The Sydney shark attack that killed Nico Antic was one of four recorded in the span of two days.

Officials are taking drastic action after three people, including an 11-year-old and a 13-year-old, were attacked by sharks at a popular vacation destination.

Two surfers attacked on the same day in Sydney, Australia.

A surfer was bitten by a shark in waters off Sydney on Monday evening, the second person to suffer critical injuries in a shark attack near the Australia's largest city in little more than 24 hours.

I felt him shaking my leg. I thought I couldn’t put my hand out because he might rip it off,” the victim said.
