Shark bites are not that common - all of SA had about 248 shark bites in 117 years. This is about 10-15 km west of Cape Town i.e. the Atlantic side. Sharks prefer the Indian Ocean to the east because of the warmer water. In any event with millions of people visiting thousands of locations and only 248 attacks in 117 years your chances of a shark attack is lower than the chance most investors have to recover all their investments in FTX :D
