Everyday Aussie heroes - plus top sportsmen and women - take a shot at the world's hardest obstacle course.

The second heat of Oz's take on the hit format features the Battle of the Tradies and a former elite gymnast.

50 new competitors face the Ninja course in the third heat, but three new obstacles make a debut as well...

Rugby league star Beau Ryan and Australian football star Adam Cooney compete in a Battle of the Codes.

It's the final heat before the semi-finals, and 50 Ninjas are competing for the last 18 spots this time.

It's the first semi-final - if the Ninjas thought that the heats were tough, they haven't seen anything yet!

It's the second of the three semi-finals - 30 Ninjas take their shot at glory, but only seven can qualify.

We're now eight episodes in, but do you think that this version has lived up to its global reputation?

The very first Australian Ninja Warrior Grand Final sees the final 21 Ninjas gather for one last battle.
