In the summer of 2013, the Thompson family — David, Sarah, and their two young children — sold their comfortable home in Perth, Western Australia, packed up their belongings into a gleaming white caravan, and set out on what they called “the adventure of a lifetime.”
They promised friends and family they’d be gone for about a year — a full circuit around Australia, exploring the beaches, deserts, and outback towns that make up the heart of the continent.
But that year came and went. Then another. And another.
No one ever saw the Thompsons again.
THE BEGINNING OF THE DREAM
David Thompson, 38, was a project manager for a mining company. His wife, Sarah, 34, was a teacher who loved nature and photography. Together, they shared a dream: to take their children — Emma, 7, and Jack, 5 — on a cross-country trip before the kids grew too old for such an adventure.
The family held a farewell barbecue on a sunny Saturday afternoon in March 2013. Friends remember laughter, music, and excitement in the air. David toasted to “a year of freedom,” and Sarah promised to send postcards from every major stop.
The next morning, they hit the road, heading north. That was the last confirmed sighting of them.
THE FIRST SIGNS OF SILENCE
At first, no one worried. The Thompsons had mentioned wanting to disconnect from technology — “no phones, no email, no stress,” Sarah wrote in her last Facebook post.
But as weeks turned into months, the silence grew unsettling. They missed birthdays, calls, holidays. By Christmas, when even their elderly parents received no word, concern turned to panic.
In January 2014, Sarah’s sister, Claire Matthews, filed a missing persons report with Western Australia Police.
“They loved their family,” Claire told reporters. “There’s no way they’d just disappear without saying a word.”
THE INVESTIGATION BEGINS
Police began tracking the family’s known route — but from the start, the case was a labyrinth.
Bank records showed their last known transaction: a fuel purchase at a small roadhouse in Carnarvon, a coastal town nearly 900 kilometers north of Perth. Witnesses remembered the family stopping for snacks and chatting about heading inland toward the Kennedy Ranges.
That was April 2, 2013.
After that, nothing.
No further card activity.
No phone pings.
No sightings.
Their caravan, truck, and belongings simply vanished into the vast Australian outback — one of the most unforgiving and sparsely populated regions on Earth.
THE DESERT SEARCH
Over the next two years, police conducted multiple search operations covering thousands of square kilometers. Helicopters scanned the desert for signs of wreckage or campfires. Volunteers on ATVs combed dry riverbeds and abandoned tracks.
Nothing surfaced. Not even tire marks.
“It’s like they were swallowed by the land,” one investigator said.
Theories emerged:
- An accident: perhaps they drove off a cliff or into an unmarked mine shaft.
- Exposure: trapped by flash floods or dehydration.
- Foul play: someone might have taken advantage of their isolation.
But there was no evidence for any of it.
ELEVEN YEARS OF HEARTACHE
By 2016, the case had gone cold. The Thompsons’ parents, both in their seventies, still set a place for the family at Christmas dinner each year.
Family games
“We can’t move on,” Sarah’s father said in a television interview. “There’s no closure without knowing.”
In 2018, a documentary crew revisited the story for the program “Missing Down Under.” The team retraced the family’s supposed route and interviewed locals.
One farmer from Gascoyne Junction claimed he’d seen a caravan matching the description “driving off the main road toward the hills” in early April 2013 — but he couldn’t recall the exact day. That clue, too, went nowhere.
The police case file thickened with hundreds of pages, leads, and dead ends.
THE STRANGE DISCOVERY
In late 2022, a bush pilot named Michael Dean spotted something glinting in the desert during a routine flight between Meekatharra and Mount Augustus. Investigators were dispatched to the coordinates — and for the first time in nearly a decade, there was a breakthrough.
Half-buried in red dust lay the rusted remains of a Land Cruiser chassis.
The vehicle’s VIN number confirmed it belonged to David Thompson.
Nearby, searchers found fragments of metal and what appeared to be part of the caravan’s frame. But inside — no bodies, no personal items, no clues. The desert had taken everything.
A NEW THEORY EMERGES
Forensic experts determined the car hadn’t crashed. Instead, it seemed to have been abandoned deliberately.
Car dealership
That revelation changed everything.
Detective Inspector Hugh Parsons, who now leads the case, explained:
“There’s no sign of an accident. The Thompsons might have walked away from the vehicle — or from their lives.”
Investigators reexamined financial records and noticed something strange: a withdrawal of $50,000 in cash two weeks before their disappearance.
Why would a family planning a trip across Australia suddenly withdraw that much money?
And where did it go?
A FAMILY SECRET
In 2023, new information surfaced from one of David’s former coworkers. He claimed David had been “under immense pressure” at work before quitting. There were rumors of a financial dispute with his employer, and whispers that he’d been “considering disappearing” to start over.
Others dismissed that theory, insisting the Thompsons were devoted parents who would never endanger their children.
Sarah’s sister responded angrily to speculation:
“David was stressed, yes. But Sarah loved her kids more than anything. They wouldn’t just vanish on purpose. Something happened to them out there.”
THE MYSTERY DEEPENS
Eleven years on, the disappearance of the Thompson family remains one of Australia’s most haunting mysteries.
Their case has sparked podcasts, documentaries, and online sleuth communities determined to solve it. Thousands of people have analyzed satellite images, mapped possible routes, and shared theories ranging from tragic accidents to secret new identities abroad.
Some claim the family might have perished in the Kennedy Range National Park, their remains lost to time and wildlife. Others believe they could have fled to another country under assumed names — escaping debt or danger.
The truth, for now, lies buried somewhere between the two.
A FINAL MESSAGE
Each year, on the anniversary of their disappearance, family and friends gather at the Perth foreshore, releasing lanterns into the night sky.
Each lantern bears a name: David. Sarah. Emma. Jack.
“We don’t know if they’re gone or alive somewhere,” Sarah’s mother said quietly at this year’s vigil. “But wherever they are, I hope they’re together.”
The flickering lights rise into the dark — tiny symbols of hope against the endless expanse of mystery that still surrounds the Thompsons.
