As many as 340,000 New South Wales residents have been urged to be on high alert for signs of COVID-19 after fragments of the virus were found in wastewater samples.
The state on Saturday reported a sixth consecutive day without a locally acquired infection.
However, more traces of the virus were found in wastewater samples at two separate treatment plants.

The plants are in Liverpool and Glenfield - which service around 180,000 and 160,000 residents respectively.
“While this likely reflects known recent confirmed cases in these areas, NSW Health urges everyone living or working there to monitor for symptoms and get tested and isolate immediately if they appear,” the health body said in a statement.
More than 11,300 test results were processed in the 24 hours to 8pm on Friday.
One additional case was reported in a returned traveller in hotel quarantine.

New South Wales Premier Gladys Berejiklian, meanwhile, has promised to ease COVID-19 restrictions if cases remain low, with the new rules likely to be as close as possible to those in place before the Avalon outbreak.
“Please know that if things continue the way they are, by this time next week there will certainly be decisions made around getting us as close as possible to pre-Avalon conditions,” she told reporters on Wednesday.
December’s Avalon outbreak caused the government to clamp down on numbers for both indoor and outdoor gatherings in Greater Sydney, the Central Coast and Wollongong.
Restrictions for weddings, funerals and religious services were also bolstered.
Greater Sydney, Central Coast and Wollongong residents have also had to wear masks indoors when out of the home for the past few weeks.
