What is PFAS?

  • PFAS stands for per and poly fluoroalkyl substances, which are manufactured chemicals used in products that resist heat, oil, stains and water.

  • In the past, firefighting foams containing PFAS were used by Airservices and other organisations due to their effectiveness in fighting liquid fuel fires.

  • Airservices began transitioning away from PFAS-containing foams in the early 2000s after becoming aware of potential environment impacts.

  • Airservices has been using PFAS-free foam at Cairns Airport since 2010. Airservices is Federal Government agency and PFAS remediation is their responsibility.

 

How does PFAS affect Cairns Airport?

  • As with many airports around Australia, traces of PFAS have been detected in sites on and adjacent to Cairns Airport.
  • Airservices continues to conduct site investigations at Cairns Airport, including sampling of soil, groundwater and surface water. Airservices is due to complete a detailed site investigation in 2024.
  • Cairns Airport commissioned and funded our own independent assessment, which tested samples from some fish species at Middle Creek near Cairns Airport.
  • We received this report in February 2024. It shows low levels of PFAS were detected in some fish from the creek.

  • Cairns Airport shared this report with Queensland Health. Queensland Health has reiterated that fish is an important part of a healthy diet and should come from a variety of sources.

  • Queensland Health have advised: “Proactive messaging is not recommended at this stage based on the data available for Middle Creek.”

How is Cairns Airport managing PFAS?

  • Cairns Airport manages PFAS in accordance with the National Environmental Management Plan and follows guidelines from the Department of Environment and Science (DES), including for construction and development activities.

  • We conduct our own PFAS sampling, in conjunction with and subject matter experts and Traditional Owners. These results are shared with Airservices and other relevant agencies. Testing is also undertaken as part of our regular internal General Environmental Monitoring, and baseline contamination assessments are conducted prior to any development or lease renewal.

  • Cairns Airport is committed to transparent communication, guided by information provided by Airservices and Queensland Health. A community information session, led by Airservices and Queensland Health, is expected after the detailed site investigation report is released.

  • We have asked Airservices to clean up the PFAS contamination at Cairns Airport.
