The downward turn comes just one day after Professor Paul Kelly, the government's Chief Medical Officer, said there were "signs of hope" the latest Omicron outbreak had reached its peak in NSW.

On Sunday, NSW Health reported 571 new cases of the virus within the Murrumbidgee Local Health District (MLHD), a big decrease from yesterday's tally of 839.

A total of 34,660 new cases were recorded across New South Wales overnight, once again significantly lower than yesterday's 48,768.

Exactly 20 deaths were recorded across the state for the second day running.

Of the new cases reported on Saturday more than 16,000 were self-reported rapid antigen tests and just under 21,000 were PCR tests.

There are 2650 patients in NSW hospitals, slightly up on the 2576 reported on Friday. Of them, 191 are in intensive care.

The state is 93.8 per cent double dosed for eligible residents 16 or over.

More than 25 per cent have also had a booster, while 11.5 per cent of children aged five to 11 have received their first jab.

More than 200 people have now died to coronavirus in NSW during the past week, but Mr Kelly said there were positive signs for the weeks ahead.

"All predictions and now the actual forecasting based on actual numbers of cases, particularly in NSW but also in Victoria and ACT, leads me to believe that we are close to the peak of this wave in terms of cases," he said, noting infections are likely to be going under-reported.

NSW Health continues to urge anyone who is eligible to book in for a vaccine booster.

"People aged 18 years and over are eligible for a booster if they had their second dose at least four months ago," the department said.

"We urge people to get their booster dose as soon as they are eligible, to best protect themselves, their loved ones and the community from the ongoing transmission of COVID-19. We also strongly recommend that people aged 12 years and over who are severely immunocompromised have a third primary dose of vaccine from two months after their second dose."

The federal government's online vaccine clinic finder can be used to locate a clinic and book a jab.
