Emergency Services were called to Coledale Beach late yesterday afternoon after a teenager was reported struggling in rough conditions while a hazardous surf warning was in place.
Off-duty Thirroul lifesaver Kyle Mathiesen came to the rescue after being alerted by members of the public and screams for help around 4.45pm.
Surf Lifesaving Illawarra said Kyle quickly assessed the surf conditions before stripping down to his board shorts, grabbing a board and swim fins and paddling out to the swimmer.
The teenager was clinging to a board with no fins, only metres from rocks when Kyle reached him.
He then returned the teen safely to shore.
