Outback pastoralists use drones and helicopters to manage livestock stranded by record floods

They're all fine. Just living the dream out there at the moment.
Sharon Oldfield describes her 4,000 cattle stranded for four months on an island created by record floodwaters.

In the remote outback of South Australia, where water is ordinarily the measure of survival, an excess of it has redrawn the terms of that same survival. Since February 2026, record floodwaters have isolated thousands of cattle and sheep across stations like Cowarie and Quondong, forcing pastoralists to reach their animals by helicopter and thermal drone rather than by road. The land that once demanded endurance against drought now demands ingenuity against inundation — and in a quiet irony, the livestock are thriving, the tanks are full, and the ancient red country has turned, improbably, green.

  • Around 4,000 cattle at Cowarie Station have been cut off since February, with floodwaters fed by successive pulses from Queensland rivers showing no sign of retreating before September.
  • At Quondong Station, 147,710 hectares of partially submerged land made traditional mustering impossible, forcing the station to bring in specialist thermal drone operators to locate scattered sheep herds.
  • Merino wool acts as thermal insulation, making the sheep nearly invisible to drone cameras — a single paddock can take a full day to survey, and broken fences mean located mobs may have moved by the following morning.
  • A decision to shear in 50-degree January heat, questioned at the time, proved to be the margin between survival and catastrophe — sheep with a full fleece would not have survived the floods that arrived weeks later.
  • Despite the isolation and logistical complexity, both stations report livestock in good condition, water tanks full, and a landscape so transformed by rain that pastoralists are describing their outback properties as 'English green.'

Four months after floodwaters cut Cowarie Station in two, Sharon Oldfield still cannot reach half her property by road. Around 4,000 cattle remain on the far side of a water-filled channel, 250 kilometres north of Marree in outback South Australia, and no road access is expected until September. The water arrived in waves — local rain, then floodwaters rolling down from Queensland through the Diamantina and Georgina rivers, then more rain — each pulse keeping the channel full. Oldfield checks on her cattle by helicopter. They appear, she says, entirely unbothered. A neighbouring station has taken the longer route, walking cattle over 100 kilometres around the floodwaters to reach a transport point.

At Quondong Station to the east, the challenge is scale. Across nearly 148,000 hectares of partially submerged land, locating thousands of sheep on foot was never a realistic option. The station brought in Tony Eldridge and Colleen O'Callaghan, a couple who moved from careers in dentistry and military work into a travelling drone security business, and who had already been using thermal imaging to assess flood damage across the region. Their task at Quondong is methodical and slow: mapping impassable areas, estimating when tracks might dry, checking fence lines, and systematically crisscrossing paddocks to count stock.

The work is complicated by the sheep themselves. Merino wool insulates so effectively that the animals barely appear on thermal cameras. A single paddock takes a full day to survey properly, and damaged fences mean a mob located one morning may have drifted elsewhere by the next. Exact numbers remain elusive, but the couple have tracked down what Eldridge describes as a number of mobs, and they remain camped on the station, continuing the search.

When station manager Ms Bishop returned to Quondong for the first time since the floods — road closures had kept her away for four months — she found the property unrecognisable. In January, the station had been shearing in 50-degree heat, pushing through conditions that felt punishing at the time. That decision proved to be the difference. Had shearing been delayed by even a few weeks, the floods would have made the sheep unreachable, and animals carrying a full year's wool would not have survived the inundation.

Both stations, for all the hardship and logistical complexity, are finding something unexpected in the flood's aftermath. All five of Quondong's 300,000-litre water tanks are full. The livestock are thriving. And the outback — a landscape defined by its dryness — has turned a colour its people rarely see. 'It is spectacular. It is English green,' Bishop said. Oldfield, looking out over country she has never seen looking better, calls it an absolute picture. The floods have remade the land, and for now, the land is flourishing.

Four months into a flood that refuses to recede, Sharon Oldfield stands on one side of a water-filled channel and her cattle stand on the other. Around 4,000 head at Cowarie Station, 250 kilometres north of Marree in outback South Australia, have been cut off since February by record rainfall that keeps finding new ways to stay. The main channel remains full. The floodplain beyond it is soft and boggy. Half the property is simply unreachable by road, and Oldfield does not expect that to change until September.

