Police are preparing a report for the State Coroner following a death of a man at Port Noarlunga.

Just after 1.30pm today, Thursday 27 February, police and emergency services were called to the Esplanade near the jetty after a 64-year-old man was pulled out of the water.

Police believe the man was diving at the time and may have suffered a medical episode.

Paramedics worked desperately to revive the man but sadly he died at the scene.

There are no suspicious circumstances.
