Plenty Highway — Stuart Highway to Boulia via Harts Range and Tobermorey
Red dirt and empty horizon, Alice to Boulia
The Plenty is the quiet cousin of the Tanami and the Birdsville, which is why you’ll often drive an hour without seeing a soul. It leaves the Stuart Highway north of Alice Springs and heads east past the Harts Range gem fields and the Atitjere community, then crosses open Mitchell grass plains and the Jervois and Tobermorey cattle stations before hitting the Queensland border and the Donohue Highway into Boulia. It is part sealed, part graded gravel, and the gravel surface is where trouble happens: bulldust holes, corrugations, sudden washouts, and road trains that own the middle. The Harts Range area is worth a detour for fossicking, and the night skies out near Tobermorey are the kind that make you quit your phone.
Rate it Moderate, mainly for distance and isolation. A high-clearance vehicle with quality all-terrain tyres, two spares, 40 litres of water per person and serious fuel range will do it. Fuel is sparse, so confirm what’s open before you leave Alice, and carry a satellite messenger because there is no cell service. Best season is May to September. After rain the road closes fast and stays slick; check the NT and Queensland road reports first. You can camp at roadside rest areas. What you get is a true crossing of the continent’s interior without the crowds. Have a dirty day.

Frequently asked questions
Can a stock SUV or 2WD handle the Plenty Highway?
In dry conditions, yes. A high-clearance 2WD or 4WD on all-terrain tyres is enough, since the difficulty comes from corrugations, bulldust and distance rather than technical obstacles. Carry two full-size spares, a puncture repair kit, a compressor and recovery gear, because a breakdown out here can mean a long wait.
Is the Plenty Highway open after rain?
Not reliably. Wet season rain (roughly November to April) can close sections for days, and the clay and black soil turns to slick mud that traps even 4WDs. The best window is May to September, but check the NT Road Report and QLDTraffic before you leave, and sit tight if it's closed.
Do I need a permit to drive the Plenty Highway?
No permit is needed to drive the public road itself. Stay on the formed road, because the land either side is pastoral lease or Aboriginal land. Don't camp or wander off without permission from the leaseholder, and observe any fire restrictions in force.
What's the roughest part of the trip?
Expect long stretches of heavy corrugations, patches of bulldust, cattle grids and floodway dips that can hold water or silt after rain. Road trains also run this route, so slow down and give them room when you see dust ahead. Sealed sections come and go, and the sudden change from bitumen to gravel catches people out.
How much fuel and comms do I need for the run?
Fuel stops are few and far apart, with long legs between Harts Range, Tobermorey and Boulia. Plan on carrying extra fuel beyond your normal range and confirm station and roadhouse hours before you go. There is no cell coverage along the route, so carry a satellite communicator or PLB and tell someone your timeline.
