The girl was surfing with her father when she was attacked off Esperance in Western Australia state on Monday afternoon, a police statement said.

She was taken in critical condition to Esperance Hospital, where she died. Police have not said what type of shark was responsible.

Australia has averaged fewer than two deadly shark attacks per year in recent decades.
