No need for a rumor, Because if there's gonna be anything new it will be the Waterpark.
it's been 4 years since any upgrades, and the parks on a 4 year cycle.
The new waterslide could be taking the place of the Awsome Aussie Twister or the Bondi pipeline
I heard one of the two was in need of bad repair . And the Flow riders at Pipeline Pradise are to be totally redone
next spring , Pumps ,Surface , and landscape.
