Australia entered a new regulatory era for PFAS management in 2025, implementing a comprehensive import and manufacture ban on three legacy PFAS compounds and updating its national framework for PFAS site investigation and remediation. The combined effect of the July 2025 product ban, the March 2025 PFAS National Environmental Management Plan (NEMP) version 3.0, and updated drinking water guidelines positions Australia among the world’s more active PFAS regulators—while significant gaps in enforceable water quality standards remain.
July 2025: Import and Use Ban on Three PFAS
From 1 July 2025, the importation, exportation, manufacture, and use of PFOS, PFOA, and PFHxS—as well as related mixtures and articles—are prohibited in Australia unless a specific exemption applies. Exemptions are limited to laboratory and research contexts. This ban implements Australia’s obligations under the Stockholm Convention on Persistent Organic Pollutants for PFOS and PFOA, and reflects the addition of PFHxS to Annex A of the Stockholm Convention in 2022.
Updated Drinking Water Guidelines (June 2025)
The National Health and Medical Research Council (NHMRC) completed a comprehensive review of Australia’s drinking water guidelines for PFAS in June 2025, establishing updated health-based guideline values for four compounds:
- PFOS: 8 ng/L (revised downward from previous guidance)
- PFOA: 200 ng/L
- PFHxS: 30 ng/L
- PFBS: 1,000 ng/L
These values reflect the latest toxicological evidence and are more protective for PFOS than the previous interim guideline. The PFOA guideline of 200 ng/L is notably higher than standards in the U.S. and Canada, reflecting differences in risk assessment methodology and the specific health endpoints considered most relevant. The NHMRC guidelines inform—but do not automatically become—enforceable standards, as drinking water quality is regulated at the state and territory level in Australia.
PFAS NEMP 3.0: Updated Site Investigation Framework
The Environment Ministers of Australia agreed to publish PFAS NEMP version 3.0 in December 2024, with the document formally released in March 2025 and adopted for implementation in Western Australia and other jurisdictions in mid-2025. NEMP 3.0 updates guideline values for PFAS in soil, groundwater, surface water, and ecological receptors, and provides improved guidance on remediation technologies and the reuse of resource-recovery products from PFAS-contaminated sites.
Key changes in NEMP 3.0 include revised health investigation levels (HILs) for residential and commercial land use scenarios, updated ecological screening values, and new guidance on PFAS fate and transport modeling. The document also acknowledges the growing body of evidence on short-chain PFAS and precursor compounds, expanding the list of substances that should be monitored in contaminated site investigations.
Regulatory Gaps: No National Enforceable Water Quality Standard
Despite the advances in 2025, Australia still lacks a national, legally enforceable water quality standard for PFAS in surface water and groundwater. There is no NEPM addressing marine, estuarine, or freshwater PFAS quality. Environmental advocacy groups and state environmental protection agencies have called for urgent action to establish binding standards, noting that without enforceable limits, contamination from legacy AFFF sites, manufacturing facilities, and irrigated agricultural land continues to spread through receiving environments without clear legal triggers for remediation.
Market Implications for Water Treatment Suppliers
Australia’s tightening PFAS framework creates strong commercial signals for advanced treatment technology providers. Point-of-use PFAS filters meeting the June 2025 NHMRC guidelines—particularly 8 ng/L for PFOS—will be in high demand in regional communities near AFFF contamination plumes. Major remediation projects at Defence Department sites, airports, and fire training facilities involve treatment of PFAS-impacted groundwater at flow rates requiring granular activated carbon (GAC) systems, IX resin columns, or high-pressure membrane technology. OEM filter media manufacturers with documented performance data at Australian guideline values should proactively develop certification pathways under WaterMark and equivalent schemes.
