Australian Ninja Warrior
On Australian Ninja Warrior, Lee clocked the third fastest time in his heat (Heat 4) and took sixth place in his semifinal (Semifinal 2). During the grand final, he went out on the Globe Grasper in Stage One.
Australian Ninja Warrior 2
On Australian Ninja Warrior 2, Ben shockingly fell on the fourth obstacle in his heat (Heat 6), which was the Swing to Cargo Net. However, due to the fact that the second obstacle (the Bungee Slider to Bullet) became the cut off to advance to the semifinals, he still advanced to the semifinals. In his semifinal (Semifinal 4), he went out on the eight obstacle (the Hourglass to Tramp to Cargo Net) and took fourth place. During the grand final, he made all the way to Stage Two, before going out on the Salmon Ladder.
