Police divers have made a tragic discovery while searching for a missing swimmer at the Royal National Park.
The body of the 20-year-old man has been found in water at Watamolla Beach, near where he was last seen swimming with friends on Tuesday night.
With a report being prepared for the coroner, Surf Life Saving CEO Steve Pearce told the Triple M Newsroom police are still conducting their investigations.
"We're unsure of the background [of the incident] at the moment, but what it does really reinforce is the dangers of swimming at an un-patrolled location," he said.
"The Watamolla area is an extremely dangerous place to swim, that lagoon has claimed countless lives already.
"We're asking people, please, if you're going swimming to escape this humidity and this heat, please find a patrolled location where there's lifeguards and lifesavers on duty."
