Episode 6-9

With bragging rights and cash prizes on the line, the Ninja all-stars will go head-to-head on five super-sized obstacles as they attempt to break international records.

It's the last of the Australian Ninja Warrior Semi Finals and the last chance for a coveted spot in the Grand Finals.

It's the first of the three semifinals and for the first time, two Ninjas will run head-to-head, knockout style, with only one Ninja from each making it to the Grand Final.
