Ms O'Neill pulled herself to safety on a nearby wharf and members of the public ran to help herA woman has been taken to hospital with “serious” bite wounds to her leg after being mauled by a shark while swimming in Sydney Harbour. Shark attacks in Sydney Harbour are rare, but the area is known to be an important habitat for bull sharks and their young. Shark scientist Amy Smoothey said a “bull shark was likely responsible” following an analysis of the bite and images provided by authorities. Tagging indicates that bull shark numbers in the harbour were at their highest in the Australian summer months of January and February, Ms Smoothey said. It was Sydney’s first shark attack in the harbour since 2009, when an Australian navy diver was mauled by a bull shark during a training exercise in Woolloomooloo Bay.
