Two more people have died from COVID-19 in NSW, taking the toll from the state's latest outbreak to 10.
NSW Health confirmed a woman in her 80s had died at her home in Pendle Hill, in Sydney's west, on Monday afternoon, while a man in his 80s died while being treated at Campbelltown Hospital.
It brings the state's death toll since the start of the pandemic to 66 and comes a day after a Sydney-based Brazilian student in her 30s became the youngest woman to die of COVID-19 in Australia.
NSW recorded 145 new local COVID-19 cases in the 24 hours to 8pm on Sunday, of which 51 were in the community for the entirety of their infectious period and 25 were in the community for part of their infectious period.
The NSW crisis cabinet met on Monday to devise a strategy to deal with the evolving crisis and to begin workshopping the restrictions to remain in place in Sydney over the coming months.
Greater Sydney's lockdown is due to end on Friday, though Premier Gladys Berejiklian flagged some restrictions may be tightened and others eased where transmission risk is minimal.
This may involve tightened or more targeted measures in virus-hit southwest and west Sydney, as well as changes to testing requirements.
However, some restrictions would remain until the majority of the NSW population was vaccinated, regardless of daily infection numbers.
The future of homeschooling is yet to be determined but construction activity, currently paused, will resume in some form from Saturday.
"We might need to go harder in some areas and release some settings in others," Ms Berejiklian told reporters.
"Our mission is to allow our citizens to live as safely and as freely as possible."
Chief Health Officer Kerry Chant said Greater Sydney's success rested on three factors - compliance with a tight lockdown, increased vaccination rates and the support and patience of the community.
She reiterated stronger lockdown measures would have marginal impact given the prevalence of transmission among critical workers who cannot stay home.
"The people of southwestern Sydney and western Sydney are the people that keep our city running. They do a lot of the work in distribution centres, food, logistics, transport," Dr Chant said.
"We should all reflect on that."
Dr Chant also indicated the NSW government would on Tuesday enable all people to walk up and receive the AstraZeneca vaccine at some locations.
She echoed updated expert immunisation advice that locked-down residents should "strongly consider" taking the AstraZeneca jab.
While Pfizer supplies remain constrained, the NSW government says it has plentiful AstraZeneca, which is effective in preventing hospitalisation or death.
Dr Chant also suggested NSW Health could administer more than 350,000 vaccines per week if its Pfizer supply was enhanced. This is separate from the federal government's vaccine rollout.
"We have to make really hard choices and what we're doing is looking at the best evidence (on) available supply," Dr Chant said.
"Ultimately, if we had more vaccine, we could do more ... but we do have a good vaccine, which is AstraZeneca."
It was later revealed frontline supermarket workers in five virus-affected western Sydney council areas would be eligible for priority Pfizer vaccination.
There are currently 44 COVID-19 patients in NSW in intensive care, of which 18 are ventilated.
The fate of three local government areas in regional NSW areas due to exit a lockdown on July 28 is also unclear.
Frustration over lockdowns boiled over on Saturday when about 3000 people marched through Sydney's CBD in protest. Some 57 people have been charged to date.
Police Commissioner Mick Fuller said on Monday he was aware of online talk about another protest on Saturday, and emphasised any attendees would be arrested.
