Beaches in Sydney's south-east will reopen from tomorrow for people exercising in a slight easing of social distancing restrictions.

From Monday, Coogee, Maroubra and Clovelly beaches will be available 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 will not be permitted.

Randwick Council closed Coogee Beach on March 28 after people ignored social distancing rules. It will reopen for exercise only from Monday April 20.

"We appreciate that with the current restrictions in place people are increasingly looking for access to more open spaces including water for their physical and mental well-being," explained Mayor Danny Said.

"I need to stress that our beaches are not open to general use and can only be accessed for exercise. Activities such as sitting on the sand, sun-baking or gathering in groups will not be permitted and Council staff and police will be enforcing these restrictions."

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

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 21 new cases of COVID-19 overnight, bringing the state's total to 2936.
