Caps on indoor and outdoor gatherings, weddings and funerals will be revised upwards from Monday as part of NSW's revised roadmap out of COVID-19 restrictions.
It comes as NSW records 587 new locally acquired COVID-19 cases in the 24 hours to 8pm on Wednesday.
NSW Premier Dominic Perrottet met with the crisis cabinet late on Wednesday to tweak the roadmap as the state prepares to emerge from months of lockdown on Monday.
The state on Wednesday reached the 70 per cent double-dose vaccination milestone.
As part of the new plans, indoor gatherings will from Monday be capped at 10 people, not counting children aged under 12. Outdoor gatherings will now be lifted to 30 people.
For weddings and funerals, 100 people can attend.
NSW indoor swimming pools will also be able to open for swimming lessons, training and rehabilitation activities.
From the 80 per cent vaccination milestone, expected around October 25, restrictions will ease further.
This includes a cap of 3000 people for controlled and ticketed outdoor events and the reopening of nightclubs.
Mandatory mask use will also be ditched in office buildings in an attempt to encourage workers back to the Sydney CBD.
These freedoms will only be restored for the fully vaccinated until December 1, when freedoms are restored for the unvaccinated.
Meanwhile, all school students will return to on-site learning by October 25, a week sooner than the prior plan. Kindergarten, Year One and Year 12 students return on October 18.
"We have always said that vaccination is the key to our freedom and the sacrifices and the effort of people right across NSW have ensured that we can open up as quickly and safely as possible," Mr Perrottet told reporters on Thursday.
"This is not just a health crisis, it's an economic crisis too."
Greater Sydney will emerge from 15 weeks of lockdown on Monday when gyms, cafes, restaurants, shops, hairdressers and beauticians will reopen and people will be allowed to venture more than five kilometres from home.
Mr Perrottet said he would be calling other premiers on Thursday with Queensland Premier Annastacia Palaszczuk a priority.
NSW reached its 70 per cent COVID-19 vaccination target on Wednesday during Mr Perrottet's first full day as premier and after new deputy premier Paul Toole was sworn in.
But NSW Labor says it is fielding questions from businesses owners who are confused about their responsibilities.
Meanwhile, lockdown will be extended until Monday for a number of areas in regional NSW including Oberon, Snowy Monaro and Menindee and Sunset Strip in the Central Darling Shire.
