COVID-19 wastewater monitoring and statistics
Monitoring
Queensland Health used wastewater surveillance to monitor SARS-CoV-2, the virus that causes COVID-19.
When there was either no or very low COVID-19 transmission in Queensland, wastewater surveillance was primarily used as a tool to detect the presence of COVID-19 in a geographic area.
Results were useful to guide the public health response. For example, if wastewater samples in a certain geographic area were positive for COVID-19, but there were no known community cases, Queensland Health was able to focus on increasing testing in that area to try to identify, and then contact trace, the positive cases.
When there was widespread COVID-19 transmission in Queensland, wastewater surveillance was used to measure the overall incidence of COVID-19 in a community.
Wastewater surveillance data from these periods can be accessed on the Queensland Open Data portal.
Between January 2023 and December 2025, wastewater surveillance was used to monitor new variants of COVID-19 in Brisbane, Cairns, the Gold Coast, Logan and the Sunshine Coast.
Further wastewater surveillance activities are expected in Queensland, starting in 2026. This will take place as a part of a National Wastewater Surveillance Program. Learn more from the Australian Centre for Disease Control.
