of Whirlpool Hot Springs for the Winter season. The current Buccaneer Bay opened in September 2005. Mach 5 was a large water slide complex, divided up amongst five different slides. The Sidewinders are two open flume slides which twist down to the bottom around the outside of the complex. The Jetstreams are three high speed body slides. The central slide is a freefall to the splashdown area below, similar to the Summit Plummet at Disney's Blizzard Beach. The outer two are similar, but traverse down the slope in a snake-like fashion. The Mach 5 was acquired second hand from a defunct waterpark in Brazil and opened at the park the first attraction in the Extreme H2O Zone in 2006. Following unsuccessful maintenance in December 2018, Mach 5 is now closed permanently. Mach 5 has been replaced by a new slide grouping consisting of Kaboom!, Double Barrel and Super Ripper. Double Screamer was originally named Rampage, the Double Screamer was the first all fibreglass slide in the world. It was closed and removed in 2005 due to safety concerns on similar rides overseas where riders suffered serious injuries. It was also removed to make way for an expanded Buccaneer Bay which now stands in its place. Mammoth Plunge was built in 2000, the Mammoth Plunge Slide was donated to Sea World in 2005 where it now operates. It was replaced with a mirror of the adjacent Mammoth River slide. Speedcoaster saw guests plummet down an enclosed snake-like drop before a steep freefall to the splashdown zone. Originally named 'Speed Slide' when the park first opened, the attraction has since been refurbished and modified. This ride was closed to make way for the addition of AquaLoop in 2010. This ride was moved to Big Splash in Canberra. Speed Slide was a pair of high speed body slides that existed where the Speedcoaster once stood, and where the AquaLoop now stands. The slides were also home to a stunt show which saw performers ride the slide standing up and on boards. Terror Canyon 1 & 2 was closed down in 2008 pending demolition, extended maintenance or re-development. In 2009, the park confirmed that the Terror Canyon location could be used for future attractions. In 2010, the rides were removed from the park map with the queue and station being used for the zip lines. Twister was an attraction featuring two body slides. These
