AI-powered drone rescues lost hikers in record five hours

Two hikers experienced mild exposure effects but required no medical treatment and were safely rescued.
There's every chance we could have still been out there
The rescue commander reflecting on how the AI drone compressed what could have been a multi-day search into five hours.

Why does this matter beyond the obvious—that two people got found?

Mimi

Because it collapses time. A search that might have taken days now takes hours. That's not just convenience. That's the difference between mild exposure and hypothermia, between a rescue and a recovery.

Mark

The drone had a speaker. It could talk to them. That feels like a small detail but it's not, is it?

Mimi

No. It means the hikers knew help was coming. They weren't alone in the dark wondering if anyone was looking. The drone could tell them to stay put, to keep signaling. That changes everything psychologically.

Mark

Eberle mentioned dropping supply packages. That seems like the real future he's imagining.

Mimi

Right. He's thinking about overnight survival. If a drone can deliver a thermal blanket and water and food before dark, rescuers don't have to climb a mountain at night. The risk shifts from the rescue team to the technology.

Mark

But the technology has to find them first. How does thermal imaging work in practice?

Mimi

It sees heat. A human body radiates warmth. Against cold ground at night, that signature stands out. The red light from the phone helped too—gave the drone's camera something to lock onto.

Mark

This was the first time they'd used this system for an actual rescue. What does that tell you?

Mimi

That we're at the beginning of something. The technology existed, but it hadn't been tested in the field under real pressure. Now it has. And it worked. That changes how the agency thinks about what's possible.

  • Two hikers in their twenties vanished half a kilometre off-track in the dark and cold of Kosciuszko national park, invisible to conventional search methods.
  • A small red light from a mobile phone became their lifeline — the drone's thermal imaging locked onto their body heat against the frozen ground.
  • For the first time in a real rescue, the AI drone's speaker talked directly to the lost men while its spotlight guided ground teams to the exact location.
  • The entire operation closed in under five hours — a search that could have stretched across days was over before morning.
  • Commanders immediately saw the wider stakes: faster rescues mean fewer volunteers exposed to dangerous overnight conditions on the mountain.

On a Tuesday evening in the Australian alpine backcountry, two young men disappeared into the dark of Kosciuszko national park — and were found again within five hours, not by the slow sweep of human searchers, but by a machine that sees in heat. Fire and Rescue NSW deployed an AI-powered drone for the first time in a live rescue, compressing what might have been days of searching into a single night. It is a quiet milestone in the long story of how human ingenuity reaches back for those who are lost.

Two men in their twenties left the Dead Horse Gap track in Kosciuszko national park on a Tuesday evening and did not return. When they failed to appear by 7pm, Fire and Rescue NSW launched what would become a landmark operation — deploying an AI-powered drone fitted with thermal imaging and a real-time speaker system into the alpine dark.

The hikers had drifted half a kilometre off the marked route. Conventional search methods would have struggled to find them in those conditions, but the men had one small tool: a mobile phone with a red light function, which they aimed skyward. The drone's thermal sensors caught their body heat against the cold ground, and from there the operation moved with a speed that would have been unthinkable before.

Operators spoke to the hikers directly through the drone's speaker, while its spotlight guided ground teams to the precise location. From the moment the alarm was raised to the moment both men were safe, less than five hours passed. They had mild exposure effects but needed no medical treatment.

Inspector Phillip Eberle, the regional duty commander, was candid about what the technology had changed. A search like this could easily have run for days. Instead, it ended in a single night — and with less risk to the volunteers who would otherwise have spent hours on the mountain in difficult conditions.

Eberle's vision reaches further still. He foresees drones that don't just locate stranded people but drop emergency supply packs to them, allowing rescuers to wait for safer daylight conditions rather than pressing into dangerous terrain overnight. Commander John Marzol added a practical note: hikers heading into the snowfields should still register with the National Parks and Wildlife Service and carry a free Personal Locator Beacon. The technology is powerful, but it works best when it isn't searching blind.

Two men in their twenties stepped off the walking trail in Kosciuszko national park on a Tuesday evening and did not come back. By 7pm, when they failed to appear at the rendezvous point, the alarm went up. Fire and Rescue NSW mobilized what would become a turning point in how the agency finds people lost in the backcountry: a drone equipped with artificial intelligence, thermal imaging, and a speaker system that could talk to the missing hikers in real time.

The men had been walking the Dead Horse Gap track, roughly 35 kilometres southwest of Jindabyne, when they wandered half a kilometre off the marked route. In the dark and cold, they were effectively invisible to conventional search methods. But they had one advantage: a mobile phone with a red light function. As the drone lifted into the night sky, the hikers used that small beam to signal upward, a human-made lighthouse in the dark. The drone's thermal imaging picked up their body heat against the cold ground.

What happened next was seamless in a way that would have been impossible just months earlier. The drone's built-in speaker allowed operators to communicate directly with the lost hikers. Its spotlight then guided ground rescue teams to the exact location. The entire operation, from the moment the men were reported missing to the moment they were found and brought to safety, took less than five hours. Both men were suffering only mild effects of exposure. They declined medical treatment.

Phillip Eberle, the Fire and Rescue inspector and regional duty commander for the NSW Alpine area, understood immediately what had just happened. He told the ABC that this technology had compressed what could easily have become a multi-day search into a single night operation. "There's every chance in the world we could have still been out there," he said. The drone's AI detection system had never been used for a rescue mission before. This was the first.

The implications rippled outward quickly. Eberle noted that faster rescues meant not just better outcomes for lost hikers, but reduced risk for the volunteers doing the searching. Fewer hours on the mountain in difficult conditions meant fewer opportunities for rescuers themselves to become casualties. "It means less time on the mountain and less time looking for people, and reduced risk so that the volunteers can get home to their families quicker," he said.

But the technology is still in its early stages, and Eberle's vision extends further. He imagines a future where drones do not simply locate stranded people but also deliver to them. Emergency supply packages dropped from the sky could keep someone warm and fed through the night, eliminating the need to send rescue teams into dangerous terrain in darkness. "We can save putting rescuers at risk overnight and drop a rescue pack to people so they're OK overnight, and be there first thing in the morning when it's safer for everyone," he told the ABC.

John Marzol, the Fire and Rescue commander, used the incident to reinforce a practical message: hikers heading into the snowfields should notify the National Parks and Wildlife Service before they go, and should register for free Personal Locator Beacons. Technology like the AI drone is powerful, but it works best when it does not have to search blind. The two men in their twenties walked out of Kosciuszko national park alive and largely unharmed, their names unrecorded in the reporting, their story now a data point in the growing case for what machines can do when humans are lost.

It's definitely helped make what could have been a long-term incident into a very short-term incident.
