NSW has recorded 11 new cases of coronavirus, six of which are locally acquired.
Of the six new community cases reported on Thursday, four are linked to a known cluster.
Five infections were also recorded in hotel quarantine, bringing the total number of cases seen in NSW to 4,132.
Thursday's figures came after new health alerts were issued for a Westfield shopping centre and two tutoring sites in Sydney's west.
NSW Health says anyone who visited the Al-Jabr maths tutoring centre at Auburn on 8 and 11 October is considered a close contact and must get tested immediately and isolate for a full 14 days, regardless of the result.
The critical times are available on the department's website.
The same alert applies for anyone who visited ACE Tutoring at Parramatta on 10 October between 9.30 am and 1.20pm.
Anyone who attended Westfield Mount Druitt on 12 October between 11.30am and 1pm is considered a casual contact and must monitor for symptoms and get tested immediately if they develop.
Premier Gladys Berejiklian announced 13 new cases on Wednesday, two of which were diagnosed in hotel quarantine, and warned the state was on the verge of an outbreak.
"This is the most concerned we've been since that first incident when the Victorian citizen came up, infected his colleagues and went for a drink at a hotel," she told reporters.
"Our state is on the verge of being where it was when we had the first seeding incident from Victoria."
Nine of the new cases were linked to an emerging cluster at a Lakemba GP clinic, which now numbers 12 cases. All are household contacts of known cases.
Hundreds of patients who visited the practice are now being tracked down by contact tracers.
Ms Berejiklian had hoped to announce increases to limit on venue bookings and the number of people who can attend weddings but will now hold off.
On Tuesday, the NSW government announced hospitality restrictions would be eased from Friday with up to 500 people allowed to attend open-air concerts, so long as they stay seated and remain four metres apart.
Restrictions for outdoor dining venues will also be relaxed, allowing one patron per two square metres, as long as venues use an electronic QR code to record patrons' contact details.
NSW Health Minister Brad Hazzard said health authorities want upwards of 20,000 people to be tested each day - about 4000 more than were tested in the 24 hours to 8pm on Tuesday.
