POPULAR Sunrise weatherman Grant Denyer has passed out live on air during a stunt plane flight that pulled 8G.

The daredevil visited the Fraser Coast last week and spent time flyboarding at Aquavue Watersports and sightseeing on Fraser Island.

He told a spectator on Torquay beach that flyboarding was terrifying and exhilarating at the same time but during that activity he remained conscious.
