road trains on the Barkly and Stuart Highway can be over 50 m long and move a lot of air. When one comes towards you, keep left, hold steady and avoid drifting onto the loose shoulder. When one wants to overtake, maintain your speed unless conditions are poor; sudden braking in a big motorhome is not helpful, it is interpretive dance with consequences.

The comfortable season is roughly April to September. Summer is possible, but western Queensland and the NT can sit above 40°C, and sleeping in an unpowered van without air-con becomes less adventure and more slow-cooked regret. The wet season, mainly November to March in the north and centre, can also close roads after storms even when the highway looks fine on yesterday's app.

• Best months: May to August for cooler nights, busy camps and plenty of Big Lap traffic.
• Hot months: December to February can mean 38°C to 45°C days inland.
• Wildlife: avoid dawn, dusk and night driving; roos, cattle and emus do not read hire agreements.
• Tyres: check pressures cold every few days and inspect for sidewall damage after rough shoulders.
• Emergency buffer: carry extra drinking water, snacks and a paper map; reception is patchy outside towns.

You do not need a 4WD to reach Alice Springs by this route, but you do need a van you are comfortable driving for long days. A compact 2-berth is easier in supermarket car parks and windy range roads; a 4-berth or 6-berth gives families more sanity, more water capacity and more indoor space when the flies declare war at sunset.

Check vehicle height before you leave Coffs. Many motorhomes sit around 2.7 m to 3.3 m high, which matters for servo awnings, low branches, car parks and the occasional historic pub verandah that looks higher than it is. If you are planning a one-way hire, book early and check availability online, especially in winter when everyone and their neighbour's retired uncle is pointing a van at the Red Centre.

• 2-berth: nimble, cheaper on fuel, best for couples who pack like adults.
• 4-berth: more storage and indoor space; useful for longer outback stretches.
• Toilet/shower models: handy for self-contained free camps and long roadhouse gaps.
• Air-con: usually needs 240 V power when parked, so plan powered sites in hot weather.
• Rental rule: confirm sealed-road use, one-way permission, after-hours pick-up limits and any remote-area exclusions before booking.
