TANNUM Sands beach has been reopened after the sighting of a tiger shark earlier this afternoon.
A THREE-metre-long tiger shark was spotted by two 17-year-old lifeguards at Tannum Sands Beach this morning.
Mitchell Haigh and Riley Deakin told The Observer they were both near the flags when they first spotted the shark.
Paddling on his board in the water, Mitchell saw it first, but the shark was visible all the way from the beach too, where Deakin was standing.
The young lifeguards said the shark was "bigger than the board" and led to the evacuation of 18-20 people from the water.
They said all beachgoers seemed "reasonably calm" and did not appear to be too worried by the spotting.
A Surf Lifesaving Queensland spokesman said the beach will be closed for the next hour, at which time the situation would be reassessed.
He said the shark has not been spotted since the initial sighting, 30m-5m offshore between the flags, and suspected it was just swimming through.
