Hosts Ben Fordham, Rebecca Maddern and Freddie Flintoff guide 300 new Ninja Warrior hopefuls.
A mix of old and new contestants try out their luck, including NRL legend Paul Gallen, super mum Tash Sergi, and tradie Sam Goodall. Only one of them can win the title of Australian Ninja Warrior.
Some favourites of the season make their return, and Australia's most notorious party boy Corey Worthington and Red Wiggle Simon Pryce try their luck on the course.
The qualifying heats sees the return of some favourites including Francis Cullimore, Ashlin Herbert, parkour twins Brodie and Dylan Pawson, and three of Australia's top female gymnasts: Celeste Dixon, Larrissa Miller, and Georgia Bonora.
All eyes are on the ninjas as the semi-final spots are filling fast. Plus, ninja favourite Deadly Jack Wilson returns to take on the course.
The lightest and heaviest ninjas compete in the last of the heats, with ex-Bachelor Tim Robards and exercise physiologist Andrea Hah taking to the course.
