Campervan dump points and water Australia: the unglamorous bit that saves trips

On night one, most new van travellers worry about the bed. By night three, they are quietly more interested in the toilet cassette. A typical hire camper has a 15–20 litre toilet cassette, a 60–100 litre grey-water tank and roughly 70–120 litres of fresh water, depending on size and layout.

Two adults using the onboard toilet, sink and a quick shower can often go 2–3 days before needing a dump point. In hot country, plan drinking water separately: 3–5 litres per person per day is sensible, more if you are walking, travelling with kids, or crossing places where the map looks empty because it is.

• Do: top up fresh water when it is easy, especially before long inland legs.
• Do: empty the cassette before it is completely full; a sloshing full cassette is no one’s finest hour.
• Don’t: assume every tap is drinking water. Look for “potable water” signage.
• Don’t: tip grey water onto the ground unless the site specifically allows it.

Dump points are not glamorous, but Australia is better set up for them than many first-timers expect. You will find them at many holiday parks, council RV stops, showgrounds, visitor centres, selected servos, roadhouses and some public rest areas. Some are free; others ask for a gold coin donation or a small fee, commonly around $5–$10 if you are not staying there.

Water is trickier. Coastal towns usually make it easy. Remote roadhouses may ration it, charge for it, or have bore water that is fine for washing but not ideal for drinking. Across the Nullarbor, up the Stuart Highway or through the Kimberley, ask before you connect a hose and do not hog the tap while someone behind you is trying to fill a kettle and escape the flies.

• Best bets: holiday parks, RV-friendly towns, council dump points and major roadhouses.
• Ask first: at servos, caravan parks where you are not staying, and remote properties.
• Carry: your own drinking-water hose and a few hose fittings.
• Avoid: rinsing your water hose anywhere near a dump-point splash zone.

Free camps are one of the great joys of a Big Lap: a creek bed outside a tiny town, a dusty rest area full of road-train rumble, or a coastal pull-in where the morning kettle tastes better than café coffee. But “free” does not mean “do what you like”. Many councils now require vehicles to be self-contained, which generally means onboard toilet, sealed grey-water storage and no wastewater on the ground.

National parks vary by state and park. Some campgrounds have toilets but no dump point. Some require online booking before arrival, even if the road in is corrugated and the ranger is 80 km away. Chemical toilet waste must go into an approved dump point, never a pit toilet, long-drop, stormwater drain, creek or beach access track.

• Do: read the sign at the camp entrance before setting up awnings and chairs.
• Do: use a sealed grey-water tank where required.
• Don’t: leave food scraps, toilet paper or shower water behind.
• Don’t: rely on “everyone else is doing it” as a legal strategy.

Australia does not do small gaps politely. Port Augusta to Coober Pedy is about 540 km. Ceduna to Norseman across the Nullarbor is roughly 1,200 km if you string the roadhouse hops together. Katherine to Kununurra is about 514 km, and in the build-up the air can feel like someone parked you inside a wet towel.

Inland summer temperatures can sit above 40°C. The Top End wet season, roughly November to April, can close roads and turn a creek crossing into a trip-ending insurance argument. If your hire agreement says sealed roads only, treat dirt-road dump points and bush camps as off-limits unless your vehicle category and terms allow them.

• Water buffer: carry at least 20 litres extra for remote legs.
• Fuel habit: fill at the servo before the gauge gets dramatic; not every map dot sells fuel.
• Road trains: give them room at roadhouses and rest areas; they are working, you are making toast.
• Heat rule: never drain your fresh tank “because the next town is close” unless you know the next tap is working.

Dump-point etiquette is simple: be quick, be clean, and do not treat the place like a science experiment. Park so others can still move around you, put on disposable gloves, empty the cassette slowly, rinse only with the dump-point hose if provided, and secure the cap properly before walking back to the van.

Fresh water needs the opposite treatment. Use a dedicated drinking-water hose, keep the ends off the ground, and store it away from the toilet gear. If a tap is marked non-potable, it is for rinsing or washing only. If there is a queue, fill what you need and move on; the bloke behind you may have 300 km to cover before dark.

• Do: keep toilet chemicals, gloves and cassette gear in a separate tub.
• Do: check the grey-water drain valve is shut before driving off.
• Don’t: use the drinking-water tap to rinse a toilet cassette.
• Don’t: leave the dump point messy for the next van; that is how facilities disappear.

A city-to-coast weekend does not need the same setup as a six-week run through the Centre. Before you book, check whether the campervan has a toilet, shower, grey-water storage, fresh-water capacity and the right road permissions for your route. Smaller campers may have a portable toilet or no bathroom at all; larger motorhomes usually give you more tank capacity and more comfort, but they are taller, longer and thirstier.

Vehicle height matters at old holiday parks, city car parks and low tree-lined campsites. Length matters at national-park bays and ferry bookings. LPG is a separate system for cooking, hot water or heating in many vans, so do not confuse a gas refill with a water fill. When comparing layouts, think less “brochure breakfast table” and more “where does the wet hose live after 500 km of red dust?”

• Do: match tank capacity to your camping style before you check availability online.
• Do: choose a self-contained setup if you want more free-camp options.
• Don’t: book a compact van and assume it has a toilet or grey-water tank.
• Don’t: take a sealed-road hire camper onto restricted dirt tracks chasing a remote dump point.
