In total, 24 new cases have been linked to the Western NSW Local Health District to 8pm on Sunday night.

One of those cases is in Orange, while 14 were in Dubbo, six in Goodooga and one each in Parkes, Mudgee and the Coonamble region.

The new case is in addition to the six confirmed on Sunday, with those six cases contractors from Sydney who have been working in the city, it was confirmed on Monday by Member for Orange Phil Donato.

A list of exposure sites has been identified across Orange. There's six different sites in total.

NSW deputy premier John Barilaro confirmed the numbers on Monday morning, and urged residents in Orange and across the Western NSW LHD to come forward for testing and vaccination.

He, along with the state deputy chief health officer Dr Marianne Gale, said there was real concern in areas like Orange, Bathurst, Parkes, Lithgow and Cobar, where there's been detections of virus fragments in sewage systems.

"Don't get caught up in the brand debate, book in for a vaccination. They're great vaccinations, safe vaccinations," Mr Barilaro said.

Elsewhere across NSW, NSW Premier Gladys Berejiklian urged people to turn away from case numbers in favour of watching vaccination rates.

"Once we get to 80 per cent double dose, essentially we will have normalised COVID the way we treat other conditions," she said.

Ms Berejiklian said the outbreak had been an early forced transition to living with the virus.

"Every state is going to have to live with COVID," Ms Berejiklian said.

She said there would be "more to say" about a return to schools later this week given how close the 6 million vaccinations target had come.

Ms Berejiklian said western NSW remained the main area of concern outside Sydney's 12 local government areas, and that 738,000 people were vaccinated in NSW during the past week.

"We're up to 5.9 million jabs in NSW," Ms Berejiklian said.

"I'm so pleased everybody has really heard the call."

Federal Health Minister Greg Hunt told reporters in Canberra on Monday that vaccination rates in recent weeks had begun to match records around the world.

More than 139,000 people were vaccinated nationally on Sunday.

"All of those numbers are progressively increasing," he said.

"Supply is strong, distribution is strong and the uptake is incredible."

Monday delivered tighter NSW lockdown rules, including for the Hunter. Masks are now mandatory outdoors in the region until August 28, the mooted expiry of the statewide lockdown.

Curfews have now come into force across Sydney's 12 local government areas of concern, with that city's lockdown not due to expire until the end of September at the earliest.
