Everything you need to know before booking a jumping castle for your next Gold Coast party or event.

Whether you're planning a backyard birthday bash, a school fete, or an adults-only event, a jumping castle hire is one of the surest ways to guarantee a great time on the Gold Coast. But not all jumping castles are created equal, size, weight limits, safety ratings, and features vary enormously between kids' models and adult-sized inflatables. This guide breaks it all down so you can book with confidence from Rentsy's jumping castle listings.

Kids Jumping Castles

Designed for children up to around 12 years old, kids' jumping castles come in a wide variety of shapes, themes, and configurations. Here are the most popular styles available for hire on the Gold Coast.

Classic Bounce Castle

The original and most popular choice for younger children, the classic bouncy castle features a fully enclosed jumping area with mesh walls for visibility and ventilation. Safe, sturdy, and simple, ideal for toddlers and primary school-aged kids at backyard birthday parties. Typically accommodates 6–8 small children at once.

Ages 2–12Up to ~80kg total load3m × 3m footprint

Jumping Castle with Slide

A step up from the classic, the combo castle with inflatable slide is one of the most requested styles on the Gold Coast. Kids bounce, then zoom down a slide, keeping energy levels sky-high for hours. Look for dual-lane slide versions to reduce queuing and keep things flowing. Perfect for parties of 15 or more children.

Ages 3–124m × 5m footprintMax ~100kg load

Themed Jumping Castles

From unicorns and princesses to superheroes and dinosaurs, a themed inflatable castle takes the party atmosphere to the next level. These are fantastic for character-themed birthday parties and make for brilliant statement decorations in their own right. The vivid graphics and fun shapes keep kids engaged from the moment they arrive.

Toddler Jumping Castles

Specially designed with lower walls, softer surfaces, and gentle colour schemes, the toddler castle is the safest option for children aged 1–4. Smaller in scale, these are perfect for first birthday celebrations, playgroup events, and daycare parties. Often paired with a soft play zone setup for a complete little ones' activity area.

Inflatable Water Slide Combo

Built for Gold Coast summers, the water slide jumping castle combines a bounce area with a soaking wet slide — an absolute crowd-pleaser at backyard summer parties. Requires a garden hose connection and a suitable drainage area, but the payoff in pure joy is unmatched. Pair with a sun shelter or shade marquee to keep adults comfortable in the heat.

Mini Obstacle Course

More than just bouncing, the kids' inflatable obstacle course has tunnels, climbing walls, pop-ups, and slides in one continuous run. Great for burning energy and encouraging friendly competition among school-aged children. Often offered with a games package for a full party activity lineup.

Adult Jumping Castles

Yes, jumping castles for adults are a real (and wildly popular) thing. Reinforced, oversized, and engineered for heavier loads, adult inflatables are increasingly appearing at corporate events, 21st and 30th birthdays, hens parties, and music festivals across the Gold Coast.

Adult Bounce Castle

The adult-sized jumping castle is built with heavy-duty reinforced PVC and a high-powered blower to maintain pressure under the weight of adults. Taller walls and a larger jumping surface mean up to 10 adults can bounce simultaneously. A guaranteed icebreaker at corporate team days and milestone birthday parties alike.

Adults 18+Up to ~500kg total load5m × 5m footprint

Adult Inflatable Obstacle Course

Bring out the competitive spirit at your next corporate event or team-building day with an adult inflatable obstacle course. With climbing walls, balance beams, tunnels, and a finish-line slide, these courses run 10–15 metres and create instant tournament-style fun. Pair with a timing system and scoreboard for maximum friendly competition.

Adults & teens 10–15m run length Dual-lane available

Sumo Suits & Inflatable Wrestling Ring

One of the most entertaining add-ons to any adult event, the inflatable sumo wrestling setup pairs padded sumo suits with an enclosed bouncy ring. It's hilarious, safe, and completely inclusive, a perfect entertainment feature for hens parties, 21st birthdays, and corporate fun days where you want big laughs with minimal effort.

Giant Inflatable Slide

Standing up to 6 metres tall, the giant inflatable slide is a showstopper at outdoor festivals, school fetes, and large corporate events. Adults and older teens climb a reinforced ladder and hurtle down at exhilarating speed. Available in single and double lanes. Requires a larger setup area, combine with a shade marquee to keep the queue cool.

Inflatable Bungee Run

Two competitors strap on bungee harnesses and race to place a marker as far down an inflatable lane as possible before being snapped back. The bungee run is endlessly entertaining to watch and compete in a brilliant centrepiece for outdoor festivals, sporting events, and large backyard parties on the Gold Coast.

Ages 10+Dual-lane race12m+ length

Adult Inflatable Water Slide

Designed for the Gold Coast heat, the adult water slide inflatable features a steeper pitch, wider lane, and reinforced splash pool at the base.

Kids vs Adult: Key Differences Compared

Hiring Tips for Gold Coast Events

Measure Your Space First

Always measure your backyard or venue before browsing jumping castle options. Allow at least 1m of clearance around all sides and check for overhanging trees or power lines.

Check Your Power Supply

Most kids' castles run off a standard 10A outlet. Larger adult inflatables may need a dedicated circuit or a generator hire, always confirm blower requirements before booking.

Plan for Gold Coast Heat

Set up a shade marquee or outdoor umbrellas near the castle so guests can cool off. A water slide option is worth considering for summer bookings.

Bundle Your Party Hire

Maximise your event by pairing a jumping castle with outdoor games, a popcorn machine, and party tables and chairs for a complete event package.

Have a Wet Weather Plan

Gold Coast weather can be unpredictable. Ask about wet weather policies before booking, and consider hiring a large event marquee that can shelter both the castle and your guests.

Supervision is Non-Negotiable

Kids' castles always require at least one responsible adult supervisor on site. For mixed-age events, consider hiring two inflatables, one toddler castle and one older kids castle.

Feed the Fun

Keep the party energy up with a BBQ grill hire and a drinks station. For adults, a cocktail bar setup pairs perfectly with an evening inflatable event.

Set the Scene Around It

Dress up the area around your castle with party decorations, string lights, and a photo booth so guests have something to do between bouncing sessions.

Which Jumping Castle Should You Hire?

If you're hosting a children's birthday party, a kids' jumping castle or a combo castle with slide is almost always the best choice, safe, appropriately sized, and endlessly entertaining for younger guests. For mixed-age or adult events, an adult inflatable or obstacle course brings the fun without the safety compromise of overloading a kids' unit. For the ultimate Gold Coast summer event, opt for an inflatable water slide and complete the package with a shade marquee, lawn games, and a BBQ setup for a truly memorable day. Browse everything available on Rentsy and book the right castle for your next Gold Coast event.
