*Please note that the Quinns Rocks air quality monitoring station is being relocated due to land use changes in the area. Earthworks at the new Quinns Rocks site are due to start mid-late January 2020, and we expect the new site to be fully operational later in 2020.

The Busselton air monitoring station is being taken off line in March 2020 to allow ground works to be undertaken by the local authority. The department will use this down-time to upgrade the sites air monitoring instruments. The resumption of monitoring at Busselton is expected to be later in 2020.
