Australia’s fire season looms and researchers are looking to move beyond ‘detecting fires with people in towers and binoculars’.

SYDNEY—In October, a sensor mounted on an 8.5-metre pole in the Australian countryside detected small particles in the air near a timber plantation and sent out an alert.
When plantation staff arrived, they found a small man-made fire that was already under control, but the incident offered a glimpse of how authorities hope to use new technology to battle bushfires that have grown increasingly intense in recent years.
As a new fire season begins in Australia—a recent bushfire ravaged about half of Fraser Island in the country’s east—researchers are looking to rely more on technology to find blazes quickly and better predict their path.
A monthslong government inquiry into the devastating 2019-2020 fire season in Australia, which killed more than two dozen people and burned an area bigger than Washington state, concluded that authorities need to be better prepared and recommended that officials work with the private sector to develop new technology.
“We’re still detecting fires with people in towers and binoculars. We’ve got to move beyond that,” said Leigh Kelson, program director at FireTech Connect in Australia, a government-funded effort to help startups develop new firefighting technologies. Firefighters also rely on the equivalent of 911 calls to find new blazes.
The ideas researchers are exploring include fitting drones with lasers that can map dry areas at higher fire risk and whether satellites can detect extreme fire behaviour.
Last fire season, authorities were surprised by how quickly the blazes spread and how long they burned, which they later attributed to a prolonged drought that had left the land parched with plenty of dry vegetation to fuel the flames. Last year was Australia’s hottest year on record, according to the government’s Bureau of Meteorology, and fires are projected to become more intense and frequent because of climate change.
Parts of Australia have received more rainfall in recent months, and the current fire season isn’t expected to be as severe. Still, firefighters have struggled to control some of the blazes. The fire on Fraser Island, the largest sand island in the world and a Unesco World Heritage site, prompted officials to tell some residents to evacuate from homes in the path of the flames. On Sunday, firefighters said rainfall had finally helped to contain that blaze, which started in mid-October.
Other regions, including the western U.S. and even in frosty Siberia, have experienced particularly intense fire seasons recently, stretching global firefighting resources and making early detection of fires more crucial. Fires left unchecked can create their own weather systems, raining embers down on nearby communities and pushing dangerous smoke into big cities and even to neighbouring countries.
The sensor that picked up the October fire near the timber plantation is one of more than 40 in a network that covers an area nearly double the size of New York City in Australia’s Victoria state. The solar-powered, cylinder-shaped sensors are packed with instruments including optical and thermal cameras, flame detectors, particle counters for air quality, and ground-vibration readers. The data are publicly available online in real-time.
Attentis Pty. Ltd., a Melbourne, Australia-based company, finished installing the network in early 2019 as a pilot project to demonstrate the technology. They didn’t get much use detecting fires last season because the blazes were too far away.
Cameron McKenna, managing director at the company, said he is in talks to install similar sensor networks to improve fire detection capabilities in other parts of the country. “We use multiple methods of detection as opposed to a single method,” he said.
In Canberra, Australia’s capital, researchers are working with a local firefighting agency to install video cameras on four fire towers. One tower will also have a thermal camera installed.
A computer program will scan images from the thermal camera to detect fires, and a person will monitor the other video feeds. Researchers plan to develop a computer program to automatically scan the video feeds too, said Marta Yebra, director of the Australian National University Bushfire Initiative. The idea is to determine whether the cameras detect new fires quicker than the old-fashioned way of having a person in the fire tower, she said.
Rohan Scott, who leads the rural fire service in the Canberra area, said people in towers on average spot fires within seven minutes of ignition. But the towers are only staffed on high-risk days.
“If we can get detection 24/7 but at the same speed as a human-manned fire tower, then I think that would be a good outcome,” he said. “Anything quicker than that would be a definite bonus.”
Other ideas involve using drones fitted with lasers to create detailed maps so authorities know which areas have more dry vegetation and present a higher fire risk. One recent effort involved researchers poring over satellite imagery in an attempt to build a model for detecting extreme fire behaviour from orbit. They found that changes in smoke colours could help predict fire behaviour, according to the Minderoo Foundation, a nonprofit that sponsored the research.
One company, Fireball.International Pty. Ltd., says its machine-learning method can detect smoke from ground-based cameras and fires from heat signatures on thermal-satellite images. Its system is already being used by a big power company in California, and Fireball plans to begin pilot programs in Australia this fire season, executives said.
