French Line vs QAA Line: Which Simpson Desert Route Should You Choose?

French Line or QAA Line? The better question is how each fits into your Simpson Desert crossing.

Both are legendary Simpson Desert tracks, but they aren't simply two competing routes between the same points. The French Line runs through the heart of the desert towards Poeppel Corner, while the QAA Line carries the crossing east between Poeppel Corner and Birdsville.

That means plenty of Simpson crossings involve both.

If you're planning the trip, here's what separates the French Line from the QAA Line, what conditions can make either one harder, and where Poeppel Corner and Big Red fit into the run.

French Line vs QAA Line: The Quick Comparison

French Line

  • Classic east-west Simpson Desert track
  • Long run through dune country
  • Known for repeated dune crossings and corrugations
  • Runs towards Poeppel Corner from the western side of the desert
  • A major part of the traditional Simpson crossing

QAA Line

  • Eastern Simpson Desert route
  • Links the Poeppel Corner side of the desert with Birdsville
  • Includes the run towards Big Red
  • Still crosses serious dune country
  • Commonly forms the eastern leg of a Simpson crossing

So if you're crossing the Simpson rather than exploring one section, this doesn't always come down to choosing one and skipping the other.

What Is the French Line?

The French Line is one of the best-known 4WD tracks in the Simpson Desert and a major part of the classic desert crossing.

It's the repetition that defines it. Dune after dune, long stretches of sand, corrugations and approaches that can become chopped up as the touring season progresses.

Conditions matter enormously. Sand temperature, wind, traffic, tyre pressures and recent weather can turn the same section of track into a very different drive from one trip to the next.

The French Line eventually brings travellers towards Poeppel Corner, where Queensland, South Australia and the Northern Territory meet.

What Is the QAA Line in the Simpson Desert?

The QAA Line is one of the major 4WD tracks across the eastern Simpson Desert, connecting the Poeppel Corner side of the desert with Birdsville.

For travellers crossing eastbound, the QAA Line usually follows the run through Poeppel Corner and carries the journey towards Big Red and Birdsville.

It still delivers proper Simpson dune driving. This isn't simply the easy road out once you've finished the French Line. Soft sand, chopped-up dune approaches and changing conditions can make sections demanding.

The QAA also puts you on the approach to the Simpson's most recognisable dune: Big Red.

For eastbound travellers, that makes the final section towards Birdsville a memorable finish to a long run across the desert.

French Line vs QAA Line: Which Is Harder?

There's no useful answer that ignores conditions.

The French Line has a reputation for being relentless because of the sheer repetition of dune crossings and the way heavily travelled approaches can deteriorate. The QAA Line can still be demanding, particularly when sand is soft and dune approaches are badly cut up.

Vehicle weight, tyre pressures, momentum and driver judgement can matter more than the name of the track you're on.

A heavily loaded rig running poor pressures can make either route harder than it needs to be.

French Line and QAA Line Track Conditions

Simpson Desert conditions don't stay fixed.

Wind can reshape dunes. Heavy traffic can chew up approaches. Hot sand can become noticeably softer later in the day, and weather can change access across the wider desert.

Before travelling, check current official park information, closures and access requirements rather than relying on a track report or video from months earlier.

Whatever the conditions, lowering tyre pressures appropriately and avoiding unnecessary wheelspin helps both the vehicle and the track.

Where Does Poeppel Corner Fit In?

Poeppel Corner is much more than another waypoint on the GPS.

It's the junction between major Simpson Desert routes and the point where Queensland, South Australia and the Northern Territory meet.

For travellers running the classic west-to-east crossing, it also marks the transition from the French Line side of the journey towards the QAA Line and Birdsville.

After days of dunes, reaching the corner is one of those moments that gives the crossing a sense of progress.

What About Big Red?

On the eastern side of the Simpson, Big Red is the landmark everyone knows.

Near Birdsville and connected with the QAA side of the crossing, it's the final big dune experience for many eastbound travellers.

Some rigs make the climb cleanly. Others need another run, different pressures or a different line.

Either way, the view from the top is a fitting way to finish the desert before rolling into Birdsville.

What 4WD Do You Need?

Both routes require a properly prepared 4WD and remote-area planning.

That means thinking beyond whether the vehicle has low range.

  • Suitable tyres in good condition
  • Tyre pressure gauge and air compressor
  • Rated recovery equipment
  • Sand flag
  • UHF communications
  • Offline navigation
  • Adequate fuel and water
  • Remote-area emergency planning

Weight matters in sand, so packing everything you own into the back of the rig isn't automatically good preparation.

Camping on a Simpson Desert Crossing

For plenty of travellers, the camps are as memorable as the driving.

Once the day's traffic disappears, you're left with dunes, open sky and a level of isolation that's difficult to find anywhere else.

Camp responsibly, follow current park requirements and leave the desert looking like you were never there.

So, French Line or QAA Line?

If you're asking which track offers the classic long run through the Simpson's dune country, the French Line is the obvious answer.

If you're asking about the eastern run towards Birdsville and Big Red, that's where the QAA Line comes in.

But for a traditional Simpson Desert crossing, the answer may simply be both.

French Line. Poeppel Corner. QAA Line. Big Red.

They're separate names on the map, but together they form some of the defining stages of a Simpson crossing.
