How to find a dump point (and use one without being that person)

My daughter asked me, at full volume in a very quiet camp kitchen, why our van had a "poo pipe". I've thought about that moment often since, because honestly, it's a fair question. Dump points are one of those things nobody explains before you hit the road — you just sort of figure it out as you go, usually under mild panic when the tank gauge is reading full and you're three days from a powered site.

After four years of east coast touring with two kids, a kelpie cross, and a van with a 90-litre cassette toilet plus a 120-litre grey water tank, I've used a lot of dump points. Good ones, bad ones, ones I've had to locate in a hurry on a Sunday afternoon in a town of 400 people. Here's what I've learnt.

What a dump point actually is (quick recap)

A dump point is a designated disposal station for cassette toilet waste (black water) and sometimes grey water. They're usually a recessed pit in the ground with a lockable lid, a water tap for rinsing, and — if you're lucky — a hose and a bin for your gloves. Some have signage. Some are just a hole in the concrete with a small blue sign bolted to a fence post.

Councils, caravan parks, national park campgrounds, roadhouses and rest areas all operate them. There is no single national authority — management sits with local councils and relevant state land managers, which is exactly why standards vary so much.

How to find one before you need one

The two apps I use most are Wikicamps and Camps Australia Wide. Both let you filter specifically for dump points, which means you can plan your route around them when you know the tank is getting full. I've written more about the broader apps worth having in our caravan and camping apps guide — but for dump points specifically, Wikicamps has the more frequently updated user-submitted listings in my experience.

The dumppoints.com website is also genuinely useful — it's a community-maintained database that lets you search by town or postcode and even check recent user comments about whether a point is currently open and functional. I check it whenever I'm rolling into an unfamiliar town.

One thing I do at the start of every trip: I screenshot or download offline maps for the corridor we're travelling, because mobile data is not guaranteed once you're north of Rockhampton or west of pretty much anywhere. Don't assume you'll be able to search live when you need it.

Who can use them, and do they cost anything

Most dump points on public land — rest areas, council facilities, some petrol stations — are free to use. Some caravan parks offer them to non-guests for a small fee, typically $5 to $15. A few roadhouses charge too, which is fair enough given they're maintaining the infrastructure.

Here's what catches people out: some dump points are locked and require a key or a code, usually issued to guests or fee-paying users. If you're free camping along a route and relying on council dump points, ring ahead to the relevant shire office if you're unsure. I've pulled into a rest area near Gundagai on the Hume and found a perfectly good dump point padlocked shut with no signage explaining why. Turned out it was seasonal maintenance. The Wikicamps comments saved us on the way back — someone had noted it was open again.

The actual process (so you don't make a mess)

I'll be straight: the first time I did this alone I held my breath the entire time and still managed to splash my shoes. It gets less fraught. The steps are pretty consistent regardless of what system your van runs.

For a cassette toilet: remove the cassette from the external service hatch (not from inside — your partner or kids do not need to see that). Carry it to the dump point. Open the pouring spout, not the fill cap. Tip slowly — slow is the word, not fast. Rinse the cassette at the tap (most good points have a dedicated rinse hose), replace the cap, return it to the van, then add a splash of chemical to the bowl once it's back in place. Wash your hands like you mean it.

For grey water tanks with a drain hose: connect the hose to the inlet on your van's grey tank, run it to the dump point opening, and open your grey tank valve. Keep the hose end submerged in the opening if you can — it stops splashback. Rinse when empty.

One thing I genuinely wish someone had told me earlier: always check the wind direction before you open anything. You'll thank me later.

Dump point etiquette — the unwritten rules that matter

Free camping communities can be pretty tight-knit, and dump point behaviour is something people notice. The basics:

• Leave the area cleaner than you found it. There is almost always a bin nearby — use it for your gloves, any used wipes, and any packaging from toilet chemicals.
• Don't queue and then take twenty minutes. If someone's waiting, move efficiently. Catch-up conversations with fellow travellers can happen literally anywhere else.
• Don't pour cooking grease, excess food scraps, or anything that isn't toilet or grey water down a dump point. These systems aren't designed for it and it causes blockages that then get blamed on caravanners generally.
• If the tap has a trigger nozzle, give the surrounding concrete a rinse before you leave.
• Report damage or blockages to the relevant council. Takes two minutes and keeps the facility open for everyone.

I'll be honest — the one that gets me is people who do a slow grey water dump, chatting on the phone the whole time, while three rigs are waiting. It's a small thing but it builds up.

Grey water rules: what you can and can't do at camp

This is where it gets a bit murky and varies by state. Our free camping rules by state guide covers the broad picture, but on grey water specifically: most states prohibit releasing grey water directly onto the ground at a campsite, including in national parks. Some states — particularly Western Australia and Queensland in certain zones — have stricter enforcement than others.

The practical upshot for families is this: if you're doing a lot of cooking and washing up (and we definitely are, because two kids), your grey water tank fills faster than you expect. We burn through roughly 15–20 litres a day just on dishes, handwashing and the dog's water bowl getting knocked over. On a 4-night free camp that's close to 80 litres, which is most of our grey tank. Plan a dump stop into your route every 3–4 days if you're off-grid.

Some people use a portable grey water tank on a trolley as overflow. I've seen this work well. I've also seen one tip over at a slope site. Secure it properly.

When a caravan park dump point is worth paying for

If you're mostly free camping — which we do probably half our nights these days — you'll pass plenty of caravan parks that offer a dump-and-dash for non-guests. Most will let you use their dump point, often for that $5–15 fee, and some will let you fill your fresh water tank at the same time for a few extra dollars.

We've done this at parks along the east coast run, and honestly it's a good system. You get a breather from setting up and packing down, the kids usually spot the jumping pillow and spend 45 minutes burning energy while I sort out the tanks, and we leave feeling reset. Sometimes the casual dump fee even comes off if you buy something from the camp store.

For places that really nail the dump point infrastructure — clean, well-signed, with a proper rinse hose and good lighting — the Inskip Point Recreation Area in Queensland is a good example of a well-run public facility. The Reflections Hawks Nest (Jimmys Beach) park in NSW also has solid amenities for both guests and passing tourers.

A word on keeping kids involved (sort of)

My kids now know the routine. They stay in the car, they don't touch anything, and whoever finishes their drink bottle fastest gets to press the tap trigger for the rinse. It's a small thing but it stops the "I'm bored" chorus and gets us out faster. Whatever works.

The other thing I've found useful: having a small kit in a zip-lock bag near the external hatch — two pairs of disposable gloves, a small bottle of hand sanitiser, and a folded bin bag. It's maybe 200 grams and I've been grateful for it at dump points with no bins and no tap in working order. Those exist. Be prepared.

Dump points aren't glamorous. But getting comfortable with them quickly is one of the things that unlocks proper free camping — the kind where you're not watching the tank gauge with anxiety every afternoon. Once it's part of the routine, it's just part of the routine.
