So as Minister of Conservation, I want to protect both sharks and people. I think the most simple and effective way to do this—to manage the risks to public safety and to protect the sharks—is to prohibit shark cage diving, except potentially in defined areas. Because shark cage diving does interfere with the sharks' natural behaviour. As Ms Dowie noted, operators put berley or bait in the water to attract the sharks. Australian researchers have noticed that there are detectable changes in the behaviour of great white sharks where there's shark cage diving. They tend to spend more time at the surface and more time at the dive site than they would otherwise.
