Three new cases were recorded in Orange to 8pm on Wednesday night, taking our official tally of active cases in the community to 15, although six of those cases were escorted back to Western Sydney each with $1000 fines this week, where they'll remain in isolation.

Across the Western NSW Local Health District, a total of 35 cases were recorded - 25 in Dubbo, two in Bathurst, two in Bourke and one each in Forbes, Mudgee and Parkes.

NSW deputy premier John Barilaro said the situation across regional NSW was "a tinder box ready to explode".

"We are on a knife edge in the regions," Mr Barilaro said.

"We have areas of concern ... but there's sewage surveillance showing fragments of the virus where we have no known cases."

He said the decision to continue the lockdown in regional NSW was to protect communities.

"We're sorry to have to do this to areas where there are no cases, but the reason you may not have cases is due to the restrictions and minimising movement," he said.

"Stay united, and work to those restrictions."

The Sydney local government areas comprise 80 per cent of cases, Ms Berejiklian said, and urged people in those areas to adhere to the health advice.

"As far as western NSW is concerned we have seen obviously the concern level there continue ... however there has been a stabilisation of cases across the regions with the exception of western NSW."

Ms Berejiklian said the government would offer its schools plan on Friday, but from September 13 that local government areas of concern in Sydney would be offered an hour of recreation on top of their hour of exercise - if they were vaccinated.

"A family will be able to go out and sit in the park, as long as the adults are vaccinated," Ms Berejiklian said.

Outside those areas, five people can gather outdoors as long as all adults are vaccinated.

"That five can include children, but as long as it's adults all of them will need to be vaccinated," Ms Berejiklian said.

"We know that people coming together is what people miss the most."

NSw recorded 1029 cases in NSW, with three deaths, including a man in his 30s, in the 24 hours to 8pm on Wednesday.

"Unfortunately all three were unvaccinated," Ms Berejiklian said.
