Australia ranks high in global charts of shark attacks and is currently running an aggressive culling drive against the predators, but a new survey says Australians aren't that worried about them.

The survey of 583 visitors to Sydney's aquarium found 77 percent of the respondents were "not at all frightened" or only "moderately frightened" by sharks.

Some 87 percent of those polled said sharks shouldn't be killed despite their threat, while a sizable 69 percent see public education as the best method for preventing shark bites.
