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 Association 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.

Current notices 

  • EPA is removing portable air monitors that measure fine airborne particles (PM2.5) from our monitoring stations in Mooroolbark and Point Cook. A different type of monitor (nephelometers) already at these monitoring stations will be used to provide information on the PM2.5 levels on EPA AirWatch. The portable monitors being removed from Mooroolbark and Point Cook will be used by EPA to enhance our capability to respond to major air pollution incidents. (08 September 2017)
  • 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)
  • Ozone: During winter months, EPA switches off equipment that we use to monitor summer ozone in parts of our network (mostly in metropolitan Melbourne). We will switch them back on before the start of next summer. (04 April 2017).

  • 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 Mooroolbark and Point Cook. EPA staff will monitor visibility readings during periods forecast for high levels of fog and communicate any issues if required. (08 September 2017)
