The stench of death hangs over the New South Wales grain belt. Not from drought or bushfire, but from a biblical plague of mice. Farmers report fields crawling with rodents, crops gnawed to stubble, and grain silos turned into seething, squeaking tombs. ‘It’s like a decaying body,’ one grower told me, his voice flat with exhaustion. ‘You can smell them before you see them. The noise at night, it’s a constant scratching, like the earth itself is trying to chew its way out.’
This isn’t a freak weather event. It’s a man-made disaster, years in the making. Sources close to the agricultural ministry confirm that the mouse explosion follows a perfect storm of policy failures and corporate short-sightedness. Farmers, squeezed by supermarket duopolies and rising input costs, abandoned traditional crop rotations. They planted wheat on wheat, year after year, creating a monoculture buffet. The mice, with their legendary reproductive speed, did the rest. A single female can produce 350 offspring in a season. This season, there’s no predator to stop them.
Documents obtained by this newsroom reveal that the Australian Pesticides and Veterinary Medicines Authority approved the use of a potent rodenticide known as ‘bromadiolone’ last autumn, despite warnings from ecologists that it would poison native raptors. ‘We told them it was a stopgap,’ a former APVMA scientist told me, speaking on condition of anonymity. ‘But the farming lobby wanted a quick fix. Now we have dead owls and eagles, and the mice are back stronger than ever. They’re evolving resistance.’
On the ground, the scenes are straight out of a horror film. In the town of Dubbo, a local pub owner showed me footage of hundreds of mice swarming over his bar top, ignoring the bartender’s broom. In Walgett, a private school was forced to close after mice chewed through electrical wiring, causing a small fire. But it’s the farmers who bear the worst of it. One family, the Harrisons, lost their entire winter crop – 2,000 acres of wheat – in six weeks. ‘We’re looking at a $400,000 loss,’ Joe Harrison said, his hands trembling as he held a trap overflowing with carcasses. ‘The bank is calling in our loans. We might have to sell the farm.’
The economic fallout is staggering. Australia is the world’s second-largest exporter of wheat. The National Farmers’ Federation estimates that the plague could cost the sector $1 billion in lost production this year alone. But the real damage goes deeper. Mice carry leptospirosis and hantavirus; contaminated grain can cause salmonella outbreaks. Health authorities have already reported a spike in cases of ‘mouse urine allergy’ syndrome, a potentially fatal respiratory condition.
Where is the government? The federal agriculture minister, David Littleproud, has announced a $10 million emergency fund – a pittance, critics say. The real money, the kind that buys effective control, remains tied up in corporate interests. Sugar and cotton giants like Wilmar and Olam have lobbied against restrictions on monocropping, arguing it would hurt ‘efficiency’. Meanwhile, the farmers who feed the nation are left to drown in a sea of rodents.
One agronomist I spoke to summed it up bluntly: ‘This is what happens when you let the market decide everything. The mice are just the symptom. The disease is profit over people.’
As night falls over the plains, the scratching begins again. It’s a sound that has become a countdown. Not to a scandal, but to a collapse. And no one in a suit seems to care.
