Forget about tech-heavy toys and gizmos: kids can still have hours of fun bouncing up and down in a jumping castle. But this landmark pop-up is no ordinary experience, with The Big Bounce Australia featuring the world's largest jumping castle. Spanning a mind-boggling 1500 square metres, this sprawling inflatable contains slides, climbing walls, ball pits, basketball hoops and a central performance area with music and hosted activities. Plus, this huge blow-up runs alongside a 300-metre obstacle course, complete with over 50 challenges that'll test kids of all ages (not to mention adults). Leap into the galaxy-themed airSPACE zone, home to a five-lane slide, multiple elevated platforms and moon craters filled with balls. Meanwhile, the Sport Slam zone is jam-packed with goals, nets, hoops and balls so that everyone can bounce and compete at the same time. Touring nationally, The Big Bounce Australia is now at Flemington Racecourse in Melbourne until Sunday, January 11, before travelling to Canberra, Brisbane, Sydney, Adelaide and Perth over the next three months. With tickets starting from $40, three-hour sessions are held for toddlers, juniors and bigger kids. And for those aged 16 and older, adult-only sessions give you the chance to tackle this bouncy wonderland. "We are pleased to begin the tour in Melbourne, where there is strong demand for active, outdoor entertainment throughout summer," says Noa Overby, Tour Manager for Big Bounce Australia, "The Big Bounce offers a broad mix of activities that appeal to a wide range of ages and encourages people to get involved in something that is both social and physical."
