Are you planning to undertake the iconic Simpson Desert Crossing? Deep in the heart of Australia lies one of the world’s largest and most remote deserts, defined by longitudinal dunes. The Simpson Desert Crossing is for those drawn to adventure, personal challenge and the remote beauty of central Australia. This guide will help equip travellers for an unforgettable experience across Australia’s iconic Simpson Desert Parks…

You may think of a desert as lifeless, arid, and waterless. Think again. The desert is home to diverse wildlife, including varied bird species and marsupials like the Plains Mouse, dingos, and camels. Dunes are dotted with spinifex, acacia shrubs, grevillea, sandhill wattle, and Mulga trees. Discover springs, salt pans, and sand dunes, making the Simpson Desert a diverse and exciting habitat.

TRAVEL TIP: The best time to explore the Simpson Desert Parks is Spring, from August to October. Experience an array of lively colours as the desert foliage bursts into flowers!

As beautiful as discovering the Desert Parks region is, the remote, harsh, and extreme landscape requires careful planning, preparation, and a reasonable degree of off-road driving capability. Please take a look at our article on how to drive in sand.

Essential Checklist for Munga-Thirri-Simpson Desert Crossing: 

The Desert Pass provides an information handbook and three maps covering three sections of the Desert Parks. It also allows entry to camping in the eight National Parks and Reserves. A sand flag is also mandatory for your vehicle on the Simpson Desert Crossing.

TRAVEL TIP: The most direct route to Birdsville is via the French Line to Poeppel Corner; from there, the K1 runs 8 km to the QAA line, which continues to Big Red and Birdsville. The distance from Dalhousie Springs to Birdsville is 430 km.

IMPORTANT: DROP YOUR VEHICLE’S TYRE PRESSURE FOR INCREASED TRACTION AND PRESERVE THE DESERT TRACKS

Tips for Driving in Sand Dunes on the Simpson Desert Crossing

Experience driving a 4×4 vehicle in the sand is recommended due to the remote nature of the Desert Parks. If you’re planning a journey to the desert, you can see our guide on how to drive in sand here.

Guide to 4×4 Modifications

While having some aftermarket modifications to your 4×4 will assist in this epic journey, also ensure a comprehensive vehicle service is carried out before the departure.

1 – High Clearance 4×4: A 4×4 vehicle with high clearance is essential for crossing steep sand dunes and the deep sandy tracks.

2 – Low Range Gearing: Low 4×4 (low 4) geaing is also essential for the challenging terrain.

3 – Upgraded Suspension: Enhancing your 4×4’s suspension with aftermarket heavy-duty suspension and shock absorbers can improve the load-carrying capacity. Additionally, this will enhance vehicle stability and comfort.

4 – Tyres and Air Compressor: Dedicated off-road tyres can help enhance traction, while using tyre deflators and an air compressor will allow you to adjust tyre pressures as required.

5 – Dual Battery System: A dual battery system ensures accessories like lights, fridges, and electronic devices are keep operating without drawing from the main vehicle battery.

6 – UHF Radio: A UHF radio is essential for communicating with oncoming vehicles. Visibility looking ahead is very limited, so announcing your location can reduce the risk of collisions, as well as the crucial use of the Sand Flag.

7 – Fuel Capacity: A long-range fuel tank will allow peace of mind between refuelling points that are 500 km apart. Otherwise, the ability to carry a jerry can with additional fuel will assist with fuel usage.

8 – Recovery Gear: Carry essential recovery items, such as a shovel, recovery tracks (like MAXTRAX), a snatch strap, and rated recovery points.

Guide to The Simpson Desert Crossing: Dalhousie Springs to Birdsville

Day 1: Depart Dalhousie Springs Campground and begin the desert crossing on the French Line, including the Simpson Desert Regional Reserve and Simpson Desert Conservation Park. This is a day of sandy track driving over small sand dunes. There are no designated campgrounds, so watch for a spot to camp for the night. Enjoy the isolation of the remote desert as the sun lowers over the dunes, the night sky revealing its beauty of stars.

Day 2: Start the day with a vehicle checkover. Continue along the French Line, the dunes increasing in size. As you progress, pronounce your location on your radio as you pass track markers. This is a safety precaution for oncoming traffic, as visibility between the dunes is poor. By afternoon, you should reach the salt lakes and look for a camp amongst the Mulga Trees.

Day 3: Continue the journey along the French Line as you close in on the iconic landmark Poeppel Corner. (This border landmark is for SA, QLD, and NT.) Take the K1 track to the QAA line. By afternoon, Big Red will be spotted in the distance! Try driving up the massive dune, taking in views from the top. Continue 38 km to Birdsville Tourist Park.

Reaching the iconic ‘Big Red’ sand dune gives a great sense of achievement and marks the end of the Simpson Desert Crossing after days of remote sand driving. Why not celebrate this achievement with a meal at the Birdsville Pub? What an adventure! The Simpson Desert Crossing is now ticked off the bucket list! 

Looking After Our Desert Parks, and the Simpson Desert

• Note: The dune tracks are rutted and worn beneath the sand due to people driving with tyre pressures that are too high. Please lower the tyre pressure and take care of the tracks. See our guide to driving in sand here.
• Take your rubbish with you, including toilet paper!
• Please ensure that you bury your toilet waste at least 15 cm deep and 100 m from a waterway, or carry a camp toilet.
• Extinguish fires (though fires are not permitted in the Desert Parks).
• Leave no trace to keep these places pristine for future generations to experience.
