An unvaccinated woman in her 80s at the Wyoming Nursing Home in Summer Hill has also died, taking the toll for the current outbreak to at least 28.
Greater Sydney and surrounding regions are in lockdown until at least August 28 as health authorities battle to contain a outbreak of the virulent Delta strain.
The NSW Hunter and the Armidale region are also enduring snap week-long lockdowns.
Premier Gladys Berejiklian said 12 suburbs in the Penrith local government area would be added to the "areas of concern" list, prompting harsher restrictions for local residents.
However the Georges River council area may soon be taken off the list.
"As we have seen in the last few days, the numbers are bouncing around a bit but clearly we need to reduce those numbers," Ms Berejiklian said.
"I urge everybody to please stick to the rules, the health advice, and only leave home if you absolutely have to."
There are 58 patients in NSW in intensive care, with 24 ventilated.
Meanwhile, hundreds of young adults in Sydney have waited hours to receive an AstraZeneca jab as the outbreak shows no signs of abating. As Health Minister Brad Hazzard on Saturday urged all residents to "stay home and get vaccinated", hundreds flocked to a walk-in vaccine clinic requiring no GP referral in Glebe.
NSW Health brought on eight extra vaccinators throughout the day to help shorten a queue running more than 100 metres. The centre vaccinated almost 1000 people over the three days it was open.
More than 100 people were still waiting in line when it was scheduled to close at 4pm. They all received their jab, according to the Sydney Local Health District. The centre was one of five walk-in locations open on Saturday across Sydney's inner west, west and southwest.
About 45 per cent of NSW residents over 16 have been vaccinated against COVID-19 at least once, up from 40.95 per cent a week ago.
