'While the number of locally acquired cases recorded in the past 24 hours is low, the virus is likely circulating among people in the community with mild symptoms,' the department said.
'As such, the risk of outbreaks and a resurgence of cases remains.
'It’s vital that everyone who does have the virus is tested and diagnosed, in order to stop further spread to others.'
Four people are currently being treated in the intensive care unit with two of them placed on ventilators.
'NSW Health is again urging anyone feeling unwell – even with the mildest of symptoms such as a runny nose or scratchy throat – to come forward and get tested, so cases in the community are identified as quickly as possible,' the department warned.
Five cases of COVID-19 were recorded in the state on Thursday.
One of the cases had attended the Eastern Suburbs Legion Club in Waverley in Sydney's eastern suburbs.
Diners who attended a Thai restaurant in Casula in Sydney's south-west were also urged to get tested immediately.
