Two rescuers who went to help a man swept off rocks in Victoria’s southwest have died after their vessel flipped in the surf on the same day a father and daughter died in a boating accident in South Australia.

A man was taking photos from a rock ledge when he was swept out into the ocean at the mouth of the Sherbrook River at Port Campbell about 10.40am on Sunday.

“A rescue boat was deployed to assist the swimmer, which has flipped in the surf and thrown the three occupants into the water,” Victoria Police said.
