Two new locally-acquired cases of Covid-19 were confirmed in today's NSW Health briefing, both from the Oran Park cluster.
The cluster, which is primarily related to the Great Beginnings Childcare Centre, has now reached 22 people.
Today's two cases are both linked to a person who attended Great Beginnings.
NSW Health said one of the Oran Park cluster cases visited a Macarthur Square restaurant while potentially infectious.
"NSW Health can today advise a confirmed case of Covid-19 linked to the Oran Park cluster visited Bavarian Macarthur in Macarthur Square, 200 Gilchrist Drive, Campbelltown on Saturday, October 10 from 7pm-9pm," they posted on Facebook.
"Anyone who was inside the restaurant for an hour or more during this time is considered a close contact and must immediately get tested and isolate for 14 days and stay isolated for the entire period, even if a negative test result is received.
"Anyone who dined outside the restaurant or was there for less than one hour is considered a casual contact and must monitor for symptoms and get tested immediately if they develop. After testing, they must remain in isolation until a negative test result is received."
There were more than double the number of Covid-19 tests performed in the state in the 24 hours to 8pm lats night than there were in the previous 24 hours.
Numbers jumped from 7401 tests to 14,932.
NSW is strongly encouraging people in the south-west to get tested at the first signs of potential symptoms, including coughing, a scratchy or sore throat, fever and more.
