A man has been missing for more than 15 hours after he tried to rescue a fisherman who was swept off a Gold Coast beach.
The 35-year-old was swept into the water at Miami Beach after trying to help a fisherman who was knocked over by a wave about 6pm on Thursday, Queensland Police said.
It was still half an hour off sunset and almost an hour from last light when the man went missing, but an extensive search failed to find him before dark.
Police in all-terrain vehicles are patrolling the shoreline on Friday while water police vessels search the sea.
