NSW Ambulance paramedics were called to treat the man who got into trouble while spear fishing on Thursday afternoon.
Inspector Giles Buchanan said the man was found unconscious and pulled from the water before his friends attempted CPR.
“The Toll Ambulance Helicopter’s medical team landed on Bondi Beach, where they treated the man, along with NSW Ambulance intensive care and special operations paramedics,” Buchanan said.
“This was a very traumatic experience for this man’s friends and we commend their quick response in trying to assist their friend.”
The man was taken to St Vincent’s Hospital in a critical condition.