A prototype of the system detected smoke from fires within 15 minutes of ignition, while averaging less than one false positive a day per camera, according to an analysis published in a peer-reviewed journal in January. It said there is room for improvement.
“People are beginning to realise, ‘Gosh, we really can detect a fire in the first five minutes,’” said Tim Ball, an academic and co-founder of the company who is also a former firefighter.

Australian football superstar and Matildas captain Sam Kerr has joined one of the world’s most exclusive luxury watch brands, reflecting on the sacrifices behind a career at the pinnacle of professional sport and revealing she only signed with her new club last week.
As Richard Mille’s first and only Australian partner, Kerr has joined an elite group of global athletes, artists and innovators associated with one of the world’s most prestigious watchmakers.
Speaking in Sydney, the 32-year-old reflected on her next chapter, the extraordinary growth of women’s football and the personal sacrifices required to reach the top of the game.
Founded in 2001, Richard Mille has built a reputation for producing some of the world’s most technically advanced and exclusive timepieces. The Swiss watchmaker is renowned for its use of ultra-lightweight materials, Formula One-inspired engineering and limited-production watches that often sell for hundreds of thousands of dollars and, in some cases, more than $1 million.
Its ambassadors include tennis great Rafael Nadal, Formula One stars Charles Leclerc and Lando Norris, actress Michelle Yeoh and sprint champion Shelly-Ann Fraser-Pryce.
During the Sydney event, Kerr wore the Richard Mille RM 07-04 Automatic Sport, a lightweight model featuring a pink case, blue strap and skeletonised movement. Designed for active lifestyles, the watch reflects the brand’s philosophy of combining high-performance engineering with luxury craftsmanship.
For Kerr, becoming the brand’s first Australian partner is a source of considerable pride.
“Of course, being the only Australian is incredible to me,” she said. “I am very proud to be Australian and I like to put Australia on the map.”
The announcement comes as Kerr prepares for the next stage of her football career following her departure from Chelsea after six-and-a-half years.
While speculation around her future has been mounting for months, Kerr revealed a decision was only finalised recently.
“Everyone thinks that it was decided and I’ve known that (it was) reported that I’d signed somewhere in April, but honestly, I only signed my contract on Wednesday last week,” she said.
“I really hadn’t decided what I was going to do until last week.”
Kerr said she expects details of her new club to be announced around the beginning of July once her Chelsea contract officially concludes.
Despite her excitement about what lies ahead, she admitted leaving one of the world’s biggest football clubs has been emotional.
“I am really sad about it,” she said. “It’s been my home for 6.5 years. I have so many good memories there. I have so many amazing teammates. I’m sad to leave.
“It sucks to leave such a big club like Chelsea too, but it comes to an end to everything, right?”
The 32-year-old also reflected on the transformation of women’s football during her career, describing the Matildas’ rise from relative obscurity to household-name status as one of her proudest achievements.
“What the Matildas have done over the last four or five years has been incredible,” she said.
“The most important thing for me is that you leave the game in a better place.”
Kerr noted that when she began playing, there were few professional pathways for women, limited sponsorship opportunities and crowds that bore little resemblance to those regularly attending matches today.
“We are a part of that generation that still knows what it was like when there was no one in the crowd,” she said.
Today, she said, crowds of tens of thousands remain something the team never takes for granted.
“Even last night we had 20,000 on a Tuesday night nearly. That’s special to us,” she said.
“We feel very lucky that people come out and spend their money and come to a game and watch us.”
Yet behind the accolades, sponsorships and sold-out stadiums, Kerr said there have been significant personal sacrifices.
“I’ve been living out of home since I was 17 years old. I’ve missed a lot of my family’s life,” she said.
“I’ve missed a lot of weddings. I’ve missed funerals. I’ve missed so many things that people don’t see.”
Kerr revealed she was unable to return home for her grandmother’s funeral last year because of football commitments.
“You have to love what you’re doing. You have to want to sacrifice,” she said.
“Everyone makes sacrifices, of course, and what I do is a massive privilege, but there comes a lot of sacrifice with it.”
Away from football, Kerr said Australia remains central to her identity despite spending much of her adult life overseas.
“I think we take for granted in Australia the beaches, the ocean, the open spaces,” she said.
As she prepares for a new club, a new season and a new role with Richard Mille, Kerr said she remains motivated by the same passion that first drew her to the game as a teenager.
“It was really organic,” she said of her relationship with the luxury watchmaker.
“It’s a real family brand.”
