Six people were taken to hospital after a tourist bus flipped 20 meters down an embankment in the Gold Coast Hinterland last night.

Eighteen tourists and a bus driver had set out from O'Reilly's Rainforest Retreat on a glow worm tour.

When the driver stopped on the roadside to check a mechanical issue, the bus began rolling. The driver jumped back inside but was unable to stop it for careering off the road and down an embankment.

The driver was trapped for some time before being cut free by rescue crews. He and five others were taken to the Royal Brisbane and Women's Hospital in a stable condition.
