Four residents at an aged care facility in Sydney's south have tested positive for COVID-19.
The outbreak at St George Aged Care Centre in Bexley is linked to an infected staff member.
"A staff member worked one shift while infectious on one level at the facility," Chief Health Officer Dr Kerry Chant said.

Four of the eight residents identified as close contacts have now tested positive to the virus.
All eight of the residents were vaccinated and the staff member has received their first dose of vaccination.
"Appropriate care is being provided," Dr Chant said.
The confirmation comes after New South Wales recorded its highest number of daily COVID-19 cases to date with 356 infections detected to 8pm yesterday.
Of the cases, roughly a third were active in the community while infectious, Premier Gladys Berejiklian said.
Four more people have died overnight, including a returned traveller from overseas.
None were vaccinated against the virus.
