Live air data

The Queensland Department of Environment and Science (DES) in collaboration with industry partners operates an air quality monitoring network across the state.

Data from the monitoring network is presented online as ambient concentration, air quality categories and smoke and dust health action levels which are updated hourly.

What’s new

Queensland has moved to using air quality categories rather than an air quality index as part of initiatives to ensure consistent air quality reporting across Australia. The category system colours provide users with general guidance on exposure risk during pollution events. Read more about air quality categories.

Health action level information is now presented using an improved layout on a separate smoke and dust health action levels page. The health action level ranges have been updated to reflect the latest Queensland Health recommendations.

The NEPM guidelines for ozone, nitrogen dioxide and sulfur dioxide have been updated to represent the latest national standards.

Air quality data is available from 1 January 2016. Individual stations have been monitoring for different time periods so data may not be available for all possible times.

The data used to compile this air quality information comes directly from the department's air monitoring network and has only undergone a preliminary quality check. Data is retrieved from the stations every hour and after quality checks, is available approximately 1 hour later.

All data on this site is shown in Australian Eastern Standard Time (AEST).

About air quality categories

Air quality categories are used to make it easier to interpret air quality data by reducing the complexity associated with different pollutant concentration units and air quality guideline values.

Each air quality measurement from a monitoring station is assigned an air quality category rating based on comparison of the measurement value against the relevant air quality guideline. Five colour-coded air quality categories are used, being 'Good' (green), 'Fair' (yellow), 'Poor' (orange), 'Very Poor' (red) or 'Extremely Poor' (dark red). Values greater than the air quality guideline will be appear as ‘Poor’, ‘Very Poor’ or ‘Extremely Poor’.

About these Organics parameters


Benzene is an organic compound occurring naturally in fossil fuels and entering the atmosphere from both natural processes and human activities that involve the combustion of organic matter. Long-term exposure results in an increased incidence of blood and immune system disorders, including anaemia and leukaemia.

The guideline for Benzene is 250ppb (24hr avg).

Benzene is measured in parts per billion.

Toluene is a colourless organic liquid. Burning organic matter, such as wood, coal and petroleum products generates toluene, and it occurs naturally in crude oil. Motor vehicle emissions are the main source of toluene in the urban air environment, although evaporative losses from fuel storage facilities and service stations, as well as the use of toluene-based solvents and thinners are other contributors.

The guideline for Toluene is 1000ppb (24hr avg).

Toluene is measured in parts per billion.

Burning organic matter, such as wood, coal and petroleum products generates xylene, and it also occurs naturally in crude oil. Motor vehicle emissions are the predominant source of xylene in the urban air environment.

The guideline for Xylene is 250ppb (24hr avg).

Xylene is measured in parts per billion.

Formaldehyde in its normal state is a colourless gas. Low levels of formaldehyde are part of naturally occurring decomposition processes. In urban environments formaldehyde emission sources include motor vehicle exhaust, domestic solid fuel and gas combustion, goods manufactured with formaldehyde-based glues and resins and tobacco smoke.

The guideline for Formaldehyde is 40ppb (24hr avg).

Formaldehyde is measured in parts per billion.
