Leviathan, Wooden roller coaster at Sea World in Surfers Paradise, Australia

Leviathan is a wooden roller coaster located at Sea World in Surfers Paradise, taking riders through a series of twists, drops, and climbs along its timber-frame structure. The ride operates multiple trains that carry passengers through the layout at varying speeds.

Sea World announced Leviathan in May 2019 as part of the $50 million New Atlantis precinct, alongside the Vortex and Trident rides. It was Australia's first new wooden coaster since Bush Beast at Wonderland Sydney in 1985. Delayed by the COVID-19 pandemic, it opened on 2 December 2022.

The coaster sits in Sea World's New Atlantis precinct, whose theming was designed by the Australian company Earthstory. Three modelled Atlantic-themed statues stand within the precinct, and the queue and station carry the same maritime setting. The name comes from the biblical sea monster, matched to the Atlantis theme of the surrounding area.

The final car of each train features backward-facing seats, giving riders a different view of the track as they move through the circuit. This arrangement offers a contrasting experience compared to riding in the front sections.

The 155-metre chain that hauls each train to the top is longer than the ride is tall: the lift alone runs 155 metres against a 32-metre peak. The two 24-passenger Timberliner trains were built by Gravitykraft, a subsidiary of designer The Gravity Group, and the last row of each faces backwards.
