Beaches in Sydney's south-east have reopened today, in a sign that more social distancing restrictions could be eased.

New South Wales recorded just six new cases of coronavirus overnight – a sign the state could be getting a handle on the outbreak.

Beaches in Coogee, Maroubra and Clovelly are now open for select activities including sand jogging, walking, swimming and surfing.

They were closed by Randwick Council on March 28, to discourage large groups congregating at the beach.

Those who use the beach for exercise must maintain 1.5 metres between each other, while groups will be limited to two people each.

Sitting or sun-baking on the sand is still not permitted and authorities will continue to monitor beaches to ensure the public is obeying the rules.

Ocean rock pools in Randwick City will remain closed until further notice as they are subject to a public health order to close.

"Can we just ask members of the public to be thoughtful and considerate because if you do the right thing, the beach can stay open," NSW Premier Gladys Berejiklian said this morning.

"It's when people don't do the right thing that the beach will close down. We want everyone to enjoy our natural beauty, especially now it's great for mental health to get out and about.

"And I am encouraged to see families and individuals getting out there more and exercising, and enjoying the good weather we've had," Ms Berejiklian said.

Those within the Northern Beaches council area – including Dee Why, Avalon and Collaroy – were recently reopened for exercise purposes only after being shut in the lead-up to Easter.

But Sydney's iconic Bondi Beach remains closed by Waverley Council including Tamarama and Bronte beaches.

Last week NSW Health identified Randwick and Waverley as being known coronavirus cluster hotspots after a number of cases of community transmission where the source has not been identified.

Anyone experiencing mild symptoms of coronavirus in these areas, which stretch from Sydney's west to the city's north, are being urged to get themselves tested at one of several new COVID-19 clinics.

NSW has record just six new cases of COVID-19 overnight, bringing the state's total to 2963, with 249 currently being treated in hospitals.
