Victoria has reported nine new coronavirus cases as Melbourne enters its 11th day in lockdown.
The Victorian Department of Health and Human Services on Monday morning reported 11 cases in the 24 hours to midnight on Sunday.
Two of those cases were identified at the Arcare Maidstone aged care facility on Sunday.
The Arcare Maidstone outbreak has grown to six cases after another resident and a registered nurse tested positive.
The 79-year-old resident, who had both doses of the Pfizer vaccine, was moved to hospital as a precaution.
A first dose had been given to the registered nurse, who last worked at the nursing home on Saturday.
"The staff member had not worked at other facilities," the Department of Health said.
The Department of Health said all new locally acquired cases were linked to existing outbreaks.
Eight are existing primary close contacts who were quarantining during their infectious period.
The state reported 17,719 vaccine doses were administered while 24,265 test results were received. No new cases were acquired from overseas in the past 24-hour period.
There are now 94 active cases in the state.
The latest cases come after the state announced another two new local cases on Sunday, the lowest number in 13 days.
Monday's number is the highest daily total recorded in Victoria since lockdown began at 11.59pm on May 27.
The lockdown was announced after the state reported 12 daily cases.
It is unclear whether the latest glut of cases will dent the city's hopes of moving to eased restrictions from Friday.
Ten Melbourne suburbs on high alert
Ten Melbourne suburbs have been put on high alert after Covid-19 virus fragments were detected in sewage.
The inner west and northern suburbs of Aberfeldie, Essendon, Essendon West, Flemington, Footscray, Kensington, Maribyrnong, Moonee Ponds, Parkville and Travancore are served by the sewer catchment where the virus was detected.
Deputy Chief Health Officer Allen Cheng said these areas are of interest to authorities because "there are no confirmed cases in that area".
"There was one case in hotel quarantine," Professor Cheng said.
Thousands of residents in those suburbs are urged to monitor for symptoms as well as anyone who visited those areas.
