Reading a dump point before you use it: the checks most tourers skip

There's a dump point out the back of the Birdsville pub yard that half the grey nomad grapevine will tell you about like it's a state secret. It isn't. It's on the CamperMate app, it's on the council's own list, and it works exactly the way it's meant to. But I've stood behind blokes at that same point, and at a dozen others, watching them do it wrong in ways that eventually get these facilities locked, fenced off or removed altogether. Denise reckons I've become insufferable on the subject. She's probably right.

Here's the thing nobody tells you when you buy your first van with a cassette toilet or a black tank: the dump point itself isn't the hard part. Reading it before you commit is.

What a dump point actually is (and isn't)

A dump point is a fixed, council or shire-provided disposal point tied into the sewer or a septic system, built specifically to take caravan and motorhome waste. It is not a stormwater drain, not a long-drop, not the bush toilet pit some free camp has dug for tent campers, and it is definitely not the grate outside the servo toilets. I've seen all three used as substitutes by people who should know better, usually because the real dump point was a five-minute drive further on and they couldn't be bothered.

Most states now publish official lists. Queensland's regional councils maintain them on their own websites, and NSW has a decent register through the Dump Point locator that most park associations link to. The point is these are engineered facilities — pumped or gravity-fed into sewer, sometimes with a flush-down bowl, sometimes just a grated pit — and they're built to a load and volume the system can handle. Chuck the wrong thing down one and you're not just being a nuisance, you're potentially blocking infrastructure the whole town relies on.

The five-second check before you back in

I do the same walk-around every single time, and it takes less time than backing the van into position.

First, is there actually water pressure at the tap, and is the hose provided (if there is one) clean and separate from anything used for drinking water fill? Some dump points share a tap area with a potable water point, and I've seen tourers rinse their cassette right next to where the next bloke fills his tank five minutes later. If there's any doubt, I don't use the site tap for a cassette rinse at all — I carry my own dedicated rinse hose, kept in a bag well away from the drinking water gear.

Second, look at the grate or bowl itself before you commit anything. If it's already backed up, blocked with wipes or clearly not draining, that's not your dump point for today — report it if you can, and find the next one. I've turned around twice in the last three years because a facility looked half-broken, and both times it turned out someone upstream had put things down it that don't belong there.

Third, check for signage about grey water. Some dump points take grey and black together, some are black only and expect you to release grey water on the ground where permitted (check the local rules, because plenty of places don't permit it at all), and a few request you don't tip grey into the fitting because of the volume. It sounds fussy, but it's the difference between a facility that stays open and one that gets a council notice slapped on it within a year.

The stuff that actually blocks these systems

Dusty would tell you this from the mechanical end and I'll tell you from the "I've queued behind the bloke who did it" end — wet wipes are the single biggest killer of dump point infrastructure in this country, and it's not close. They don't break down like toilet paper does, they don't matter if the packet says "flushable," and they catch on every valve and elbow in the line. Sydney Water and most other utilities have been running public campaigns on exactly this problem for years because it costs ratepayers real money to clear blockages caused by wipes, nappies and sanitary products going down systems they were never designed for.

If you use wipes in the van (plenty of people do, fair enough), bag them and bin them. Don't put them down the cassette, don't put them down the dump point. Same goes for nappies, which I still see occasionally at free camp dump points, usually double-bagged and shoved in badly, occasionally not bagged at all.

Chemical toilet treatments are a separate conversation. The older formaldehyde-based ones are being phased out in a lot of jurisdictions and some council facilities specifically ask you not to use them because they interfere with the septic or treatment process on the other end. The enzyme and bio-based treatments are far more widely accepted now. If you're still running the old blue stuff, it's worth checking whether your destination even accepts it before you head off — some remote community and national park dump points have signage saying they don't.

State by state, the rules aren't identical

This is where I see people catch themselves out, because they assume what worked in Queensland works the same in Western Australia. It mostly does, but not always.

In WA, a lot of the more remote dump points are shire-run and genuinely basic — a pit, a tap, sometimes no bin at all, so you carry your rubbish out. Along the Gibb River Road corridor and down through the Kimberley more broadly, treat every dump point as though it might be the last reliable one for a couple of hundred kilometres, and don't assume the next roadhouse has one just because it's got fuel and a counter meal.

South Australia's outback tracks are similar. Along the Oodnadatta Track and the Birdsville Track, dump points cluster at the townships — Marree, William Creek, Oodnadatta, Birdsville itself — and there's genuinely nothing reliable between them. Plan your black tank capacity around the distance between towns, not around how full the tank feels when you leave.

Victoria and NSW tend to have denser networks because there are simply more towns closer together, but that density brings its own trap: because there's always another one twenty minutes up the road, people get lazy about checking the current one is actually working before they use it.

Free camps without a dump point at all

This is the bit that actually matters more for etiquette than the engineered dump points do, because a badly-run engineered facility gets a council works order. A badly-run free camp with no facilities at all just gets closed, full stop, no review, no appeal.

If you're cassette-only and free camping somewhere with no dump point for a stretch — plenty of the sites along the Birdsville Track or out on the Oodnadatta Track fall into this category — you carry it until you find one. That's the whole rule. I know grey nomads who've fitted a second cassette specifically for this reason, and it's not a bad call if you're the type who does long stretches between towns.

Our own piece on bush toilets and grey water etiquette covers the digging-your-own-hole side of things in more detail than I've got room for here, but the short version is: it's not your job to improvise a dump point out of a free camp's dirt, no matter how tempting it looks after four days without one.

My honestly contrarian bit

I'll cop some flak for this, but I reckon the "flushable" wipes industry has done more damage to free camping access in this country than any single group of inconsiderate campers. Councils that would otherwise leave a dump point open and unsupervised are increasingly locking them, gating them, or removing them entirely because the maintenance bill from blocked systems gets too high to justify a facility that a small percentage of users keep wrecking. Every time a shire pulls a dump point off the list, that's one fewer stop for everyone, and it's very rarely the free campers who get blamed publicly, even though the wipes packet clearly wasn't biodegradable.

The five-minute habit that keeps these places open

Before I pull away from any dump point, I do a last look: is the area cleaner than I found it, did I use my own hose and not the shared one for a cassette rinse, is the bin (if there is one) not overflowing with things I've added to it, and did I actually flush the fitting down properly rather than just walking off. That last one sounds obvious, but I've watched people drive off with the bowl still half full because they didn't want to wait the extra thirty seconds for the flush cycle.

None of this is hard. It's the same discipline as the hitch-up checklist we've written about before — a short, boring routine that only matters when someone skips it. Do it every time and these places stay open for the next couple through, whoever they are.
