Current notices

  • Moe: monitoring for PM2.5 is offline due to routine maintenance and PM2.5 data is not being collected at this station. EPA expects data to become available on the website from 5pm, 18/10/2019. The air quality forecast for Latrobe Valley is expected to be GOOD to VERY GOOD (16 October 2019)
  • Newborough: Monitoring for PM2.5 is offline due to technical difficulties and PM2.5 data is not being collected at this station. EPA technicians are working to fix the problem. (16 October 2019) 

  • Altona North air monitoring station will be offline temporarily while the station is relocated nearby. Until the new site is established air monitoring information for Altona North will not be displayed on AirWatch.  Air Quality information for Footscray, Brooklyn and Point Cook is available on the AirWatch website.  An Air Quality forecast for the next 24 hours can be found at (26 June 2019)
  • Fog can cause low visibility readings in EPA’s air monitoring network due to high levels of moisture in the air. Fog may also affect PM2.5 readings at Brooklyn, Dandenong, Macleod, Mooroolbark and Point Cook. EPA staff will monitor visibility readings during periods forecast for high levels of humidity and communicate any issues if required. (02 April 2019)
  • Latrobe Valley: Given the Hazelwood power station is now closed and there are no longer any discharges from the power station chimneys, ENGIE is no longer obliged to monitor air quality from the chimneys. However, EPA licence requirements remain in place to ensure monitoring of other environmental risks, including fugitive dust, and annual reporting that occurs through the 2016–17 annual performance statement. EPA’s Latrobe Valley air monitoring network – with stations at Morwell South, Morwell East, Churchill, Moe and Traralgon – will also help EPA track any changes in local air quality since the closure. (19 April 2017)

Disclaimer: Data on EPA AirWatch comes directly from our air monitoring stations using various types of monitoring equipment and methods. This data may be adjusted later according to set criteria to account for instrument errors, power interruptions and other technical issues.

Siting: EPA aims to locate our ambient monitoring stations so they give a good representation of the air quality experienced by the public. As most of the Victorian population lives and works close to roads, most of our stations are in population centres next to roads. This can mean we do not always comply with one of the requirements of the Australian Standard for siting (AS 3580.1.1), which specifies that air monitoring stations should be more than 50 metres away from a road. Currently, Footscray is the only EPA air monitoring site that meets this requirement.

Air quality impacts from planned burns

Forest Fire Management Victoria and Country Fire Authority crews conduct planned burns to reduce bushfire risk to communities and the environment. Smoke impacts from planned burns can result in poor air quality across parts of Victoria.

For the latest information about when planned burns are happening near you, visit,, download the VicEmergency app or call the VicEmergency hotline on 1800 226 226.

For information on how to minimise health impacts of smoke, visit the Department of Health and Human Services website.
