The biggest names in Australian Ninja Warrior take on a brutal obstacle course with 3:45 on the clock and a spot in Grand Final Stage 2 up for grabs.

It's the Grand Final and the biggest night in Australian Ninja Warrior's History. Eight Ninjas will attempt to climb Mount Midoriyama to become Australia's first Ninja Warrior.

Ninja Warrior is back. After being conquered last year, Mount Midoriyama is angry. A tougher course with new obstacles will challenge the Ninjas like never before.
