Adelaide to Geelong campervan route: Coorong, craters and the Great Ocean Road

The quickest Adelaide to Geelong drive is roughly 725 km via the Dukes and Western highways. Fine if your hobby is staring at white lines and overtaking grain trucks. The better adelaide to geelong motorhome road trip is the coastal version: about 970 km and 13 to 14 hours of wheel time before stops.

Five days is the sensible minimum. Seven days lets you sit out bad weather, do laundry, empty the cassette without a panic, and pull over when the Great Ocean Road throws another lookout at you.

• 2 days: possible, but you will miss the point and arrive feral.
• 4 days: workable with nights around Robe, Port Fairy and Apollo Bay.
• 5 to 7 days: the sweet spot for self-drivers sleeping in the van.
• 10 days: add Naracoorte Caves, Cape Bridgewater and extra Great Ocean Road nights.

Do book your first and last nights before you collect the vehicle. Do not assume a coastal carpark is fair game after dark; many SA and Victorian foreshore councils patrol overnight camping, especially in summer.

From Adelaide, point the nose south-east to Tailem Bend and Meningie, then follow the Coorong towards Kingston SE and Robe. From there it is volcanic limestone country to Mount Gambier, then across the border to Portland, Port Fairy and Warrnambool before the Great Ocean Road run through Port Campbell, Apollo Bay, Lorne and into Geelong.

The whole route is sealed and suitable for standard 2WD campervans and motorhomes. The catch is not surface; it is spacing. Adelaide to Tailem Bend is about 100 km, Meningie to Kingston SE is around 145 km, Mount Gambier to Portland is about 108 km, and Port Campbell to Apollo Bay is roughly 98 km of slow scenic driving. Fuel is not remote-outback scarce, but late trading hours can still bite.

• Fill before the Coorong: Meningie is a good top-up before the quieter 145 km to Kingston SE.
• Watch road trains: expect them on the Princes Highway and around grain and timber country; let them pass and leave room.
• Keep the van sealed-road friendly: beach access tracks, dune tracks and soft shoulders are how holidays become recovery bills.

Do take the turnout when traffic stacks behind you on the Great Ocean Road. Do not race the bends in a tall van with full water tanks and cupboards full of tins.

The first night out of Adelaide is often best kept easy: Meningie or a Coorong National Park campground if you are already organised. National-park sites in South Australia and Victoria are generally book-online arrangements, often unpowered, and pets are usually not allowed. Holiday parks cost more, but powered sites, showers, laundries and a legal dump point feel luxurious after a windy beach night.

Useful service towns on this route include Meningie, Robe, Mount Gambier, Portland, Warrnambool, Apollo Bay and Geelong. Public dump points and potable-water taps can change with council works, so check the latest listing before you roll in; never dump grey water or cassette waste into bush, dunes, stormwater drains or campground toilets unless signed for it.

• Good first easy nights: Meningie, Robe or Mount Gambier if you want powered sites and a simple reset.
• Good scenic nights: Coorong National Park, Port Fairy, Port Campbell or Apollo Bay.
• LPG and groceries: Adelaide, Mount Gambier, Portland, Warrnambool and Geelong are the safer bets; small-town servos may shut early.
• Bottle-o logic: buy before the tiny towns, not at 7:55 pm after a long drive.

Do carry drinking water separately from your main tank in hot weather. Do not park overnight under a no-camping sign and hope being self-contained makes you invisible; it does not.

The Coorong section is big-sky driving: low scrub, saltwater, long straights and the sort of side wind that reminds you a campervan is shaped like a brick. In summer, expect 30 to 40°C days inland from the coast; in winter, expect rain, southerlies and damp towels that never quite forgive you.

Robe is a tidy stop for powered sites, seafood and a leg stretch, but be careful with beach-driving temptations. Many hired campervans are not permitted on beaches, unsealed 4WD tracks or sand, even if a local ute makes it look easy. Mount Gambier is a practical hub: supermarkets, fuel, laundries, dump points and the Blue Lake, which is at its famous cobalt best from roughly November to March.

• Meningie to Robe: about 200 km, allow 2 hr 20 plus Coorong stops.
• Robe to Mount Gambier: about 130 km, allow 1 hr 35 via Beachport or the main road.
• Fuel habit: top up at Robe or Millicent rather than arriving at Mount Gambier on fumes.

Do check fire danger ratings in summer; total fire bans can affect camp cooking outside the van. Do not drive after dusk if you can avoid it: kangaroos and wombats are considerably less worried about your excess than you are.

From Port Fairy and Warrnambool, the road swings into the famous limestone coast: Bay of Islands, London Bridge, Loch Ard Gorge and the Twelve Apostles. The carparks are built for tourism, but summer and school holidays still fill them early. A 6 to 7.5 m motorhome is fine if you arrive patiently and avoid squeezing into tiny roadside gravel bays.

The Port Campbell to Apollo Bay stretch is only about 98 km, yet it can take two hours without sightseeing. Add lookouts, coffee, weather and photo queues and it becomes a full day. East of Apollo Bay, the road tightens through Lorne and Anglesea before opening up towards Torquay and Geelong.

• Best driving window: early morning for easier parking and less convoy traffic.
• Height/length: standard hire campers are generally okay on the sealed route; check your vehicle height before servo canopies and holiday-park trees.
• Overnighting: use booked campgrounds or holiday parks; Great Ocean Road carparks are heavily signed and patrolled.
• Surf-coast etiquette: do not use beach showers for dishes, cassette rinsing or your entire van spring-clean.

Do let locals and quicker cars pass when a turnout appears. Do not tailgate a road train, milk tanker or nervous rental car; all three can ruin your day in different ways.

Spring and autumn are the easiest seasons for this run: mild driving weather, fewer crowds and campsites that are not booked solid by everyone from grey nomads to first-big-lappers. Summer brings longer evenings, but also heat, fire bans and very busy beach towns. Winter can be moody and excellent, provided you are happy with wind, rain and powered-site heater time.

If you are doing a one-way hire, confirm Adelaide pickup and Geelong or Melbourne-area drop-off availability before you build the whole itinerary. Vehicle sizes, minimum hire periods and one-way rules vary by date, especially around Christmas, Easter, AFL finals and school holidays.

• Book ahead: Robe, Port Fairy, Port Campbell and Apollo Bay in peak periods.
• Check online: vehicle availability, one-way options and berth layout before committing to camp bookings.
• Carry range: keep at least a quarter tank between towns; coastal headwinds can lift fuel use.
• Plan dump days: every 2 to 3 days is comfortable for most cassette-toilet setups.

Do leave one flexible night if you can. Do not turn a scenic coastal route into a delivery run just because the map app says it is only another 90 minutes.
