Australia’s federal government sued 3M Company for more than $2 billion on Thursday, accusing the maker of firefighting foam of withholding and making false statements about the long-term environmental damage caused by its product. Attorney-General Michelle Rowland said the case was the largest legal claim ever brought by the Commonwealth.
The claim was filed in the Federal Court of Australia and targets foam that contained per- and polyfluoroalkyl chemicals, known as PFAS. For decades, that foam was used at Defence bases across Australia, leaving behind contamination that has spread through homes, drinking water, food supplies and vast tracts of land in dozens of communities. Rowland said, “Let me be clear, this is the largest legal claim ever brought by the Commonwealth.”
The lawsuit lands as Australia continues to confront the cost of so-called forever chemicals, a fight that has already reached into daily life for people living near contaminated sites. The scale of the problem has made PFAS one of the country’s most persistent environmental and public health issues, and the new claim raises the stakes for how much the government says 3M should pay for the damage tied to decades of use.
The case also sits alongside other pressure on PFAS policy, including a separate government action over contamination costs at 28 Defence bases and fresh debate overseas over drinking water limits for four PFAS compounds. Those fights underline how the same chemicals that sat in foam for years are now producing legal, regulatory and financial battles in more than one country.
What remains at issue is how far the federal government can push its claim against a multinational company over contamination that spread far beyond the bases where the foam was used. For the communities already living with PFAS in their water and soil, Thursday’s filing is less a starting point than a sign that the cleanup fight has entered a more expensive phase.
