  1. Bouncy Castles: Best for Younger Kids and Small & Medium Events

If your event is aimed at early childhood or primary-aged kids, you can’t go wrong with a bouncy castle. They are bright, simple and safe making them ideal for family fun days, school fairs and council community events.

When Bouncy Castles Are the Right Choice

Choose a bouncy castle when:
  • Your audience is mainly kids aged 3–10
  • You have limited space
  • You need non-intimidating entertainment
  • You want something easy to supervise
Bouncy castles come in various sizes and themes, making it easy to match your school or council event.

Space Requirements

Smaller castles can fit in tight school yards, indoor halls or council venues. Larger castles require a grassed oval, park space or open area.

Why Schools & Councils Love Them

  • Affordable to hire
  • Safe & soft surfaces
  • Encourage constant activity
  • Easy to rotate groups through
  • Perfect for lower-key events

  1. Water Slides: Great for Summer Events and High-Energy Crowds

Water slides are unbeatable when it comes to summer events and hot-weather school carnivals. They’re exciting, dynamic and an instant magnet for older kids and teens.

When Water Slides Are the Right Choice

Choose a water slide when:
  • Your event is in spring or summer
  • You’re catering to ages 6+
  • You want high-engagement, fast-paced fun
  • Your venue has water access
  • You’re hosting a full-day carnival or community festival
Water slides come in many sizes from smaller backyard-friendly slides to giant multi-lane racing slides perfect for large school events.Water Slide Hire

Space Requirements

Water slides require a bit more space due to the landing zones, splash pools and safety clearance areas. School ovals, parklands and council recreation spaces are ideal.

Why Schools & Councils Love Them

  • Big visual impact
  • High throughput for large crowds
  • Keeps kids cool in warmer months
  • Perfect for fundraising events
  • A highlight attraction residents talk about
Schools often pair a water slide with smaller inflatables to create a mixed-age entertainment zone.See Monsterball’s full range of water slides under our Water Slide Hire Perth options for ideas.

  1. Obstacle Courses: Ideal for Large Events and Mixed Age Groups

If you’re organising a community day, school carnival, youth event or festival, obstacle courses offer the perfect balance of excitement, challenge and inclusivity.

When Obstacle Courses Are the Right Choice

Choose an obstacle course when:
  • Your event attracts all age groups
  • You want something team-based or competitive
  • You need high-capacity entertainment that moves fast
  • You’re hosting a sports carnival or high-activity day
  • You want a main attraction that stands out 
Obstacle courses also allow organisers to run races, relays, competitions and timed challenges great for school programs or sporting clubs.

Space Requirements

Obstacle courses are longer and require more ground space. Many schools and councils set them up on:
  • Ovals
  • Fenced fields
  • Open parkland
  • Indoor sports courts

Why They’re a Top Pick
