Rural air quality network - Live air quality data

Hourly updated particle concentrations from indicative monitors.


  • Bushfire season has started in NSW. Please monitor Fires Near Me by the RFS for the location of fires. NSW Health and the Bushfire health advice tab, below, provide information on how to protect yourself from bushfire smoke.
  • Daylight savings: live data is reported in Standard Time (AEST), and not in Daylight Savings Time (AEDT). Please add an hour to the displayed time to convert to local NSW time.
  • New South Wales is now reporting hourly averages for PM10 and PM2.5. More information


  • CMA – Catchment Management Authority
  • LLS – Local Land Services
  • SA – South Australia
  • TSP – Total Suspended Particles

Instruments used

Multi-channel DustTraks are used for stations reporting TSP, PM10 and PM2.5. Single-channel DustTraks are used for stations reporting TSP only. An ongoing upgrade is underway to replace all NSW sites with multi-channel instruments.


Most rural network stations use mid-cost indicative monitors which respond to all aerosols including dust, sea salt and smoke. Single-channel DustTraks (TSP only) will also respond to fog.

We have undertaken best efforts to ensure that data from these instruments is consistent with measurements from compliance instruments. However, note that instrument accuracy does not meet strict Australian Standards, therefore care must be taken in interpreting the data compared with Air NEPM standards without additional information. Reported data has only undergone preliminary automated checks, and further manual validation is performed for data stored in the DPIE database.

Data is reported in Australian Eastern Standard Time (AEST), and updates approximately 30 minutes past the hour (e.g. 11:00 values are online at approximately 11:30). However, during daylight saving, data is still collected and stored in AEST and will be presented with an apparent 90 minutes delay. Gaps indicate that a pollutant is not measured at the site OR instrument was offline OR that wireless or satellite connection was not able to be established with the site.
