Escalating Mouse Infestation in Western Australia's Wheatbelt
On May 2, 2026, the Australian government announced heightened concern over a mouse infestation affecting farms across the wheatbelt of Western Australia. Officials described the situation as a “plague” that threatens both local crop yields and the broader food supply chain. The announcement came during a televised briefing in Sydney.
Historical Context of Australian Mouse Plagues
Mouse plagues have long been a recurring challenge in Australia’s grain-growing regions. The most severe outbreak on record occurred in 1993, when rodents devastated thousands of hectares of crops and attacked livestock on pig and chicken farms, according to the national science agency.
Key Actors: Government, Industry, and Science Agency
The response involves several principal parties: Energy Minister Chris Bowen, who delivered televised remarks from Sydney; grain producers operating in the affected regions; and the country’s science agency, which supplied the historical data on the 1993 plague.
Scale of the Threat: Wheat Export Role and Past Damage
Australia ranks as the world’s fourth-largest wheat exporter. The 1993 plague caused extensive agricultural loss, underscoring the risk that a similar outbreak could affect wheat production.
Potential Impact on Domestic Food Supply
Officials warned that unchecked mouse activity could reduce wheat harvests, thereby affecting food availability within Australia. The situation also raises concerns about secondary effects on livestock operations that share farm infrastructure with grain production.
Official Government Statements
Energy Minister Chris Bowen emphasized that the centre-left government remains committed to collaborating with industry partners to mitigate the plague’s effects. He described the event as a very difficult situation for farmers, industry, and governments. Bowen’s remarks were part of a broader government effort to coordinate with grain growers.
Industry Concerns and Calls for Stronger Control Measures
Grain producers, who first raised alarms in April, reported observable crop damage and called for access to more powerful mouse poison. Their statements reflect a demand for immediate, effective tools to protect yields and sustain the supply chain. Producers highlighted that existing poison options were insufficient for the scale of the infestation.
