The Telegraph reports
that three fishermen set out from Leeman, 170 miles (270 km) north of Perth, on Thursday but failed to return. That sparked an expansive search effort in which 125 square miles (320 s/km) of ocean were scoured.
It was a Channel 7 helicopter that first spotted one of them men and relayed his location to rescue boats. "When we first spotted him, one of the scariest things was there was a massive hammerhead shark
not 20 meters away from him, just slowly circling around him," Channel 7 reporter Grant Taylor told Australian radio.
"He's stark naked... just struggling to swim and float on his back and try and keep his head out of the water," Taylor added. "He keeps waving at our chopper trying to get us to come down and help him but there's nothing we can actually do."
The helicopter crew dropped an inflatable rescue raft, but it drifted far away from the stranded man.
The man can be seen with his hands clasped in prayer, calling out for help in the video as the shark circles nearby.
Soon thereafter, a rescue boat arrives and snatches him out of the water. A second man was later found but he died shortly after being rescued. A third fisherman remains missing.
"We haven't spoken to the survivor yet and until then we don't know what happened," a Western Australia Police spokesman told reporters.
