Person seriously injured after SA shark attack

Ambulance crews were rushing to the difficult-to-access beach, situated at the bottom of a large cliff.

The attack comes after a spate of serious shark bites in recent months, including the fatal attack of 55-year-old Tod Gendle at Granites Beach on the state's West Coast in October.

His was the second shark death this year after 46-year-old teacher Simon Baccanello disappeared without a trace in May while surfing at Walkers Rock Beach, about 365km west of Adelaide.
