A swimmer is in hospital with serious leg injuries after surviving a shark attack off the South Australian coast.
The 64-year-old woman was swimming at Beachport in the state's southeast when she was bitten just before 8am on Monday, police say.
She was helped out of the water by other beachgoers who performed first aid until emergency crews arrived.
The woman, who has been identified as Pamela Cook by media outlets, suffered extensive injuries to her legs and was taken to Mount Gambier Hospital.
She was initially in a serious condition but she improved to be stable by Monday afternoon, SA Health confirmed.
Police closed the beach on Monday as State Emergency Service crews searched for the offending shark.
They were using a drone to scour waters about 800m off the coastline but were yet to locate the shark, a spokesman said.
It comes after a 46-year-old man was killed in a shark attack in May at Walkers Rock Beach, about 365km west of Adelaide.
