NSW is reporting 1290 new cases and four deaths.
The majority – 80 per cent – of new cases were in western Sydney.
NSW Premier Gladys Berejiklian says western NSW remains a concern, but cases are stabilising across regional NSW.
Nearly two-thirds of NSW has had at least one dose of a coronavirus vaccine.
“While it is important for us to reduce case numbers, we know the greatest way to do that is getting vaccinated,” Berejiklian says.
“Vaccination is the key in terms of our freedom and reducing the spread of the virus.“
“The other number critical is the rate of hospitalisation.”
There are 840 people in hospital in NSW with COVID-19 (a rise of 3 per cent on the day before), including 137 in intensive care (a rise of 8 per cent), of which 47 are on ventilators.
For comparison, there were 813 people in hospital on Sunday and 778 on Saturday and 126 in intensive care on Sunday and 54 on ventilators.
Of the four deaths reported overnight, one was a man in his 50s who died at Dubbo Hospital. He had underlying health problems.
Two were men in their 70s. One of them had been infected at an aged care home.
The fourth was a woman in her 60s who was infected at hospital.
“We are seeing such a high case rate,” NSW Chief Health Officer Dr Kerry Chant says.
“I cannot urge you enough to come forward for testing but importantly be very careful in the way you move about in your community.”
