Entering a blue soundstage and setpiece from the film, guests find themselves at Sydney Harbour at sunset. Boarding a turtle shell, the attraction begins with guests diving under the sea, going outside and into a cave, leading into a dark ride portion.
Journeying with Nemo and Squirt through the Great Barrier Reef, past glowing fish and jellyfish forests and Bruce's sunken submarine home. Afterwards, the attraction shifts into a spinning, high-speed roller coaster experience representing the East Australian Current, eventually making its way back to Sydney and the station.
Note: The Whale and Gerald are technically characters and locations, as scenes in the film are set both inside and outside their bodies (with Marlin and Dory being trapped inside both of their mouths at one point).
