Winter is a great time to travel around Australia. The roads are quieter, the parks are less crowded, and it’s lovely to wake up on a frosty morning with a hot cup of tea in your hands.
Winter can also be hard on you and your caravan, though. Nights get very cold, especially inland and up in the mountains. Some places drop below zero.
The good news is that a little planning makes a big difference. In this guide, we will go through simple steps to get your caravan ready for winter. We will also look at the gear that makes cold trips safe and comfortable.
Why Winter Caravanning Needs Extra Planning
Australia is a big country, so winter looks different depending on where you go.
In Queensland and the Top End, winter days are warm and dry. But in places like the Snowy Mountains, the Victorian High Country, Tasmania and Canberra, nights can be freezing. Even parts of inland NSW get frost overnight.
Cold weather affects almost everything in your van. Batteries drain faster. Water pipes can freeze. Windows fog up. And you need to stay warm without running out of power or fuel.
Let’s take it one step at a time.
Step 1: Give Your Caravan a Pre-Trip Check
Before any winter trip, give your van a good look over. Small problems can turn into big ones when it is cold and wet.
Check the Tyres and Brakes
Winter roads can be wet, icy or covered in leaves. Make sure your tyres have plenty of tread and the right air pressure.
Cold air makes tyre pressure drop, so check them again on chilly mornings. It’s also a good idea to have your brakes and wheel bearings checked before you go.
Look for Leaks and Gaps
Check the seals around windows, doors, hatches and the roof. If rain gets in, it can cause mould and damp beds. If cold air gets in, your van will be much harder to heat.
Replace any cracked or worn rubber seals before you leave.
Test Your Lights
Winter days are short. You will often be driving or setting up in the dark. Make sure all the lights on your car and van are working.
Step 2: Choose a Safe Way to Stay Warm
Heating is the most important part of winter caravanning. Getting it right keeps you comfortable. Getting it wrong can be dangerous.
What Is a Caravan Diesel Heater?
A caravan diesel heater is one of the most popular ways to heat a van in Australia. It burns a small amount of diesel to make warm, dry air, which is blown into your van through a vent.
The exhaust fumes go outside through a pipe. Because nothing is burning inside the van, it is much safer than other ways of heating.
People like diesel heaters because they use very little fuel. Many can run all night on a litre or two, depending on the model and setting. They also make dry heat, which helps reduce dampness inside.
Choosing a Diesel Heater Kit
If your van doesn’t have a heater, you can buy a diesel heater kit. A kit usually comes with the heater, a fuel tank, a fuel pump, ducting, an exhaust pipe and a controller.
Here are a few things to think about:
- Installation. A fixed heater should be installed by a qualified person. The exhaust must be sealed properly and vent outside.
- Portable or fixed. Portable diesel heaters sit outside the van and blow warm air in through a duct. Fixed ones are mounted under the van or in a storage locker.
- Altitude. Some heaters struggle high in the mountains where the air is thin. If you are heading to alpine areas, look for one with a high altitude setting.
- Power use. The heater needs a little 12V power to run its fan. It uses the most power when it first starts up.
Use Alpine Diesel in Very Cold Places
Here is a tip many people don’t know. Normal diesel can turn thick and waxy in freezing weather, and that can block your heater’s fuel line.
In alpine areas, service stations sell “alpine diesel” during winter. It is made to stay runny in the cold. Use it in your heater tank when you head to the snow.
Never Heat Your Van the Wrong Way
Never use a gas cooktop, gas oven or outdoor gas heater to warm the inside of your van. They make carbon monoxide, a gas you can’t see or smell. It can make you very sick, and it can even kill.
Get a Carbon Monoxide Alarm
Even with a well-installed heater, a carbon monoxide (CO) alarm is a must. It is small and cheap, and it beeps loudly if something goes wrong. Test it before every trip, just like your smoke alarm.
Step 3: Keep the Heat In
Heating your van is only half the job. You also need to stop the warmth from escaping.
Cover Your Windows
Windows lose a lot of heat. Insulated window covers or reflective screens make a big difference. Thick curtains help too. Close them as soon as the sun goes down.
Block Draughts
Put a draught stopper at the bottom of your door. Close roof hatches at night, but leave one vent open a little. You always need some fresh air, especially when a heater is running.
Add Annex Walls or a Van Skirt
If you are staying in one spot for a while, annex walls help block the wind. A skirt around the bottom of the van stops cold air flowing under the floor, which keeps your feet much warmer.
Step 4: Plan Your Power
Cold weather is tough on batteries. Short days mean your solar panels make less power, and you use more lights and run the heater fan.
Here are some ways to help:
- Check your batteries before you leave. Some lithium batteries don’t like charging below freezing, so read what the maker says.
- Tilt your solar panels toward the sun if you can. Winter sun sits lower in the sky.
- Carry a portable solar panel you can move as the sun moves.
- A DC to DC charger lets your car charge the van battery while you drive.
- Use LED lights. They use much less power.
Step 5: Stay Cosy at Night
A good night’s sleep makes the whole trip better.
Warm Bedding
Pack warm doonas, flannelette sheets and sleeping bags rated for cold weather. Wool blankets are great because they stay warm even when they are a bit damp.
12V Electric Blanket
A 12V electric blanket warms your bed before you hop in. Most have a timer. Switch it off once you fall asleep to save battery power.
Hot Water Bottles
They’re old-fashioned, but they still work! Fill one before bed and put it at your feet.
Step 6: Plan Your Toilet Trips
Nobody likes walking to the toilet block at 2am when it is three degrees outside. In the dark, on wet grass, it can also be slippery and unsafe.
Why a Portable Toilet Helps
A portable toilet means you can stay warm inside your van. Many vans don’t have a built-in toilet, so a small portable one is a smart thing to bring.
It also helps with free camping. Some campsites only allow fully self-contained vans, which usually means having a toilet on board. Check the rules for each place you visit.
Using a Portable Toilet the Right Way
- Use proper toilet chemicals to break down waste and stop smells.
- Only use quick-dissolving toilet paper.
- Empty it only at approved dump points. Never empty it in the bush, in rivers or down normal drains.
- Use a camping app or local council websites to find dump points on your route.
In very cold areas, keep the toilet inside the van so its water doesn’t freeze.
Step 7: Protect Your Water Supply
Water can freeze overnight in alpine areas. Frozen water expands, and that can crack pipes, taps and even tanks.
To help stop this:
- Wrap exposed pipes in foam insulation.
- Keep some drinking water inside the van overnight.
- If it will drop well below zero, drain your water lines when you aren’t using them.
- Leave cupboard doors near pipes open so warm air can reach them.
Step 8: Fight Condensation
When you breathe, cook and shower, you add moisture to the air. On cold nights, it turns into water drops on windows and walls. Over time, this can cause mould.
Here’s how to keep it down:
- Open a roof vent a little, even when it’s cold.
- Turn on the range hood fan while cooking.
- Put moisture absorbers in cupboards and under the bed.
- Wipe the windows dry each morning.
- Dry wet clothes and towels outside or in the annex.
Step 9: Drive Safely in Winter
Check Road Conditions
Before you head off, check weather and road reports. Some roads close in winter because of snow or flooding.
Carry Snow Chains When Needed
In some alpine areas of Victoria and NSW, you must carry snow chains during the snow season. The rules can be different in each area, so check before you go.
Practise fitting your chains at home first. It’s much harder with cold fingers!
Drive to the Conditions
Slow down on wet or icy roads. Watch out for black ice in shady spots on cold mornings. Leave extra space between you and the car in front. Try to arrive before dark so you can set up safely.
