Escalating Mouse Plague in Western Australia
On May 2, 2026, the Australian government announced heightened concern over a surge of mice infesting farms across the wheatbelt of Western Australia. The rodents have been reported to damage grain crops, prompting officials to label the situation a “plague.” The government pledged to continue working with industry to mitigate the impact on both domestic and overseas food supplies.
Background: Historical Outbreaks and Grain Production
Mice infestations have long been a recurring challenge in Australia’s grain-growing regions. The most severe episode occurred in 1993, when a mouse plague destroyed thousands of hectares of crops and attacked livestock on pig and chicken farms, according to the national science agency. Australia remains the world’s fourth-largest wheat exporter, making any disruption to its wheatbelt a matter of national and international significance.
Key Figures: Energy Minister Chris Bowen and Grain Producers
Energy Minister Chris Bowen, representing the centre-left government, delivered televised remarks from Sydney outlining the administration’s response. Grain producers, who issued warnings in April, have called for access to more powerful mouse poison to protect their yields.
Data & Statistics
- Australia ranks fourth globally in wheat exports.
- The 1993 mouse plague resulted in the loss of thousands of hectares of crops (exact figure not specified).
- Current reports describe widespread infestation across the Western Australian wheatbelt, though precise rodent population numbers are not provided.
Potential Impact on Domestic and International Food Supply
Officials warn that unchecked rodent damage could reduce wheat output, affecting supply chains that serve both Australian markets and overseas buyers. A reduced harvest could affect the availability of wheat for export.
Official Government Response
The government affirmed its commitment to collaborate with agricultural stakeholders, emphasizing ongoing efforts to limit the plague’s effect on food security. Energy Minister Bowen reiterated that the situation is “very difficult” for farmers, industry and governments, and said the administration will continue working with industry to mitigate the impact on both domestic and overseas food supplies.
Industry Concerns and Calls for Stronger Rodenticides
Grain producers have publicly urged the government to permit the use of more powerful mouse poison, arguing that existing controls are insufficient to curb the rapid spread of the infestation. Their appeals underscore tension between regulatory caution and the need to protect crops.
