The Broome to Sunshine Coast campervan route, done sensibly

The practical minimum for a Broome to Sunshine Coast motorhome road trip is 10 days, but 12 to 16 days is a much better plan. That gives you room for a hot afternoon off the road, a tyre check, laundry, a proper shop in Katherine or Mount Isa, and one unplanned delay that will absolutely appear because Australia has a sense of humour.

The sealed route runs Broome, Fitzroy Crossing, Halls Creek, Kununurra, Katherine, Tennant Creek, Mount Isa, Winton, Longreach, Charleville, Roma, Dalby and then into the Sunshine Coast via the ranges. It is mostly highway driving, but the distances are big enough to make city habits look silly.

• Comfortable pace: 300–500 km on most travel days, with one or two longer inland days.
• Do: start early and be parked before dusk; roos, cattle and road trains are not romantic after sunset.
• Don't: plan 700 km days back-to-back in 38°C heat and call it a holiday.

You are not crossing the Simpson, but you are still a long way from the next flat white. The biggest regular fuel concern is the Barkly Highway: Tennant Creek to Barkly Homestead is about 210 km, then Barkly Homestead to Camooweal is about 260 km, then Camooweal to Mount Isa is about 188 km. If a roadhouse pump is out, your careful plan becomes a roadside sulk.

Across the Kimberley, Broome to Fitzroy Crossing is about 396 km, Fitzroy Crossing to Halls Creek is about 290 km, and Halls Creek to Kununurra is about 359 km via Warmun. Kununurra to Katherine is about 514 km with Timber Creek and Victoria River Roadhouse in between. Top up more often than your ego thinks necessary.

• Safe campervan fuel range: aim for 500–600 km minimum between fills, more if your vehicle is heavy or you are running the air-con hard.
• Carry: at least 10–20 litres of drinking water per person in the van, separate from the tank.
• Do: fill at Broome, Fitzroy Crossing, Halls Creek, Kununurra, Katherine, Tennant Creek, Barkly Homestead, Camooweal, Mount Isa, Longreach and Roma.
• Don't: assume every map icon means 24-hour fuel; roadhouse hours and card systems can change.

This route suits a mix of powered holiday parks, roadhouse campgrounds, showgrounds and the occasional legal free camp. In hot weather, a powered site every second or third night is worth it for air-con, battery recovery and the chance to stop smelling like a camp chair.

Public dump points are commonly found in bigger service towns such as Broome, Kununurra, Katherine, Tennant Creek, Mount Isa, Longreach, Charleville, Roma and around Gympie or the Sunshine Coast. Use a dump point app or council listing on the day; do not leave toilet cassette decisions until the red light is blinking and everyone is pretending not to notice.

• Typical site costs: free camps $0, basic roadhouse/showground sites often modest, powered holiday parks commonly around $40–$70 per night depending on season and facilities.
• National parks: book ahead where required, stay only in designated campgrounds, and check generator rules.
• Do: refill potable water whenever you find a reliable tap.
• Don't: empty grey water or toilet cassettes in rest areas, drains or bushland; fines and filthy looks both apply.

Road trains out here can be 53.5 metres long and they move with purpose. When one comes up behind you, hold your line, ease left only when it is safe, and let the professional do the passing. If you overtake one, make sure you can see a very long way ahead; this is not the place for heroic little bursts.

The best broad window is May to September: cooler nights, more reliable road access and less tropical nonsense. From November to April, the Kimberley and Top End sections can be brutally hot, humid and prone to flooding. Even sealed highways can close after big rain, and some side roads become rental-contract trouble in minutes.

• Temperatures: inland sections can top 40°C in late spring and summer; winter nights inland can still surprise you.
• Speed limits: WA and Queensland highways are often 110 km/h; parts of the NT allow 130 km/h, but your hired motorhome may not feel clever at that speed.
• Do: check tyre pressures cold, including the spare if supplied, before the long inland legs.
• Don't: take a 2WD hire camper onto the Gibb River Road, dirt sections of the Savannah Way or station tracks unless your rental agreement clearly allows it.

After Mount Isa the trip changes character. The country softens through Winton and Longreach, then rolls south-east through black-soil plains, pub towns and grain country. By Roma and Dalby you are back among heavier traffic, more frequent fuel, and drivers who have forgotten how wide a motorhome feels.

The final run into the Sunshine Coast may involve Toowoomba, Kilcoy, the D'Aguilar Highway and Bruce Highway traffic depending on your chosen finish. Watch height limits at shopping centres, take range descents slowly in a larger motorhome, and book a powered site near the coast before school holidays turn every campground into a game of musical chairs.

• Good final split: Charleville to Roma or Dalby, then Sunshine Coast the next day.
• Beach note: do not drive hire campervans onto sand unless explicitly permitted; most are not.
• Do: check availability online before locking in flights or a one-way hire.
• Don't: arrive on the coast late Friday in peak season expecting a spontaneous powered site with ocean breezes and no neighbours.
