"On Sunday afternoon, a 12-year-old boy was bitten by a shark near Nielsen Park in Sydney's east while jumping off rocks with friends. The boy remained in hospital on Tuesday. On Monday morning, a shark bit a chunk out of an 11-year-old boy's surfboard. Later that evening at North Steyne, a male surfer was bitten and his injuries were said to be life-changing. Further north on the state's mid-north coast, a surfer escaped serious injury when he was bitten by a shark."
"All Sydney's northern beaches were closed and authorities said people should stay out of the water. Dr Amy Smoothey, a fisheries scientist and shark expert at the NSW Department of Primary Industries and Regional Development, has analysed images of the bites. She said bull sharks were responsible for all of them, as they have distinct broad and overlapping triangular cutting teeth in their upper jaw and more slender teeth in their lower jaw."
Four people were attacked by sharks in New South Wales over 48 hours, including three incidents at Sydney beaches that prompted closures and warnings to stay out of the water. Victims included 12- and 11-year-old boys and two adult surfers, one sustaining life-changing injuries and another escaping serious harm. Fisheries scientist Dr Amy Smoothey analysed images and attributed all bites to bull sharks, noting their distinctive upper and lower jaw teeth. The Australian shark incident database records 212 bull-shark bites (about 16% of incidents) and a quarter of fatal bites. Bull sharks can live up to 50 years, prefer temperatures above 19C, and seasonally migrate to and from Sydney.
