Australian Ninja Warrior
On Australian Ninja Warrior, Andrea made all the way to the Warped Wall in her heat (Heat 4). However, she couldn't scale it after three attempts and finished in 11th place. In her semifinal (Semifinal 2), she was able to scale the Warped Wall, becoming the first woman ever in Australian Ninja Warrior history to do so, and made all the way to the eighth obstacle (the Pole Grasper), but her performance wasn't good enough to qualify to the grand final.
Australian Ninja Warrior 2
On Australian Ninja Warrior 2, Andrea was able to scale the Warped Wall and complete the qualifying heat course in her heat (Heat 6), becoming the sixth woman ever to do so on Australian Ninja Warrior. In her semifinal (Semifinal 2), she went out on the seventh obstacle (the Salmon Ladder to Floating Monkey).
