Police are searching for a man in waters off South Australia's Eyre Peninsula after the boat he was on capsized on Friday evening.
Police were notified just before 7:30pm that a boat with two men and two boys had overturned in the waters off Hall Bay between Coffin Bay and Elliston on the west coast.
One man and two boys managed to swim to shore, but a man in his 50s is still missing.
Local fishermen, State Emergency Service officers and STAR Group officers searched into the early hours of the morning.
A police helicopter conducted an air search with the use of night scan equipment, but were unable to find the man.
Officers from the Water Operations Unit have arrived in the area and are helping with the search.
