Published on 10 January 2020

The Big Bounce will be at the Showground between 25 January and 9 February.

Officially registered by the Guinness Book of Records as the world’s biggest jumping castle, the Big Bounce is touring six locations in Australia during 2020. St Ives Showground is the only NSW location; others include Melbourne, Adelaide, Brisbane and Perth.

The Big Bounce has a 300-metre long inflatable obstacle course and a three part space-themed wonderland suitable for children and adults alike. 

The jumping castle is over 1500 square metres with some sections reaching over 10 metres tall. Inside you’ll find various zones, each with its own unique theme and activity-based entertainment.  Features range from giant slides, obstacle runs, ball pits through to climbing towers, basketball hoops and over-sized inflatable characters of various colours and shapes.

Two other attractions are the Beast - over 300 metres in length and with 50 inflatable obstacles to overcome - and the Airspace, a space-themed wonderland filled with friendly aliens, spaceships, moon craters, a gigantic 5-lane slide and an 8-metre-tall alien at the centre of the 18-metre-tall maze.  

According to the Big Bounce Australia team, they have created an action-packed day out, offering different sessions throughout the day designed to cater for all ages including special adults-only sessions. There are designated areas for smaller children, ensuring everyone in the family has a safe and enjoyable day out.
