Blue Lagoon was a themed water park at Dreamworld on the Gold Coast, Queensland.

[1] Blue Lagoon served as Dreamworld's water park until 2006 when the area was closed months before the opening of WhiteWater World.

Blue Lagoon opened with three water slides: Aqualoop Flume, Krakatoa's Revenge and Toboggan.

[5] In 2006, construction for the new water park began and Blue Lagoon would be closed to the public later that year, months before the opening of WhiteWater World.

During the 2010s, most of Dreamworld's derelict buildings and attractions were demolished such as Eureka Mountain Mine Ride and the Sky Link Chairlift.
