NSW recorded 21 cases overnight on Friday from more than 25,000 tests as two clusters are continuing to grow: Potts Point (19 people) and the Thai Rock Wetherill Park cluster (94 people).
At least four more venues have been added to the list of Sydney pubs, clubs, restaurants and cafes attended by people with the coronavirus.
A person, who tested positive for COVID-19, attended The Apollo Greek restaurant in Potts Point on Saturday, and then went went to the Harpoon and Hotel Harry pub on 26 July.
NSW chief health officer Dr Kerry Chant on Friday said authorities had found the COVID-19 link between the two Thai Rock restaurants at Wetherill Park and Potts Point, with the virus subsequently introduced to The Apollo.
She said that despite the legal 20-person cap in NSW on indoor and outdoor gatherings, people should limit gatherings to 10 people.
