What do you expect to hear from shark experts? Well, I propose to make such experiment and tie on of those experts to the buoy in the river for w day.
Experts could claim also that more people are eaten by jetskis on Gold coast then sharks. Which means you could now swim with full confidence at Broadwater. At least till shark will eat jetskier one day.
i don't wish a shark attack on anybody. But do you think people might stop cliff jumping at blackwall reach if they knew it was a bull shark nursery/ breeding ground?
