The teenager suffered puncture wounds to his hand and went home before calling paramedics who took him to hospital. “A teenage boy was treated for injuries to his hand and taken to Gosford hospital,” the spokesperson said. Gosford hospital on Wednesday afternoon said the teenager had been discharged. The NSW Department of Primary Industries said shark biologists had determined a great white was likely responsible. “NSW DPI shark biologists have assessed photographs of the teenager’s injuries and surfboard and have determined the bite indentations are indicative of a white shark,” a spokesperson said. DPI Smart drumlines were set at Avoca and North Avoca shortly after 7am on Wednesday as per normal practice, but no sharks had been caught, the spokesperson said. Surf Life Saving NSW used a drone to survey the area on Wednesday afternoon.
