Pubs, clubs, cafes and restaurants will be able to have up to 50 customers, subject to conditions, from June 1.
The venues will need to apply the one person per four square metre rule, and patrons will have to observe social distancing.
Premier Gladys Berejiklian went beyond expectations when announcing the further easing of restrictions on Friday.
Ms Berejiklian said patrons will have to be seated.
"There is no mingling, no standing around. You have to be seated as a table, even if it's at a pub," she said.
"We know this is a big step. But the rules and regulations will be very strict, to make sure safety is paramount."
Ms Berejiklian said the move was about safely bringing back thousands of jobs.
"This decision has been made with expert health advice and both businesses and patrons will be subject to strict rules and guidelines," Ms Berejiklian said.
"All customers must be seated and no bookings of more than 10 allowed, in addition to many other conditions which must be met."
The government has been working with the AHA and ClubsNSW on the changes.
Deputy Premier John Barilaro said, "This is a game-changer right now, as we continue to deal with the aftermath of the devastating bushfires, continued drought and COVID-19, it's important for people to find a way to enjoy themselves and take a break from the daily pressures they are facing,".
"A morale boost and the additional economic stimulus provided by pubs and clubs is what our communities need and I look forward to enjoying a beer in the bush with locals very soon."
Treasurer Dominic Perrottet said the government was moving to swiftly and safely get businesses back in business and people back to work.
"There are about 280,000 people employed in this sector of the economy and allowing venues to safely cater for more customers will provide another boost to business and jobs," Mr Perrottet said.
"NSW is opening back up for business, and as we ease restrictions everybody needs to follow the health and safety guidelines, to ensure we make it a success and can continue."
