A British expat who was mauled to death by a 15ft great white shark may have been targeted due to an unusual swimming habit he had, according to experts.
Diving instructor Simon Nellist was attacked on Wednesday afternoon in waters off the coast of Little Bay, Sydney, while training for a charity swimming event.
The 35-year-old RAF veteran, from Penzance, West Cornwall, was the Australian city's first fatal shark attack victim since 1963, with all of its beaches then temporarily closed.
