A man has died while surfing in big swell at a Sydney beach.
The 44-year-old man was unconscious when pulled from the waves at Collaroy Beach about 12:45pm on Monday.
Bystanders performed CPR until emergency services arrived to take him to Royal North Shore Hospital, where he later died.
A Bureau of Meteorology warning for hazardous surf, with waves up to five metres, is current for the Illawarra, Sydney and Hunter coasts.
Police are investigating, and a brief will be prepared for the coroner.
