Australian Government Files $2 billion Lawsuit Against 3M Over PFAS Contamination at Defence Bases

Lawsuit Overview
On 28 May 2026 the Commonwealth filed a Federal Court claim seeking more than A$2 billion in damages from 3M Australia and its parent. The suit alleges the company’s aqueous-film-forming foam (AFFF), used at 28 Defence sites from the 1970s until its 2003 phase-out, released PFAS that have persisted in soil, water and the food chain. The government says the chemicals have generated “significant past and future expenses” for investigation, remediation and health protection.
PFAS Background
PFAS are synthetic “forever chemicals” that resist heat, stains and water, do not break down naturally, and accumulate in ecosystems. Exposure is linked to high cholesterol, low birth weight, liver damage and higher risk of testicular and kidney cancer. AFFF containing PFAS was the standard firefighting agent for military aircraft and training for over three decades before Australia began phasing it out in 2003.
Key Parties
Attorney-General Michelle Rowland and Assistant Defence Minister Peter Khalil represent the Commonwealth; 3M Company is the defendant; affected towns include Katherine (NT), Oakey (QLD) and Williamtown (NSW).
Extent of Contamination
PFAS contamination spans 28 bases; over 200,000 tonnes of soil and 13 billion litres of water have been treated. The Commonwealth has spent over A$1 billion on investigation, remediation and mitigation. Prior payouts total A$710 million: A$132 million to ~30,000 claimants, A$212 million for property loss in Katherine, Oakey and Williamtown, and A$366 million to settle class actions. In 2018, residents near Richmond Air Base were advised to limit fish and egg consumption after PFAS was found in groundwater.
Government Position
The Commonwealth says 3M knowingly misrepresented the foam as biodegradable and non-toxic while withholding internal tests showing adverse effects. The claim seeks to recover costs and fund future cleanup, matching a Senate inquiry recommendation that any settlement be earmarked for remediation.
Criticism & Opposition
3M says it has been an industry leader in PFAS regulation and removal, disputes the concealment claim, and has not admitted liability or commented to Reuters.
Conflicting Details
Sources differ on the claim amount—some say “more than A$2 billion,” others “over $2 billion.” Whether punitive damages are included is unclear, and 3M’s scientific evidence on foam safety has not been disclosed.
