White sharks, by most scientific studies, have been shown not to be territorial.
CNN: Even after attacks on humans, sharks should be protected
Electronic tagging of 150 great white sharks found off the coast of central California revealed similar findings - the sharks gather in "hotspots".
Hammerhead sharks are also on the list and some people claim to have seen Great White sharks although it has never been proven.
Great white sharks are attracted to the warm ocean currents along Australia's southern coastline and are a constant concern for divers who work in the sea.
The observation takes account of new research that shows hammerhead and great white sharks patrol fixed routes in the ocean, gathering at hotspots to mate or feed.
Clinton Duffy, a shark expert with the Department of Conservation, said New Zealand is a hotspot for great white sharks, and other potentially lethal species also inhabit the waters.
So shark experts Neil Hammerschlag of the University of Miami in Florida, US, and Aiden Martin of the University of British Columbia in Vancouver, Canada, decided to study the predatory habits of great white sharks hunting off Seal Island, in False Bay, South Africa.
There is the best land based whale watching anywhere, and plenty of opportunities to get out on the water, including diving with Great White sharks, something people come from all around the world to do and can easily be done as a day activity in Cape Town (though cage diving remains controversial).
Strap on a mask and fins, and share the sea with schools of trumpet fish, black and white sergeant fish, small sharks and, of course, green turtles.
The fish cages stir occasional controversy, especially because they attract sharks, including feared white pointers up to 16 feet long.
Tiger sharks and the occasional great white and whale shark can be seen farther out to sea.
The main targets are Blue and Porbeagle sharks, a cousin of the notorious Great White shark.
He had also caught, off Long Island, some of the largest sharks ever landed: a 4, 500lb (2, 000kg) great white harpooned in 1964, and a 3, 400lb one, big as a Volkswagen, caught with rod and reel in 1986.
