State of Environment
This dashboard provides an overview of the state of the Cairns environment, including Cairns Regional Council’s environmental and urban sustainability initiatives and performance in 2021/22.
The report draws data from various sources to present a detailed picture of the Cairns environment, including graphs tracking water and energy consumption, annual average rainfall and temperature, development and growth, and waste and recycling. Click, hover, or tap on the graphs to zoom in, see numerical data points or enlarge them to full screen mode.
The report shows the conditions of the local environment, the pressures on the environment and responses to those pressures - an approach commonly used in State of Environment reports.
Click or tap the titles below for more information on each topic (E.g. Climate, Water, etc.).
While State of Environment reporting is not a statutory requirement of local governments in Queensland, Cairns Regional Council considers this to be best practice. This is the 16th release of the report, and the second since moving to an interactive online format. Both the Queensland Government State of Environment and Australian Government State of Environment reports can be accessed online for further information at wider bioregional and national levels.
The report does not provide a complete summary of work done by other agencies in local catchments within the Cairns Local Government Area boundary.
Further information on these agencies can be found on the relevant websites and many are linked to from within these webpages.
This report has been produced by Cairns Regional Council and endorsed at the Planning and Environment Committee meeting on 12 July 2023.
Please note that while every effort has been made to ensure that the information contained within this report is correct and up to date, Cairns Regional Council and all persons acting on its behalf in preparing this report accept no liability for the accuracy or inferences from the material contained in this publication, or for any action as a result of any person’s or group’s interpretations, deductions or conclusions relying on this material.

These figures are based on waste audits conducted annually around the same time of year and on similar geographic regions. As the audits are limited in scope, they are not necessarily indicative of region-wide waste disposal behaviour.

* Updates to National Greenhouse and Energy Reporting scheme (NGERS) methodologies provided by the Clean Energy Regulator led to improved accuracy in wastewater treatment fugitive emissions calculations. The updated methodology suggests that previous figures for this emissions source were overestimated, as can be seen in the data for years prior to 2021/22.

About the reporting
State of Environment reporting is constantly being strengthened for increased readability and accuracy. The latest report records the most correct data as new knowledge becomes available. Data discrepancy between reports can be due to a range of factors including de-amalgamation with Douglas Shire, improved data collection, access to new information and changed procedures. Please refer to the latest report for the most up to date data.
