Campervan Australia in December: heat, holidays and where to park

Australia in December is not one climate; it is a continent having several moods at once. Melbourne and Adelaide can sit around 24–30°C, Hobart is often a civilised 18–23°C, Perth and the south-west can push 30°C, while Darwin and Cairns bring 28–33°C with humidity that makes your towel feel like a damp handshake.

The north is entering the wet season. That means afternoon storms, possible road closures, marine stingers, swollen creeks and cyclone watch-and-wait from November to April. A two-wheel-drive hire camper should not be treated like a fishing ute, especially on red dirt after rain.

• Do: start driving early, park in shade by mid-afternoon, and keep at least 10–20 litres of drinking water on board.
• Do: check state fire bans daily; Total Fire Ban rules can change what cooking is allowed.
• Do not: assume a short unsealed road is fine in a hire vehicle. Many rental conditions limit dirt-road use, and wet gravel can close fast.

From roughly 20 December to the end of January, the east coast, south-west WA, Tasmania, the Great Ocean Road and anything with a patrolled beach fill with school-holiday families, grey nomads and first big-lappers who all had the same clever idea. Powered sites near the water can disappear months ahead; unpowered overflow areas may still require online bookings.

If you are collecting a van in Sydney, Melbourne, Brisbane, Perth, Adelaide or Hobart, plan your first two nights before you land. The hardest first-night lesson is not driving the vehicle; it is finding a legal place to sleep after dark when the holiday park says full and the council ranger knows every cheeky lay-by.

• Book ahead: Christmas week, New Year’s Eve, ferry-linked Tasmania, and coastal national parks.
• Keep flexible: inland towns 30–80 km from the beach often have quieter showgrounds or caravan parks.
• Budget reality: peak-season powered sites can be noticeably dearer than shoulder season, and some parks add minimum stays.

The best December routes are not always the hottest headline trips. The Red Centre is magnificent, but 38–43°C around Alice Springs and Uluru is not romantic when your fridge is battling, the flies are unionised, and you are rationing shade. Save the deep outback for cooler months unless you are very prepared and have wide fuel and water margins.

For December, chase sea breezes, forest shade and shorter driving days. Tasmania, Victoria’s coast, the NSW Sapphire Coast, South Australia’s Fleurieu Peninsula and Western Australia’s south-west all let you build a good loop without 700 km slogs between swims.

• Tasmania: cooler nights, strong demand, excellent national park camping if booked where required.
• Great Ocean Road: busy but practical from Melbourne, with many powered-site options.
• South-west WA: Margaret River, Denmark and Albany give beaches, tall trees and less tropical misery.
• NSW South Coast: good for a Sydney or Canberra pickup, but book early from Jervis Bay to Eden.

December driving is about fatigue management as much as scenery. Long daylight tempts people into silly kilometre days, but heat, glare, caravans, roadworks and holiday traffic slow everything down. On single-lane highways, a road train can be over 50 metres long; give it room, do not sit in spray or dust, and never overtake unless you can see a very long way ahead.

In populated coastal areas fuel is easy. Head inland and the map becomes more honest. In parts of western NSW, SA, WA and the NT, sensible drivers refuel when the tank hits half, not when the warning light starts sulking. Around public holidays, smaller servos may run reduced hours.

• Range rule: plan fuel stops every 250–350 km in remote country, even if the vehicle can go further.
• Water rule: refill whenever you see potable water; not every dump point has drinking water.
• Heat rule: check tyre pressures cold, and do not ignore a dashboard warning because the beach is only 40 km away.

Free camping is not a national free-for-all. Councils set local rules, national parks require bookings or permits in many places, and sleeping overnight in a day-use car park can earn a fine that ruins the smug glow of saving a site fee. If a sign says no camping, believe it; rangers are not there for interpretive theatre.

December also tests self-containment. A camper with a toilet cassette, grey-water rules understood, and a planned dump point every few days gives you more options. Empty cassettes only at signed dump points, never in bush toilets, stormwater drains or the scrub. Yes, people do this. No, we are not proud of them.

• Do: use official apps, council pages and national park booking systems before arriving.
• Do: carry a 10 amp lead only if your hire vehicle is set up for powered sites, and use approved connections.
• Do not: run a generator in a quiet campground unless rules explicitly allow it; December neighbours are already warm enough.

Pack for sun, storms and crowded laundries. You do not need half a camping shop, but you do need the boring things that stop a good trip turning into a servo car-park negotiation: shade, water storage, mozzie defence and a tidy plan for wet towels.

For self-drivers, the small kit matters because the van is your transport, kitchen, bedroom and sanity bunker. Keep heavy items low, do a quick walk-around before leaving camp, and never drive off with the roof vent up unless you enjoy expensive confetti.

• Wide-brim hat, SPF 50+ sunscreen, sunglasses and long-sleeve sun shirt.
• Insect repellent, especially for wetlands, rivers and northern camps.
• Refillable water bottles plus backup water in the vehicle.
• Light bedding for warm nights, but a jumper for Tasmania, alpine areas and windy coasts.
• Cards, head torch and patience for Christmas queues at the bottle-o and supermarket.
