Kellys Camp to Cunnamulla — Bulloo Overflow Channel Track via the Hungerford Dingo Fence
Dingo Fence, clay pans, and nothing else.
The Bulloo Overflow country in far southwest Queensland doesn’t care about you. This track runs from Kellys Camp south of Thargomindah northeast toward Cunnamulla, crossing the seasonally flooded Bulloo Overflow channels — a braided tangle of gibber plains, box tree woodlands, and clay pans that turn to axle-deep mud the moment the sky opens. The historic Dog Fence at Hungerford, the longest fence in the world at over 5,600 km, bisects this country — a physical reminder of how seriously Australians once took the dingo problem. Fuel at Thargomindah before you leave. There is nothing else.
This is genuine remote outback travel — no technical rock, but claypan mud and unbridged crossings in wet conditions can stop a vehicle dead. High-clearance 4WD with recovery gear, two spare tyres, and a minimum 300 km fuel range is required. Cell service is zero. Royal Flying Doctor Service covers the region. Best run May through September in the dry season — attempting this after rain is a gamble that costs people days. Satellite communicator is non-negotiable. What you get out of it is genuine emptiness, stars so thick they blur, and that particular Queensland outback silence that costs nothing and means everything.

Frequently asked questions
Can a stock Prado or 4Runner handle this, or do I need a lifted rig?
A stock high-clearance 4WD will manage in dry conditions, but the clay pan sections and Bulloo Overflow channels can get soft and rutted fast. Mud terrain tyres, a snatch strap, and a MaxTrax minimum — a lift helps but isn't the deciding factor. Underbody armour is worth having if you're running anything low.
What happens to this track after rain?
Clay pans turn to axle-deep bog with almost no warning, and the Bulloo Overflow channels can become impassable for days or weeks after significant rainfall. This route is strictly a dry-season run — May through September. Check with Thargomindah locals or the station leaseholders before you roll if there's been recent weather.
Do I need a permit to drive through here?
Sections of this track cross private station leases, so you'll need to contact the relevant landholders before entry — no permit system exists but access is at the landowner's discretion. The Dingo Fence section near Hungerford sits on managed land; respect closures and leave gates exactly as you find them.
What's the hardest section on this track and what should I expect?
The Bulloo Overflow flood channel crossings are where rigs get stuck — soft, undermined banks and clay bases that look solid until they aren't. Approach every crossing on foot first, pick your line, and don't follow another vehicle's tracks blindly; they may have been laid when conditions were totally different.
How do I sort water and fuel across 300km with no services?
Thargomindah is your last guaranteed fuel before you commit — there is nothing between the start and Cunnamulla, roughly 300km. Carry a minimum 50 litres of spare fuel and at least 20 litres of drinking water per person; there are no reliable water sources on route and zero emergency services cell coverage the entire way.
