Following a tragic fatal shark attack in Perth’s Swan River over the weekend, Marine Biologist Rob Harcourt spoke with Chris O’Keefe on ways Aussies can stay safe this Summer.

Several Australian beaches have been closed in recent weeks due to shark sightings and encounters.

Mr Harcourt reveals sharks tend to move around a lot during rainfall conditions. Bream fish and kingfish move similarly, making it likely that sharks are anticipating where the fish are going to be, therefore ending up in river streams.

A take-home message for people is “if you do see groups of dolphins feeding, it’s entirely plausible that there’s going to be sharks feeding on those same fish as well,” Rob Harcourt said.

“Don’t rush to jump in with them.”
