QLD Acting Chief Health Officer Dr Bennett says the fragments of SARS-CoV-2 have been detected in the Gold Coast catchments of Pimpama, Coombabah and Merrimac, but it's possible these detections are not current.
Dr Bennett says it's critical we find any sources of coronavirus through the testing mechanisms as quickly as possible.
Queenslanders who have been in New South Wales since 2 February should come forward and get tested if they experience any symptoms.
