Australia sues 3M over $2bn PFAS contamination from firefighting foam
Consensus Summary
The Australian government has launched a $2 billion lawsuit against 3M and its Australian subsidiary for alleged misconduct related to PFAS contamination from firefighting foam at 28 defence bases nationwide. The lawsuit, announced on May 28, 2026, by Attorney-General Michelle Rowland, accuses 3M of withholding laboratory data showing adverse environmental effects and misrepresenting the safety of its aqueous film-forming foam (AFFF). The government claims over $1 billion has already been spent on cleanup efforts, and the case is the largest legal claim ever brought by the Commonwealth. While 3M denies manufacturing PFAS in Australia and claims it stopped sales around two decades ago, Defence continued using the foam for nearly two decades longer. The lawsuit focuses on environmental and economic costs, excluding personal injury claims, though previous settlements have addressed health impacts and property losses. Internationally, 3M has faced a $10.3 billion US settlement for PFAS contamination, and Australian environmental groups have welcomed the legal action as a step toward holding corporations accountable for toxic chemical pollution.

Details reported by only one source:
- Assistant Defence Minister Peter Khalil stated the case is 'solely focused on the environmental, economic and cultural impacts and the costs incurred,' excluding personal injury or health claims.
- The government alleges 3M Australia did not fully disclose environmental risks of AFFF and represented it as biodegradable and non-toxic.
- Defence has provided alternative water sources for affected communities.
- The 2023 federal government settlement for PFAS contamination included a $212 million payout for property value loss and distress in Katherine (Northern Territory), Oakey (Queensland), and Williamtown (New South Wales).
- PFAS exposure has been linked to diseases such as high cholesterol, lower birth weight in babies, and increased risk of testicular and kidney cancer.
- The chemicals are found in the blood of people and animals worldwide.
- Environmental campaigner Jon Dee from STOP PFAS welcomed the lawsuit, arguing taxpayers should not pay for a problem caused by 3M.
- University of Sydney associate professor Nick Chartres compared 3Mās actions to the tobacco industry playbook, citing internal documents showing 3M knew PFAS were toxic and persistent for decades.
- The SMH has been reporting on PFAS dangers since 2015.
- More than 200,000 tonnes of contaminated soil have been removed and treated from defence bases, and over 13 billion litres of water have been used in decontamination efforts.
- Greens spokesperson Peter Whish-Wilson called for action to prevent Australia from becoming a global dumping ground for PFAS products.
- A parliamentary inquiry last year found PFAS risks remain widespread across the country.
Contradictions
Conflicting information between sources:
- The ABC and SMH mention a $132 million settlement in 2023 for PFAS contamination at seven Defence sites, while the ABC also notes a separate $212 million payout for property value loss and distress in three communities, but NEWSCOMAU and GUARDIAN do not mention the $212 million figure.
- The SMH and GUARDIAN state 3M agreed to a $10.3 billion settlement in the US in 2023, while the ABC mentions a $12.5 billion settlement in 2024.
- The ABC and SMH mention that PFAS chemicals are found in the blood of nearly every Australian citizen, but NEWSCOMAU and GUARDIAN do not explicitly state this.
