The contestants were announced on 5 April 2024 and the season premiered on 14 April 2024.

Challenge 1

 * Challenge: "Break the Ice" Each of the eight teams has 14 hours to build on a round plate something that looks "cool" smashing through an ice field.

 * Challenge: "Go-Kart" Four teams of four as chosen by the winners of Challenge 1 (two Australian teams and two international teams) have eight hours and one minute to build the exterior of a go-kart chassis (Segway Ninebot GoKart). Brickman scores the build out of 10 for aesthetics and Hamish Blake awards three bonus points to the winner of the go-kart race (no go-kart made it through the race intact, so no points were awarded).
