The water park layout was set to include water slides, sprinkler playgrounds and pools.
A boardwalk promenade would link the water park section to the rest of the site and attractions.
The centrepiece of the second stage was the Endless Surf wave pool to be delivered by WhiteWater.
Plans have been lodged for the second stage of a major waterpark and tourism facility on Steve Irwin Way, Glenview.
The wave pool, proposed to be of the same scale as pools being delivered for the Paris and Tokyo Olympics, would include a swim-up pool bar, spectator/judging stand and other facilities.
