A beachgoer has revealed the final time he saw a man before he vanished off a popular beach as the search to find him resumes.

A man was “laughing” with his friends moments before he vanished off a popular beach in Sydney’s east, a beachgoer has revealed.

The search for the man, who failed to return to shore at Maroubra Beach on Sunday, has resumed.

Emergency services were called about 4pm on Sunday following reports a man swimming at the southern end of Maroubra Beach had not returned to the shore.

The man in his 30s was with several friends at the time, police say.

Crews from the Marine Area Command, Surf Life Saving, Randwick Council, and Toll and Westpac helicopters looked for the man until 6pm before the search was suspended.

The search for the man resumed at 8am on Monday.

“A friend of theirs came along who was also looking for sea urchins … he was laughing,” Mr Wood told NewsWire.

Mr Wood said the man had been on the rocks looking for sea urchins with his friends.

The man’s friends had no idea he was missing at first, Mr Wood said.

“They did not think at all that their mate had gone missing,” he Wood said.

Mr Wood said the swell was about half a metre, describing the incident as “sad”.
