Fairfield Council will throw open the gates on Sunday for the final day of Aquatopia’s successful first season.
Nearly 40,000 have attended the multi-million dollar water park since it opened on December 10.
Entry will be free to Aquatopia on Sunday (April 23) once you have paid entry to the Prairiewood Leisure Centre.
The 10-metre giant water slide tower and multi-purpose adventure aqua tower have instantly become crowd favourites in the community.
Next season is already promising to bigger and better with the arrival of the new Stingray Surf Rider.
Aquatopia will open every day this week, up to and including Sunday from 10.30am to 5pm.
