# Australian Ninja Warrior season 4

The fourth season of the sports entertainment reality competition series Australian Ninja Warrior premiered on 26 July 2020 on the Nine Network. The season is hosted by Rebecca Maddern, Ben Fordham, Freddie Flintoff and Shane Crawford.

## Production

On 17 October 2019, the series was officially renewed for a fourth season at Nine's upfronts, also confirming Fordham, Maddern and Flintoff were returning. The series was again relocated, with filming taking place at Melbourne Showgrounds in Ascot Vale. Due to the COVID-19 pandemic, production introduced audience lock-out, meaning members of the public could not attend as audience; only family members of contestants were allowed to attend. Co-host Rebecca Maddern, was temporarily placed in self-isolation and replaced by Shane Crawford for two heats, before being cleared and returning to filming. Crawford returned to the season as the sideline commentator for the semis and Grand Final after Freddie Flintoff had to fly back to the UK before coronavirus pandemic measures came into effect.

## Format Changes

* Power Tower - The Power Tower will see the two furthest fastest Ninjas from each heat and semi-final run go head-to-head side by side on an all new obstacle, climbing five 1.5m high steps, before a 2.35m leap to the first bar, travel 4.5m to the vertical pole, which they will slide down to an unsteady horizontal beam, move across a 3m beam to the next pole and climb 5.5m, then lache 1.75m to the horizontal ladder before leaping onto the platform and race to hit the buzzer.
** Advantages
*** Heats - The winner will receive a 10-second time advantage into the semi-finals, meaning 10 seconds will be taken off their final time.
*** Semi-finals - The winner will receive a second chance advantage into the Grand Final, meaning if they make a mistake during their run, they can re-run the course again.

## Rounds

Underline represents the contestant who won the Speed Pass in the qualifying heats as a result of winning the head to head competition on the Power Tower.
Green represents the contestant who won the Safety Pass in the semi-finals as a result of winning the head to head competition on the Power Tower.
