No new locally acquired cases of COVID-19 have been found in NSW in the latest 24-hour reporting period.
The state's only two new cases were detected among international travellers in hotel quarantine, bringing the total number of cases in NSW to 4256.
There were 18,466 tests carried out in the 24 hours to 8pm on Wednesday.
NSW Health has thanked the community for coming forward to get tested, and has conitnued to urge communities in south-west Sydney to remain vigilant.
As the state heads into the festive season, it continues to urge everyone with even the mildest of symptoms to do so, "as it allows us to detect cases early and prevent onward transmission".
The department also said it is continuing contact tracing to contain the recent cluster of cases, which it said depends on businesses having effective COVID Safety plans and customer sign in processes.
From late November, all hospitality businesses in NSW will need to use QR codes to sign in customers.
"The recent cluster in South Western Sydney highlights the importance of these measures," it said.
"NSW Health is working in close cooperation with a number of other agencies to provide the Liverpool community and local businesses with extra support to help achieve COVID-safe practices"
NSW Health is treating 68 COVID-19 cases. One patient is in intensive care and is being ventilated. Ninety-one per cent of cases being treated by NSW Health are in non-acute, out-of-hospital care.
