Victoria is home to some of the highest-rated water parks in Australia, with options ranging from world-record-breaking thrill rides to massive indoor complexes that operate year-round.
1. Top Pick for Thrills: Adventure Park (Geelong)
Located just outside Geelong, this is Victoria’s largest water theme park and currently holds the crown for the most intense slides in the state.
- The Big New Addition (2025): Thunder Falls – Opened in November 2025, these are Victoria’s first free-fall drop slides. You stand in a translucent launch chamber before the floor drops out, plunging you 25 meters down.
- The Heavy Hitters:
- The Tsunami: A massive triple-funnel slide (the only one of its kind in the state).
- The Tornado: A 7.5-story drop into a giant funnel where you experience moments of zero gravity.
- Best For: Adrenaline junkies and families who want a full day out.
2. Best All-Rounders: Gumbuya World & Funfields
If you want more than just slides (like rollercoasters and wildlife), these two parks are the best choices near Melbourne.
Gumbuya World (Tynong)
- Key Slides: The Boomerango (a near-vertical wall climb) and the Taipan (a high-speed slide in total darkness).
- Highlight: It features a massive 300-meter Lazy River and the “Surf’s Up” wave simulator.
Funfields (Whittlesea)
- Key Slides: The Typhoon (a world-record-breaking “cannonball” slide) and the Kraken Racer, where you can race up to five other people.
- Highlight: The Blackout slide provides a disorienting, pitch-black experience that is a fan favorite.
3. Best Indoor & Year-Round Options
For those rainy Melbourne days or winter trips, these indoor aquatic centers offer massive slides that are often heated.
| Location | Top Slides | Why Go? |
| WaterMarc (Greensborough) | Tantrum Alley & The Pipeline | Often cited as the biggest indoor slides in the Southern Hemisphere. |
| Splash Aqua Park (Craigieburn) | Two massive loop slides | High-tech facility with great kids’ “Aqua Play” zones. |
| Leisurelink (Geelong) | Space Bowl & Black Hole | Features a “Space Bowl” that spins you around before dropping you into a pool. |
4. Regional Gems
If you are traveling through Northern Victoria, these council-run parks offer great value:
- Aquamoves (Shepparton): Features a “Rapid River,” a large indoor slide, and an interactive outdoor splash park.
- Wodonga WAVES: A great stop-off with large outdoor slides and a splash pad for younger children.11
- Mildura Waves: Known for its wave pool and seasonal inflatables, though the slides are smaller than the Melbourne theme parks.
Important Tips for 2025/2026 Season
- Height Restrictions: Most “Thrill” slides (Tornado, Tsunami, Thunder Falls) require riders to be at least 122cm tall so get your measuring tape out before you head off!
- Construction Update: The Maribyrnong Aquatic Centre (MAC) is currently undergoing a massive $16 million redevelopment. New slides and a splash park are expected to be fully operational by early 2026.
- Booking: For Adventure Park and Gumbuya World, booking online is highly recommended during the peak summer months (December–February) as they frequently hit capacity.
