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.

The second Heat sees the rise of a new breed of Ninja and the return of some of our greatest and most loved Ninjas as they battle it out on the toughest course we've ever seen.
