The number of locally-acquired COVID-19 cases in NSW is likely to spike over the weekend despite Greater Sydney approaching its fourth week of lockdown.
NSW recorded 97 new local virus cases in the 24 hours to 8pm on Thursday, with at least 46 out in the community for part or all of their infectious period.
The outbreak has passed 1000 cases since it began on June 16.
Premier Gladys Berejiklian on Friday said she expected the number of daily infections to surge again over the weekend, adding lockdown won't end until the number of infectious people in the community nears zero.
She also stressed the NSW government "will not hesitate to go harder" on current restrictions to further reduce mobility, should it be required.
The Australian Medical Association on Friday called for a harder NSW lockdown, including the closure of all non-essential retail and business activity. It also wanted stronger limits on travel distances from home.
But Ms Berejiklian said any new restrictions should have a clear health benefit.
"We need to make sure that any decisions we take will have the desired effect of reducing those numbers," Ms Berejiklian told reporters.
"The worst thing we could do is put in additional measures which don't have the desired effect ... that is why it is important for us to focus on the data."
Three quarters of the new cases were recorded in the Fairfield local government area, which has become the epicentre of the outbreak.
More than 77,000 tests were recorded on Thursday - a new record.
NSW police handed out 164 enforcement notices on Thursday and gave more than 200 warnings to people breaching the public health orders. Officers would be out in force over the weekend, NSW Police said in a statement.
Deputy Commissioner Gary Worboys declined to say if a NSW MP's relative was among those pinged by police amid reports the daughter of Deputy Premier John Barilaro, Domenica Barilaro, was fined $1000.
"A young lady from down at Queanbeyan was spoken to by police ... and that infringement notice was issued to her," Mr Worboys said.
Mr Barilaro was tight-lipped when asked if anyone in his family had been fined.
"They're private citizens and I'll leave it at that," he told Sky News.
Another man was fined for what police described as a "pop-up party" at Manly, while ex-boxer Anthony Mundine was also reportedly fined.
NSW Health has confirmed a healthcare worker at Liverpool and Campbelltown Hospitals returned a positive test to COVID-19, following a patient testing positive. Non-urgent surgery has been postponed at both hospitals.
Three paramedics in southwest Sydney have also tested positive for the virus, forcing at least 70 paramedics identified as close contacts into isolation.
The Australian Paramedics Association NSW wants specialist ambulance cleaning teams at major NSW hospitals, high-grade personal protective equipment for paramedics and improved travel planning.
"When a paramedic is exposed to workplace risk, they bring that risk back to home, to their community, as well as every patient they attend that day and every hospital they visit," APA NSW president Chris Kastelan said.
NSW Health has opened a new coronavirus vaccination hub that will prioritise about 12,000 teachers, school staff and aged care workers in southwest Sydney at the Prairiewood Youth and Community Centre.
Prime Minister Scott Morrison lauded the southwest Sydney community for their compliance with public health orders over the past week.
There are 18 COVID-19 patients in intensive care, five of whom on ventilators.
New exposure sites were on Friday evening issued for several venues, most notably the Woolworths Lennox Shopping Centre in Emu Plains, Service NSW at Liverpool, Coles at Hurstville and a Lakemba butcher.
IKEA at Marsden Park was also listed as an exposure site.
