Jack Wilson, also known as the Deadly Ninja, is a carpenter and educator from Gold Coast, Queensland, who firstly competed on Australian Ninja Warrior.
Australian Ninja Warrior
On Australian Ninja Warrior, Jack was notable to become the first competitor to complete the qualifying heat course, and then clocked the fifth fastest time in his heat (Heat 1). In his semifinal (Semifinal 3), he went out on the eighth obstacle (the Pole Grasper), when his foot touched the water at the end of the obstacle. However, his time was fast enough to advance to the grand final, as he finished in seventh place. During the grand final, he made all the way to Stage Two, before going out on the Basket Toss.
Australian Ninja Warrior 2
On Australian Ninja Warrior 2, Jack clocked the second fastest time in his heat (Heat 5). In his semifinal (Semifinal 1), he went out on the eighth obstacle once again (this time, the Hourglass to Tramp to Rope) and finished in fifth place. During the grand final, he made all the way to Stage Two, before going out on the Spider Jump.
