Australia's Fields Under Siege: Mouse Plague Devastates Crops
31 May
Summary
- Farmers face immense financial losses due to widespread mouse infestations.
- Unpredictable supply chains add to the existing pressure on agricultural operations.
- Farmers are resorting to costly baiting and replanting efforts to combat the mice.

Large swathes of Australia are currently grappling with a severe mouse plague, causing widespread devastation to agricultural fields and rural homes. This infestation exacerbates existing pressures on farmers, who are already contending with volatile fuel and fertilizer supplies due to international conflicts.
Farmers have invested significant financial resources, amounting to hundreds of thousands of dollars, in responding to the crisis. This includes the cost of replanting crops that have been entirely consumed by the rodents and the extensive use of sterile seeds laced with poison bait. Geoff Cosgrove, a farmer from Western Australia, notes the psychological toll, describing the constant presence and smell of mice as deeply unsettling.
This year's plague is reportedly far worse than the significant event experienced in 2021, which heavily impacted New South Wales and Queensland. At that time, the infestation was so severe that it caused extensive damage to a prison in New South Wales, requiring the relocation of inmates. Current reports indicate that farmers in Western Australia began noticing plague-like numbers in March, with South Australia soon following.
