A 91-year-old Mollymook woman was found floating face down at the Bogey Hole in Mollymook at 11.15am on Wednesday.
Swimmers noticed the woman floating face-down in the popular swimming hole and brought her to shore where an off-duty lifeguard and a Sydney doctor commenced CPR.
Ambulance paramedics arrived and could not revive the woman.
Emergency services, including Ambulance, NSW Fire and Rescue and life guard attended the scene and the swimming hole was closed while investigations were carried out.
Australian Lifeguard Service south coast coordinator Ken Walsh told the Times the off duty lifeguard contacted personnel who were on patrol 100 metres away at South Mollymook Beach.
He said about 30 people were in the vicinity of the rock pool at the time.
There are no suspicious circumstances surrounding the swimmer’s death and a report will be prepared for the coroner.
Mr Walsh reminded swimmers to swim between the flags at Mollymook and Narrawallee beaches.
He said council’s weekday paid lifeguard services would continue at North Mollymook and South Narrawallee beaches until Wednesday January 27.
Weekday lifeguard patrols will continue at South Mollymook until the end of February, while volunteer life saver patrols will continue on weekends and public holidays until Anzac Day.
He said apart from Wednesday’s incident, there had been no other serious issues at local beaches in recent days.
