Forever chemicals, scientifically known as PFAS (per- and polyfluoroalkyl substances), are a group of synthetic compounds that have been used since the 1950s in products like non-stick cookware, waterproof fabrics, food packaging, and firefighting foam. They’re known as “forever chemicals” because they don’t break down easily in the environment or the human body, meaning they can persist for decades and accumulate over time. In Australia, PFAS contamination has been discovered in several areas—most notably near airports, military bases, and industrial zones. These chemicals were commonly used in firefighting foam, and over time, they’ve seeped into soil, groundwater, and in some cases, even drinking water. Regions in New South Wales, Queensland, and Victoria have all reported contamination, often linked to historical Defence Department activities.
While studies are still ongoing, international research has raised serious concerns about PFAS exposure. Long-term contact with high levels of PFAS has been associated with liver damage, thyroid issues, immune suppression, elevated cholesterol, and potentially an increased risk of certain cancers. Australia’s Department of Health maintains that most Australians are only exposed to low levels, but they recommend taking a precautionary approach, particularly in affected communities.
Risks:
- Liver damage
- Thyroid issues
- Immune suppression
- Elevated cholesterol
- Certain types of cancers
How Can You Reduce Your Exposure?
If you’re worried about PFAS, especially in your drinking water, there are steps you can take. Start by checking with your local water authority or council for updates on PFAS levels in your area. For added peace of mind, consider using a certified water filter—particularly those using activated carbon or reverse osmosis, which are proven to reduce PFAS. You can also reduce exposure by avoiding PFAS-containing products like non-stick pans, stain-resistant fabrics, and certain food packaging.
A Growing Awareness in Australia
Awareness of forever chemicals is growing rapidly across the country. As testing improves and new information comes to light, more Australians are seeking ways to limit their exposure and protect their health. Whether it’s choosing safer household products or investing in a reliable water filtration system, every step helps.

Australia has begun addressing PFAS contamination through both policy and cleanup efforts. The government released a National PFAS Position Statement, and the Department of Defence has launched investigations and remediation projects at over 20 sites. Some states have banned firefighting foams containing PFAS, and there’s growing pressure to limit PFAS in imported goods and consumer products.
