Melbourne to Broome campervan route for self-drivers

The sealed inland run from Melbourne to Broome via Mildura, Port Augusta, Coober Pedy, Alice Springs, Katherine and Kununurra is roughly 5,050 km. Pure wheel-turning time sits around 55 to 60 hours before fuel stops, roadworks, cattle on the shoulder, lunch, laundry, or the inevitable ten-minute debate about where the reusable shopping bags went.

Twelve days is the bare-minimum transit version. Fourteen to sixteen days is workable if you are already comfortable in a motorhome. Eighteen to twenty-four days is better for first big-lappers, because you can sit out a hot afternoon, do a proper shop, and not arrive in Broome looking like a dehydrated tea towel.

• Fast but tiring: 12 days, mostly one-night stops, few detours.
• Sensible: 16 to 18 days, with rest days at Alice Springs, Katherine or Kununurra.
• Enjoyable: 3 weeks, adding Uluru, Mataranka springs or Lake Argyle if your hire conditions allow the roads.

Do not plan 700 km days back-to-back in a high-sided camper. Crosswinds, road trains and late-afternoon glare make the last 100 km feel like unpaid labour.

South of Port Augusta you can be casual. North of Port Augusta, casual becomes expensive. Remote roadhouses close, card systems occasionally sulk, and fuel can cost noticeably more than capital-city prices. Top up before you are under half a tank; this is not the route for fuel-light bravery.

The longest regular sealed-road gaps worth planning around are in the NT and Kimberley. They are not impossible, but they are long enough that a headwind, air-con and a heavy water tank matter.

• Glendambo to Coober Pedy: about 254 km.
• Coober Pedy to Marla: about 234 km.
• Tennant Creek to Elliott: about 255 km.
• Katherine to Timber Creek: about 286 km.
• Kununurra to Halls Creek: about 359 km.
• Fitzroy Crossing to Broome: about 396 km.

Public dump points are commonly found in larger centres such as Mildura, Port Augusta, Coober Pedy, Alice Springs, Tennant Creek, Katherine, Kununurra, Fitzroy Crossing and Broome, often near visitor centres, showgrounds or holiday parks. Fill potable water whenever you see a proper tap signed for drinking water; do not assume every rest-area tap is safe or available in the Dry.

This Melbourne to Broome motorhome road trip can be done on sealed highways in a standard 2WD campervan or motorhome. The temptation is the side roads: gorges, lookouts, station tracks and the famous Gibb River Road. Read your hire agreement before you point the nose at dirt. Many rental motorhomes are not covered on unsealed roads except short access tracks to recognised campgrounds.

Road trains can run up to 53.5 metres and they do not stop like a hatchback. When one comes towards you, hold your line, ease left within the lane and expect wind buffeting. When overtaking, you want a very long, clear view; if you are not certain, stay put and let the ego have a lie down.

• Do: drive mainly in daylight and avoid dawn/dusk when roos and cattle move.
• Do: check tyre pressures when cold, especially after long hot days.
• Do: carry at least 10 litres of drinking water per person as backup, more in summer.
• Do not: drive floodways in the Wet; if water is over the road, wait.
• Do not: park in spinifex or long dry grass near a hot exhaust.

The best season is usually May to September. Expect cold nights around Coober Pedy and Alice Springs in winter, sometimes close to 0°C, then 30°C-plus afternoons as you push north. From November to April the Kimberley can be brutally hot, humid and flood-prone.

Free camping is part of the fun, but it is not a national right to sleep anywhere with a sunset. Councils, national parks and Main Roads all have different rules. Some highway rest areas allow 24-hour stopping; others are rest only, no camping. In towns like Broome, sleeping in beach car parks or suburban streets can earn a fine and zero sympathy.

Mix your nights. Use powered holiday parks after big hot drives, especially from Katherine north where air-con becomes less luxury and more marital aid. Use legal rest areas for simple overnight transits. Use national park campgrounds when you want scenery, but book online where required and remember pets are usually not allowed.

• Powered sites: best for laundry, air-con, battery recharge and proper showers.
• Unpowered sites: fine in cooler southern legs if your fridge and house battery are healthy.
• Free camps: check signage, stay one night if requested, take rubbish out.
• National parks: book ahead, obey generator and fire rules, use dump points outside the park if none are provided.

Grey nomad wisdom applies: arrive before 3 pm if you want shade, face the fridge side away from the afternoon sun, and never leave the dump point hose where the drinking-water hose should be. Humanity has standards.

The NT to WA border near Kununurra is not just a line on the map. Western Australia has quarantine rules, and inspectors may check for fresh fruit, vegetables, honey, plants, seeds and some soil contamination. Eat or dispose of restricted items before the checkpoint rather than trying to explain three sad tomatoes under the bed.

Broome is busy in the Dry season, especially June to August. Powered sites can book out, fuel queues form, and every second van seems to have a red-dust beard. If Broome is your finish point, check availability online for the vehicle and your first couple of nights before you commit to dates.

• Before Kununurra: clean out fruit and veg, empty obvious rubbish, top up fuel.
• At Broome: pre-book a legal campground or holiday park; do not wing it at Cable Beach.
• Before vehicle return: empty toilet cassette, refill fuel as required, sweep out red dirt.

If you have extra days, use Broome as the reward rather than the finish-line collapse: Town Beach for an easy evening, Cable Beach for the famous light show, and a bottle-o run only after the van is parked for the night.
