Gladys Berejiklian on Thursday said her government has been working with the industry on increasing patronage in restaurants and cafes in June and July.

"The government will have more to say in the very near future about what restaurants and cafes will look like in June and July," she told reporters in Sydney on Thursday.

Currently, dining venues can allow up to 10 patrons if they maintain social distancing, including alcohol table service with a meal at NSW pubs and clubs.

Increasing patronage in June would align with the easing of regional travel restrictions across the state and the opening of museums, galleries and libraries from June 1.

The premier has also flagged plans to allow international students back into NSW, potentially through the hotel quarantine system in place for Australians returning home.

This would help support regional towns and universities relying on the sector for economic activity and employment, she added.

"We have demonstrated our capacity to process people in quarantine," Ms Berejiklian said.

"It's opportune for us to consider when we can safely welcome back foreign students."

The premier noted this wouldn't be happening until after July and discussions are still underway with the federal government.

On Thursday the state reported two new COVID-19 cases from more than 9700 tests,

Three people are in intensive care.

One of the new cases was a student from Saint Ignatius' College in Riverview and another is a person who acquired the infection in Victoria.

The premier on Thursday also defended her calls for other states to re-open their borders, insisting it's in the best interests for Australia.

"This isn't personal," she said.

"This is about doing what we believe is in the best interest of our citizens."
