NSW is inching towards a 90 per cent double does vaccination rate as restrictions ease and a new report suggests unvaccinated people are 10 times more likely to get infected.
The state recorded 222 new local COVID-19 cases from 66,680 tests and four deaths in the 24 hours to 8pm on Monday.
There are 254 people in hospital, with 42 in intensive care and 20 on ventilators.
An unvaccinated woman in her 90s has become the ninth death linked to an Albury aged care home.
A woman in her 80s who had received one vaccination dose also died as well as two unvaccinated men, one in his 80s and another in their 50s.
All three were from southwestern Sydney.
NSW's death toll stands at 604.
NSW Chief Health Officer Kerry Chant says "it's pleasing to see high rates of vaccination continue to inch upwards" as the state sets its sights on a 95 per cent full vaccination target, after it hits 90 per cent.
"Every skerrick of scientific evidence supports the role of vaccines in keeping people safe", she said, while reminding residents that they are not 100 per cent effective.
"You still need to get tested if you've got COVID symptoms and it is important that everyone continues to get tested," Dr Chant said.
A NSW Health report released on Tuesday shows intensive care admissions and deaths were lower among the fully vaccinated population during the peak of the state's Delta outbreak, which began in June.
There was a more than 10-fold difference between the rate of COVID-19 cases among the fully vaccinated and unvaccinated.
During the worst fortnight of the Delta outbreak, the case rate was 49.5 per 100,000 for the vaccinated, and 561 per 100,000 for the unvaccinated.
The report also found unvaccinated people were 16 times more likely to end up in intensive care or die.
The percentage of eligible people aged 16 and over with two vaccine doses is 89.9 per cent while 93.9 per cent have had at least one dose.
Premier Dominic Perrottet has said reaching 90 per cent full vaccination, which is tipped to happen on Tuesday, would be "momentous".
But unvaccinated NSW residents will have to wait until December 15 - or when the state reaches a 95 per cent double-vaccination - to enjoy greater freedoms.
Meanwhile, Sydney's eastern suburbs have three venues of concern where people potentially came into contact with a confirmed case and need to get tested immediately.
The Pacific Club Bondi is a transmission venue of concern after a positive case visited on Melbourne Cup day.
In addition to the City Gym at Darlinghurst, The Tea Gardens Hotel at Bondi Junction is also listed after cases were confirmed at the venue on October 20, 23 and 24.
And a group of people who attended a large funeral and wake in Sydney's west on the weekend are also being urged to get tested after several positive cases were linked to the events.
Cases are continuing to rise in Hunter New England local government, which recorded another 62 cases to 8pm on Monday.
Murrumbidgee had the second-most cases for a single district with 33.
