A man's body has been found in waters about 450 metres east of Sydney's Bondi Beach a week after a man went missing nearby.

NSW Police said the body was spotted just after 8am on Saturday and was retrieved by the Marine Area Command.

A report is being prepared for the coroner.

The body has not been identified and a forensic examination will be carried out to determine whether it is a man who went missing off Bondi Beach during wild weather earlier this week.

On Monday afternoon, emergency services were called to the southern end of the beach after receiving reports of a swimmer "in distress".

A low pressure system wreaked havoc along Australia's eastern coastline last weekend.

Two bodies were found in floodwaters in NSW and three people are known to have died in Tasmania.
