“It breaks our hearts to have three tragic drownings in one day; three families who will never be the same again,” Treloar said on Twitter.
The teenager was seen struggling in the water around 7:30 pm when several people came to help her, including the woman, who was later pulled out of the water by an off-duty lifeguard after she “got into trouble,” the Victoria police in a statement.
The woman received cardiopulmonary resuscitation but died at the scene.
“A report will be prepared for the coroner and the investigation into the circumstances surrounding the incident is ongoing,” police said.
Two dead 20 kilometers apart on the Mornington Peninsula
It came shortly after emergency services were called to Bushrangers Bay in Flinders, some 20 kilometers further south, after people were washed away by rocks and found in danger in the ocean.
Four people are believed to have been dragged off the rocks around 3:30 pm, police said. Two members of the public entered the water to help.
A woman died at the scene. The other five were rescued and taken to hospital. Its status is unknown.
Four helicopters were dispatched to the scene, including two life-saving helicopters and a police air wing that scoured the ocean for signs of people.
A large contingent of police cars and ambulances were in Bushrangers Bay this afternoon.
A report on both drownings will be prepared for the coroner.
There were other incidents on Wednesday.
A boy is in critical condition after being rescued from Lysterfield Lake in Narrewarren, 38 kilometers southeast of Melbourne, in the afternoon.
A young woman was resurrected after being pulled out of the water in Port Phillip Bay, on the eastern north side of the Mornington Peninsula.
Treloar said the lifeguards would return to duty today, but asked the public to play their part.
“We are committed to reducing drownings, and our team will be back tomorrow, but we need them to do their part,” he said.
“Don’t drink and drown, learn to identify a break, talk to first responders, and if you’re not sure, swim between the flags.”