This is not the first time Cowarie's cattle have required a helicopter to check on them, but the duration has been unusual. The water came in waves—local rain first, then floodwaters flowing down from Queensland through the Diamantina and Georgina rivers, then those rivers rose again, and again, and then more rain fell. Each pulse kept the channel full. The cattle cannot be transported out. But when Oldfield checks on them by air, they appear unbothered by their isolation. "They're all fine," she said. "Just living the dream out there at the moment." The neighbouring station, meanwhile, has resorted to walking cattle over 100 kilometres to reach a transport point, taking the long way around what water has blocked.

At Quondong Station, 147,710 hectares of land stretches across the far east of South Australia, much of it still underwater. Finding thousands of sheep across that expanse by foot was never going to work. So the station brought in thermal drone operators—Tony Eldridge and Colleen O'Callaghan, a couple whose professional journey has taken them from dentistry and military work into a travelling security company built around drone technology. Using thermal imaging to assess flood damage and locate livestock became a natural extension of their existing work. They have been mapping which areas remain impassable, estimating when roads might dry enough for vehicles, checking fence conditions, and counting stock in paddocks so vast that the task requires systematic crisscrossing.

The merino wool that insulates the sheep creates its own problem: the animals barely register on a thermal camera. Eldridge estimates it takes a full day to properly survey a single paddock. Damaged fences add another layer of uncertainty—sheep that are in one location one day may have moved through a broken fence by the next. On a property this size, achieving perfect clarity on exact numbers is nearly impossible. Still, the couple have managed to track down what Eldridge calls "a number of mobs," and they remain camped on the station, continuing their search.

When station manager Ms Bishop returned to Quondong for the first time in four months—road closures had made it inaccessible until now—she found a landscape transformed. In January, before the floods came, the station had been shearing in 50-degree heat. She had wondered then if they were mad to push through such conditions. Two weeks later, when the rains began, that decision became a mercy. Had they delayed shearing into February, March, or April, they would not have been able to reach the stock. Sheep with a full year's wool would have drowned. Instead, the station had survived the heat, and the animals had survived the water.

Despite the access challenges and the logistical puzzle of locating and managing livestock across flooded terrain, neither station is complaining. All five of Quondong's 300,000-litre holding tanks are full. Water, which is often the scarcest resource in the outback, is now abundant. The country itself has transformed. "It is spectacular. It is English green," Bishop said. Oldfield echoes the sentiment: "I've certainly never seen it any better than it is now. It's just an absolute picture to behold." The floods have created hardship and complexity, but they have also brought something the outback rarely sees—green fields stretching to the horizon, and livestock thriving on land that has been remade by water.

The main channel is still full and the flood plain still has a lot of water on it, so we can't actually get around.

It would be near impossible on a property this big to get an absolute 100 per cent clarification of exact numbers.

The Hearth Conversation Another angle on the story
Inventor

Why does it matter that these cattle have been cut off for four months? Couldn't they just be transported out once the water recedes?

Model

The problem is they can't wait. Cattle need to be moved for market, for breeding, for management. Being stranded means lost income, lost time, lost control over the herd. And there's no guarantee the water will recede soon—it keeps rising again.

Inventor

But Oldfield said they're "living the dream." Doesn't that suggest the animals are actually fine?

Model

They are fine physically. The grass is green, water is everywhere. But that's not the point from a business perspective. A pastoralist's job is to move animals, to manage them, to sell them. Being unable to do that is a kind of paralysis, even if the animals themselves are content.

Inventor

What makes the thermal drone approach so difficult? Why can't they just count the sheep?

Model

The wool itself is the problem. Merino wool insulates so well that the sheep barely show up on thermal imaging. And the paddocks are enormous—it takes a full day to properly search one. Plus, fences are broken, so sheep move between areas. You're trying to solve a puzzle where the pieces keep shifting.

Inventor

The article mentions that Bishop was relieved they sheared in January. Why was that such a close call?

Model

If they'd delayed shearing even two weeks, the floods would have come while the sheep still had a full year's wool. Wet wool is heavy and cold. Sheep would have drowned. The timing was luck—brutal heat in January that felt pointless at the time, but it saved the herd.

Inventor

So what's the actual outcome here? Are these animals going to be okay?

Model

Yes, they'll be okay. The land is greener than anyone has seen it. Water is abundant. The real question is how long the pastoralists can sustain the separation—how long before they need to move the animals, and whether the water will let them.
