Defence update on recent dust clouds at RAAF Base Pearce

8 March 2023

Defence is aware that earthworks related to a runway extension at RAAF Base Pearce on 7 March 2023 appear to have generated noticeable amount of dust clouds. This was a result of the laying down of topsoil.

Whilst the works are occurring at the northern section of the base and well away from PFAS source areas, Defence acknowledges the concerns local community may have about air borne dust particles emanating from Base.

Defence can confirm that no source areas as part of the PFAS management area plan were disturbed as part of the current works. 

Defence has advised contractors to increase the use of water trucks and consider wind conditions for the duration of this project to minimise dust concerns. Additionally hydromulch has also been distributed to minimise dust and encourage grass growth.

Defence is committed to being a good neighbour, minimising disruption or concern where possible to local residents.

The PFAS project team is available to speak with property owners on 1800 987 614 or email

Further information on Defence’s response to PFAS contamination on and around RAAF Base Pearce is available on the PFAS Investigation and Management Program page.

Further details on the runway extension works are available on the Infrastructure projects page.
