The Coffs Harbour to Kalgoorlie campervan route, without the fairy dust

The direct sealed Coffs Harbour to Kalgoorlie drive is about 3,650 km, depending on your exact camp detours and supermarket zig-zags. You can physically drive it in six long days, but that turns the Nullarbor into a blur of servo pies and marital silence. Seven to nine days is the sweet spot for most motorhome travellers.

From Coffs you climb the Great Dividing Range, cut across western NSW, meet the Barrier Highway, then swing through Port Augusta and Ceduna before the Eyre Highway hauls you across to Norseman. From there, Kalgoorlie is a final 188 km north — a short hop by outback standards, which is still two hours of not hitting a roo.

• Fast but sane: 7 days, mostly 450-550 km driving days.
• Comfortable: 9-10 days, with a rest night at Broken Hill or Ceduna.
• Summer warning: Nullarbor and Goldfields days can push 40°C-plus; fridge performance, tyre pressure and water carry matter.
• Winter warning: Kalgoorlie nights can drop near 0-5°C, so pack layers even if Coffs was sweating.

The route below keeps you on sealed highways suitable for most hire campervans and motorhomes. Waterfall Way between Coffs Harbour and Armidale is a proper range climb with bends, fog patches and impatient locals; use lower gears on descents and let faster traffic pass when safe. After Dubbo the country opens out, the horizons stretch, and your fuel gauge becomes more interesting than your playlist.

Do not be tempted by dusty-looking shortcuts unless your hire agreement specifically allows unsealed roads. A 20 km gravel punt around roadworks is one thing; deciding your 2WD motorhome is suddenly a station ute is how bonds go missing.

• Coffs to Tamworth: mountain grades and slower going; do not plan a late start.
• Dubbo to Cobar: top up at Nyngan if you are below half a tank.
• Cobar to Broken Hill: the Cobar-Wilcannia stretch is about 260 km with limited backup.
• Ceduna to Norseman: split it over two or three days unless you enjoy becoming furniture.

The longest practical fuel gaps on this route are not 600 km horror stories, but they are long enough to punish lazy planning. Between Cobar and Wilcannia is around 260 km. Across the Nullarbor, common roadhouse gaps include Ceduna to Penong at about 75 km, Nundroo to Nullarbor Roadhouse around 143 km, Nullarbor to Border Village about 184 km, and Balladonia to Norseman around 193 km.

Roadhouse fuel is often noticeably dearer than town fuel, because trucking diesel to the edge of nowhere is not a charity event. The smart move is boring: fill at major towns, keep the tank above half once west of Cobar, and carry drinking water separately from your onboard tank.

• Road trains: they can be 50 m long; give them room, especially when they overtake.
• UHF channel 40: useful if your vehicle has a radio, but do not rely on it.
• Overtaking: wait for a long, flat, dead-straight view; a motorhome is not a sports car.
• Night driving: avoid it. Kangaroos, emus and wandering stock do not care about your itinerary.

This is a good route for mixing powered sites with budget stops. Use powered holiday parks or showgrounds every second or third night to recharge batteries, run the air-con legally, shower properly and reset the van. Between those, signed rest areas and roadhouse camps can work well for self-contained travellers.

Public dump points are commonly available in larger stops such as Tamworth, Dubbo, Cobar, Broken Hill, Port Augusta, Ceduna and Norseman, though access can change with works or events. Do not leave cassette waste in toilets, drains or the bush; apart from being foul, it is the sort of behaviour that gets free camps shut down for everyone.

• Powered site budgeting: many regional powered sites sit roughly in the $35-$60 per night band, varying by season and facilities.
• Water: refill where it is signed potable; not every tap at a rest area is drinkable.
• LPG: larger towns are your safer bet; do not assume every Nullarbor roadhouse can swap your exact bottle.
• Free camping: use signed rest areas or permitted camps only, and leave no grey water puddle under the van.

The WA border quarantine check near Eucla is real. Fresh fruit, vegetables, honey, seeds, plants and some other products can be restricted, so eat your apples before the border or donate them to the bin of regret. Inspectors have seen every version of the hidden-tomato trick.

National parks and conservation areas also have their own rules: camp only in designated areas, obey fire bans, book where required, and assume dogs are not allowed unless the park says otherwise. In towns, a quiet kerb does not automatically mean free camping is legal; councils can and do fine overnight camping in prohibited areas, often around beaches, boat ramps and town centres.

• Do: check campsite signs before levelling the van.
• Do: carry 10-20 litres of separate drinking water for the long western sections.
• Do not: drive onto salt lakes, station tracks or beach access in a standard hire motorhome.
• Do not: assume phone coverage between roadhouses; download maps before Ceduna.

A compact campervan can do this run, but a shower-toilet motorhome makes the long gaps easier, especially if you plan to use free camps or arrive after caravan park office hours. Height matters too: supermarket carparks, low trees and older servos can be awkward in taller vehicles, so know your clearance in metres before you leave Coffs.

If this Coffs Harbour to Kalgoorlie motorhome road trip is part of a bigger one-way adventure, check availability online early. One-way hires across the country can book out in school holidays, winter grey-nomad season and around major regional events — and Kalgoorlie is not exactly around the corner for last-minute shuffling.

• Best all-round choice: 2-berth or 4-berth self-contained motorhome with toilet and shower.
• Fuel planning: know the tank size and real-world range before Broken Hill.
• Power: ask about house battery, solar and how long the fridge runs off-grid.
• Book mindset: compare vehicles and check availability online before locking in leave dates.
