Sea Viper, Steel roller coaster at Sea World, Gold Coast, Australia

Sea Viper was a steel roller coaster at Sea World on the Gold Coast featuring orange track supported by white structures. The ride stretched across about 600 meters and included three inversions that took riders through multiple twists and turns.

Sea World opened the ride as Corkscrew on 17 September 1982, its second roller coaster after Thrillseeker and the first in Australia with three inversions; park attendance rose 20% in its first year. In 2005 Kumbak was engaged to develop a new train, and during 2009 the track was repainted from white to orange. It closed in November 2009 for the Arrow Dynamics train to be replaced by a low-profile KumbaK model, reopening as Sea Viper, then shut in early 2014 and was confirmed permanently closed on 17 July 2014.

The Corkscrew, as it was first called, was Australia's first roller coaster with three inversions and only Sea World's second coaster, after Thrillseeker. Park attendance rose about 20% in the year after it opened. In 2009 the track was repainted from white to orange and a new low-profile train from KumbaK replaced the original Arrow Dynamics train.

The queue led under the first 180-degree right turn before riders boarded at the station beneath the Sea Viper figurehead. A chain lift raised the train to 28 metres, then the track dropped to near ground level into a vertical loop and the double corkscrews. The second corkscrew passed directly under the Sea World Monorail System.

The second corkscrew passed directly beneath Sea World's Monorail System, then curved up and back over it, so riders crossed the monorail line twice in a few seconds. The ride's final brake run slowed the train before it returned to the station.
