Bushfire Smoke and Air Quality Strategy, 2021-2025

On 11 November 2021 the ACT Government released its Bushfire Smoke and Air Quality Strategy - a whole of government approach to prevent, prepare for, respond to, and recover from significant bushfire smoke events and our management of the smoke from wood heaters.

The strategy sets out key actions over the next four years, including : strengthening wood heater emission standards, enhancing air quality monitoring and forecasting, identifying and supporting smoke refuges and providing economic support to those affected by severe bushfire smoke.

This page includes information about air quality in the ACT, including health advice related to specific pollutants that are measures in the ACT, as well as health advice related to pollen.

Current air quality

Air quality raw data for ozone, CO, NO2, PM10  and PM2.5 ­can be found on the Air Quality in the ACT page. You can also find information about each pollutant and how it is measured on the monitoring pages.

Particulate matter PM2.5

The table below shows the hourly rolling averages for PM 2.5 at the Canberra air quality monitoring stations by health categories. Go to the next section to find the current health and activity advice for PM2.5.

Health and activity advice for particulate matter PM2.5

The health and activity advice below is based on air quality health categories for PM2.5. Simply match the current air quality colour rating (above) to the colour in the table below to find the current health and activity advice for PM2.5. PM2.5 levels can change rapidly, depending on the source and weather patterns.

During bushfire season be sure to check the ACT Emergency Services Agency website for information about fire ratings, fire bans and bushfire events.

For more information about the health impacts of outdoor smoke, see our Outdoor smoke - Health impacts fact sheet.

Background on PM2.5 Health Advice

  • Australian State and Territory Governments are working together to produce nationally consistent health advice for the key air pollutants that are of concern to the health of Australians.  This webpage will be updated as these categories are agreed to.  The first pollutant with agreed categories is PM2.5, which is the main pollutant of concern during bushfire events.
  • From December 2020 ACT Health implemented air quality categories for particulate matter 2.5 (PM2.5) that correspond to nationally agreed health and activity advice. From December 2020, ACT Health now provides health advice for PM2.5 ­based on hourly rolling averages. Hourly averages correlate closely to current levels of PM2.5 in the air.

If you use AirRater, which tells you PM2.5 concentrations in the ACT, you will note an extra category that is not included in the ACT health categories will sometimes show up that is in between the ACT Health category of ‘good’ and ‘fair’. This extra category shows up in AirRater when PM 2.5 concentrations are between 11 – 25 uq/m3.  When concentrations are in this level, there is no specific health advice that is required.  However, it may be an indication that air quality is changing.  It may be beginning to get worse, so you may like to keep an eye on conditions, especially if you are more sensitive to the effects of PM2.5. On the other hand, if the air quality has been much worse and it is now improving, it may be a good time to open and air out your house.

Pollen

If you would like to see the grass pollen count for today and the forecast for the next 6 days, visit the Canberra Pollen Count and Forecast Service. You can also download the AirRater app This free app provides users with up-to-date information on total pollen (including tree and grass pollens), smoke pollution and temperature in the ACT. Please note that pollen levels may vary between AirRater and the Canberra Pollen Count and Forecast Service from time to time. These differences arise because AirRater measures total pollens and Canberra Pollen Count and Forecast Service measures grass pollen only.

Health advice for pollen and thunderstorm asthma

Please see the pollen allergy page.

Health and activity advice for ozone

Exposure to elevated levels of ozone increases inflammation in the body, including inflammation in the airways and can cause damage to the lining of the airways.  This can lower lung function (making it feel difficult to breath), increase airway hyper-responsiveness (a feature of asthma) and decrease clearance of infections from the lungs.  All these things make people more likely to have respiratory symptoms, like coughing, throat irritation, and chest tightness, when they are exposed to ozone.

Ozone affects all people, including healthy people.  However, some people are more sensitive to ozone exposure than others, including people who have existing lung conditions, children, and people over the age of 65.

Ozone levels are more likely to be elevated  during the summer, particularly on hot days in the afternoon and early evening.  On very hot days when ozone levels are likely to be higher in the afternoon and early evening, even healthy people should try to plan their more vigorous exercise for the morning, if possible.

If you are sensitive to the effects of ozone or you have an underlying respiratory condition, make sure you have an asthma or COPD action plan with your general practitioner; take your preventer medications and reliever medications as prescribed.

If you are concerned about symptoms call the 24-hour HealthDirect helpline on 1800 022 222 or see your doctor.

If you or anyone in your care has trouble breathing or tightness in the chest or in a health emergency, call 000 for an ambulance.
