The last of the heats promises to be the most competitive in Australian Ninja Warrior history as eight former grand finalists, including the three who have previously been the furthest fastest, are among the final 40 competitors who take on the Quintuple Steps, Butterfly Wall to Zipline, Bridge of Blades, Bar Hop, Basket Toss and Warped Wall as they compete for the last 16 spots in the semi-final, with the two fastest ninjas of the night facing off on the Power Tower for a chance to win a 10 second time advantage.
