We publish all validated reports based on our agreements with governments, and the relevant environmental authority in each state.
All validated environmental and air quality reports for Queensland toll roads and tunnels are published below.
Our monitoring systems provide the most up-to-date air quality data for our tunnels and roads.
For a snapshot of current air quality visit:
The data used on these pages is collected by third parties using equipment which is not controlled by Transurban Queensland and as such may be subject to faults or errors by third parties, external weather or environmental events, or server access issues.
The data comes directly from the air quality monitoring instruments and sensors and has not been validated and may be adjusted at a later time through a standardised procedure to account for instrument errors. Once data has been validated, a validated data report are posted on the air quality reports page.
