A 29-year-old woman has fatally drowned at Venus Bay this evening, Wednesday, January 13.
It is believed the woman, from Rowville, was among a group of people who went to the assistance of a teenage girl who was seen struggling in the water at around 7.30pm.
While the teenage girl and other swimmers made it to shore safely, the woman in her 20s was pulled from the water by an off-duty member of Life Saving Victoria.
CPR was performed but she could not be revived.
Police said investigations were continuing and a report would be prepared for the Coroner.
