UPDATE There were 13 cases, not 16 cases as initially reported, in the Hunter New England area to 8pm Friday. Hunter New England Health has confirmed that while 16 cases were announced at the 11am press conference, two have since returned negative second test results and one is not from Hunter New England. Three of the 13 cases were infectious while in the community. Seven of the cases were in Maitland, four were in Lake Macquarie, one was in Cessnock and one was in Singleton. Four are associated with the RFBI Hawkins Masonic Retirement Village in Edgeworth. The other nine are family or household contacts and linked to previously reported cases. The initial story has been updated below to reflect this information. INITIAL REPORT Saturday has been the "most concerning day" of the pandemic so far in NSW with 466 cases of COVID-19 recorded in the 24 hours to 8pm Friday. Premier Gladys Berejiklian said it was the largest jump in cases seen in a night after 390 cases were reported the day before. At least 60 were infectious in the community, but Ms Berejiklian said that number was likely to go up. "It's fair to say we that are on a par of being extremely concerned about the situation we're in in NSW," she said. Four people died overnight, a female in her 40s who had been in palliative care but was unvaccinated, a male in his 70s who was vaccinated, a male in his 80s who was unvaccinated and a female in her 70s with authorities yet to receive further details about her. There were 13 cases in the Hunter New England area. The Premier said while there were no cases in Armidale, health experts had advised to continue the lockdown in that area for a further week. In Western NSW there were 26 cases overnight and the Premier said it was likely the lockdown areas would be extended wider. Ms Berejiklian also flagged harsher punishments to be introduced from Monday, including increased fines for public health order breaches and enhanced random checkpoints at key roads. She said 500 extra Australian Defence Force personnel would also be deployed to help enforce the order. The 10 kilometre rule will also be reduced from Monday, with shopping, exercise and outdoor recreation to be done in a person's local government area or, if outside their LGA, within five kilometres of home. A permit system to enter regional NSW will also come into effect on Saturday, August 21. The state has reached 50 per cent of first vaccinations, Ms Berejiklian said.
