Your Port Macquarie to Kalgoorlie campervan route, without the heroic nonsense

The cleanest port macquarie to kalgoorlie motorhome road trip heads inland through Dubbo, Cobar and Broken Hill, drops to Port Augusta, then follows the Eyre Highway across the Nullarbor to Norseman and north to Kalgoorlie. It is about 3,540 km before detours, supermarket loops, lookout stops and the inevitable wrong turn into a caravan park boom gate.

You can drive it in 7 big days, but that is how people start arguing with their fridge door. A better campervan pace is 10 to 14 days, especially if you want a rest day at Broken Hill, Ceduna or along the Bight.

• Best pace: 350-500 km on driving days, then stop before dusk.
• Road surface: sealed highway all the way on this route.
• Rental reality: do not duck down unsealed tracks unless your hire agreement allows it.
• Navigation: download offline maps before western NSW and the Nullarbor; mobile coverage gets patchy fast.

Do leave Port Macquarie early enough to clear the coast and ranges in daylight. Do not plan your first proper supermarket shop in a tiny roadhouse where a lettuce may cost more emotionally than financially.

The first couple of days feel civilised: green hills, towns close enough, plenty of servos. West of Cobar the gaps stretch, the horizon flattens, and you start understanding why grey nomads discuss fuel range the way other people discuss grandchildren.

The biggest psychological shift is not the Nullarbor itself; it is the long, straight rhythm from Cobar to Broken Hill and then the wide-open run to Port Augusta. Keep water in the van, keep snacks within reach, and swap drivers before anyone gets the thousand-yard stare.

• Port Macquarie to Dubbo: about 530 km via Tamworth/Gunnedah country; allow 6-7 hours plus breaks.
• Cobar to Broken Hill: about 456 km, with Wilcannia roughly 260 km from Cobar.
• Ceduna to Eucla: about 493 km; this is where roadhouses replace suburbs.
• Balladonia to Kalgoorlie: about 386 km via Norseman; top up before turning north.

Do treat the listed drive times as steering-wheel time only. In a campervan, add at least 20 minutes per fuel stop and more if you are emptying a cassette, filling water and explaining to someone from Europe that, yes, the next town really is 190 km away.

On paper the fuel gaps are manageable. In practice, wind, heat, roof height and a heavy water tank can push a motorhome from 11 L/100 km to 14 L/100 km or more. Aim to refuel by half a tank once you are west of Cobar, not when the warning light starts composing its farewell speech.

Road trains are normal out here, especially west of Broken Hill and across the Eyre Highway. They can be 36.5 m long, throw a proper bow wave, and need more room than your average hatchback caravan tango at a coastal servo.

• Longest useful fuel gap: Cobar to Wilcannia is roughly 260 km.
• Nullarbor gaps: Penong to Nullarbor Roadhouse is about 219 km; Balladonia to Norseman about 191 km.
• Fuel habit: fill at Cobar, Broken Hill, Port Augusta, Ceduna, Eucla or Border Village, Balladonia, Norseman.
• Passing: if a road train is coming past, hold your line, ease off slightly, and do not drift onto the gravel shoulder.

Do carry at least 10 litres of drinking water per person as a reserve, separate from the van tank. Do not rely on every roadhouse having cheap fuel, fresh water, LPG, a dump point and a smile all on the same Tuesday afternoon.

This route is friendly to self-contained travellers, but it is not a free-for-all. Towns such as Cobar, Kimba, Ceduna, Norseman and Kalgoorlie have a mix of caravan parks, low-cost RV areas and public dump point access, while national parks and reserves have their own rules. If a sign says no camping, it means you as well, even if your van has fairy lights.

Powered holiday park sites commonly sit around the $40-$70 per night mark depending on season, location and rig size. Free camps can be brilliant for a quiet night, but arrive with your own water, take rubbish out, and use dump points properly. Grey water on the ground is not charmingly rustic; it is how camps get shut.

• Good dump-point towns: Dubbo, Cobar, Broken Hill, Port Augusta, Ceduna, Norseman and Kalgoorlie usually have public or park options.
• Water fills: use signed potable taps only; some Nullarbor water is limited or paid.
• LPG swaps/fills: easiest in larger centres before Ceduna and after Norseman.
• National parks: book where required, use designated sites, and expect no dogs in many parks.

Do plan your toilet cassette around towns, not desperation. Do not assume a remote overnight pull-off is legal just because three other vans are already there and someone has put out a camp chair like a land claim.

The Nullarbor is not difficult if you respect it. The Eyre Highway is sealed, roadhouses are spaced for real travellers, and the cliffs along the Great Australian Bight are worth every fly that tries to move in with you. The traps are simple: heat, fatigue, border quarantine and overconfidence.

Entering Western Australia, quarantine officers check for fruit, vegetables, honey, plants and some other restricted items. Use up fresh food before the border or bin it where directed. There is also the odd 45-minute time-zone shuffle around the border, which is exactly as annoying as it sounds when you are trying to arrive before reception closes.

• Summer: expect 35-45°C days inland; avoid long roadside stops in the heat.
• Winter: nights can drop near 5°C around the interior and the Nullarbor.
• Wind: strong crosswinds can push high-roof vans; slow down and keep both hands on the wheel.
• Wildlife: kangaroos, emus and stock are most active at dawn and dusk. Park up before then.

Do carry a printed note of your hire roadside-assistance process and vehicle height. Do not drive at night to “make up time”; out here, that is not efficient, it is just gambling with fur-covered speed bumps.

A Port Macquarie to Kalgoorlie drive rewards a van that is comfortable at highway speed, has decent fuel range and gives you enough living space for weather days. A small campervan is easier in towns and cheaper at the bowser; a larger motorhome gives you an onboard shower/toilet and better self-containment for remote stops.

Before you book, check bed setup, fridge size, fuel type, included kilometres, roadside cover, vehicle height and whether the vehicle is allowed on sealed highways only. The Eyre Highway is fine for standard campervans, but side tracks to beaches, lookouts or station stays may not be.

• Solo/couple: compact or 2-berth campervan, especially if you prefer holiday park amenities.
• Two who like space: 2-berth motorhome with toilet/shower for easier free-camp nights.
• Family: 4-6 berth motorhome, but watch length at older caravan parks and fuel use in headwinds.
• Must-have: enough freshwater capacity and a toilet solution for long stretches between towns.

Do compare layouts before locking in dates; the cheapest van is rarely the best van if you are crossing half the continent. When your dates are set, check availability online and book the campervan that matches how you actually travel, not how heroic you feel on the couch.
