Mighty campervan hire Kimberley: the sealed-road Big Lap slice

The classic self-drive line is Broome to Kununurra on the Great Northern Highway, with a side trip to Lake Argyle if time allows. It is roughly 1,040 km one-way, fully sealed, and still wild enough to make your coffee taste like achievement. You do not need to prove anything by pointing a 2WD camper at the Gibb River Road.

A Mighty campervan Kimberley run works best when you treat the sealed highway as the main event. Derby, Fitzroy Crossing, Halls Creek and Kununurra are not just dots on the map; they are fuel, groceries, dump points, water fills and the difference between relaxed and muttering at the dashboard.

• Do: plan fuel before you leave each town, especially Halls Creek to Kununurra at about 358 km.
• Do: pull well clear when road trains pass; some are 53.5 m long and throw a wall of wind.
• Do not: assume a brown line on the map is allowed under your hire agreement.

You can drive Broome to Kununurra in three long days if your idea of a holiday is sitting upright and chewing servo sandwiches. For a campervan trip where you actually use the awning, cook dinner before dark and sleep somewhere decent, allow 7 to 10 days one-way or 12 to 16 days as a Broome out-and-back.

In a Mighty motorhome Kimberley itinerary, the best nights are often the simple ones: a powered site in Broome to sort the van, a free or low-cost rest area when the distances bite, then a proper caravan park in Kununurra to wash clothes and reset. Dry-season demand is real from June to August, so check availability online early rather than hoping the last powered site has your name on it.

• Fast but fair: 6 nights Broome to Kununurra.
• Comfortable: 9 to 10 nights with Lake Argyle and gorge time.
• Return to Broome: 14 nights minimum unless you enjoy reversing your holiday at highway speed.

The hardest part often is not collecting the keys; it is deciding where to sleep that first night without turning the van into a rummage sale. In Broome, take a powered holiday-park site for night one if you can. Plug in, test the fridge, learn the water pump noises and find out which cupboard hides the cutlery before the Kimberley heat starts judging you.

Free camping is possible along the highway at signed rest areas, but it is not a licence to build a small suburb. Keep it short, tidy and self-contained. In Western Australia, camping where signs prohibit it can attract fines, and national parks have their own booking, generator and pet rules.

• Powered sites: best in Broome, Derby, Fitzroy Crossing, Halls Creek, Kununurra and Lake Argyle.
• Free/rest areas: useful between towns; arrive early in peak dry season.
• National parks: no pets, fees usually apply, and some campgrounds require online booking.

The Kimberley teaches fuel planning quickly. Broome to Derby is about 222 km, Derby to Fitzroy Crossing about 259 km, Fitzroy to Halls Creek about 290 km, and Halls Creek to Kununurra about 358 km. That last one is the stretch where you do not leave town with a casual quarter tank and a hopeful personality.

Expect remote fuel to cost noticeably more than coastal city prices; in the Kimberley it can sit roughly 20 to 60 cents per litre higher, depending on location and supply. Campervans commonly use around 11 to 15 L/100 km, while larger motorhomes can use more, especially into headwinds or with the air-con working hard.

• Carry water: at least 10 litres per person per day in hot weather, more if walking.
• Watch temperature: dry-season days often sit around 30 to 35°C; build the driving day around morning starts.
• Refuel early: servos can have limited hours, and power or supply issues do happen.

The Kimberley is full of famous names that look close on a map and become a contractual headache in real life. The Gibb River Road, Windjana Gorge, Tunnel Creek, Mitchell Falls and the road into Purnululu are unsealed and may be 4WD-only, seasonal, corrugated, flood-damaged or simply not permitted for a 2WD hire camper.

This is where self-drivers need to be boring in the best possible way. Check your rental conditions before you book side adventures, not after you have bounced 40 km down a track listening to every cupboard become a percussion section. If a road is closed after rain, it is closed; the wet season does not care that you have a sunset plan.

• Do: use sealed lookouts, town bases and guided day tours where access roads are unsuitable.
• Do not: drive through floodwater; even shallow water can hide washouts.
• Season note: many unsealed roads are unreliable or closed from roughly November to April.

A good Kimberley campervan day has three quiet victories: fuel in the tank, fresh water on board and the toilet cassette empty. Broome, Derby, Fitzroy Crossing, Halls Creek and Kununurra are your main resupply anchors. Use them even if the gauge says you could probably make it; the word probably has cooked many a Big Lap plan.

Public dump points and caravan-park facilities are commonly available in these towns, but hours and access can change, so check signage and local information on arrival. LPG bottle swaps or refills are generally easiest in larger towns and at bigger servos, not at every roadhouse between boab trees.

• Dump before remote nights: never assume the next rest area has facilities.
• Top up water: ask before filling from taps; potable water is not automatic.
• Stock food: supermarkets thin out outside Broome and Kununurra, so carry 2 to 3 days of simple meals.
