I live in Perth and sharks are all over the news with the amount of attacks in the last year.
but it won't stop me going swimming at the beach, as there has never been a swimmer eaten at a patrolled beach during the day
Generally its:
Surfers around the corner from a seal colony
Surfers at beaches with names like "the graveyard", Shark Bay, etc
Snorkelers/Divers in remote locations
1 guy swimming for fitness at 6am on a murky day (this was the only one at a main beach )
another guy swimming 350m from shore, on the same beach where above swimmer was eaten

it's a risk you take entering the water, but just like looking before crossing the road you can make that risk minimal
