Sandboarding at a popular dune at Shipwreck Bay came to a sudden halt after a high-speed accident prompted a call to the rescue helicopter service yesterday.
A 30-year-old man was airlifted to hospital with suspected back injuries after flying down the renowned dune and crashing at the bottom just after midday.
Fellow sandboarder Tom Van Der Leden was halfway up the dune, at what locals call Mookies 2, when he saw the man appear at the top, laughing and waving.
"Next minute he came flying over the hill, head-first, really fast. Everyone thought he was going to stop but he hit the grass and bounced twice. He was flying and he flew a long way," Mr Van Der Leden said. "Everyone laughed and then stopped when they realised. He was obviously very winded and was groaning. Then he asked for help."
Another witness said the man had hit cars parked at the bottom of the dune but it was unclear whether this was true.
The man was taken by helicopter to be X-rayed for suspected broken vertebrae. News of his condition was not available.
