Bull Shark Bites Swimmer in Brisbane River

A bull shark attack in the freshwater Brisbane River, a rare inland/river setting, with corroborating context from an ongoing University of Queensland bull shark research programme documenting the species' established presence in that waterway.

On Saturday, February 26, 2005, an 18-year-old male swimmer from East Ipswich experienced an unexpected encounter with a bull shark while swimming with a friend near the boat ramp at Karalee in the Brisbane River, Queensland, Australia. The incident occurred when the swimmer and his companion Wade were casually swimming near the boat jetty. The teenager was stung by a wasp and instinctively ducked his head underwater to relieve the sting. What happened next was startling: a bull shark approximately 1.5 meters in length bit him on the head. Initially disoriented and submerged, the swimmer believed his friend was playing a prank until he felt the shark shaking him. In his effort to push the shark away, the teen's left index finger entered the animal's mouth, resulting in a bite to that finger as well. He successfully fended off the shark, which disengaged from the encounter. The injuries sustained were minor, consisting of bites to the head and finger. The swimmer was surprised by the incident, noting that he had not been aware that sharks inhabited the Brisbane River. The involvement of a bull shark was significant from a scientific perspective. University of Queensland professor Craig Franklin, who had been studying bull shark populations in the Brisbane River for four years, confirmed that bull sharks of this size were present in the river system. Franklin and PhD student Richard Pillans had previously captured bull sharks up to 1.5 meters in length during their research, making this unprovoked encounter a notable documented incident of human-shark interaction in an urban river environment.
