Filming for the long-awaited new season of SAS Australia is well underway in the Blue Mountains, NSW.
And on Wednesday, the celebrity recruits were pictured taking part in a brutal challenge where they had to escape from a camouflage Jeep while submerged underwater.
Despite being surrounded by his fellow recruits, a dripping wet Sam Burgess wasn’t afraid to whip off all his clothes following his brief dip – unveiling his bare bottom in the process.

Moments prior, the former NRL star, 32, was seen flaunting his muscular arms and abs in nothing but a pair of tiny black boxers, as his fellow recruits waited patiently for their challenge to begin.
Hunky model Jett Kenny was also showed off his equally as impressive body, wearing a pair of camo trousers and a waistband.
Prior to stripping off, the recruits – including Erin Holland, Heath Shaw and Isabelle Cornish – filmed next to a huge Jeep.

The vehicle was seen being airlifted into the water, before the celebrity gang swam around in the lake after seemingly escaping from the car.
Some of the recruits looked nervous as they lined up at the side of the lake, holding their hands in front as they waited for their name to be called.
Two cast members who appeared to be missing from filming were Manu Feildel and Brynne Edelsten, which could indicate that the pair have left the show early.
This season, the Blue Mountains training camp is set amid an abundance of trees and rolling mountains.
While minimal details have been revealed about this year’s location, the 2020 base camp was created using corrugated iron structures which provided little warmth for the show’s contestants.

Built on an isolated sheep station, there was originally no structures on the camp site with the buildings erected for the show.
At the end of each bed was a metal trunk with a bucket on top, and a row of wooden drying racks lined the centre of the room.
The series will also feature Olympic runner John Steffensen, volleyball champion Kerri Pottharst, Bra Boy Koby Abberton, tennis player Mark Philippoussis and singer Pete Murray.

Former Special Forces soldiers Mark ‘Billy’ Billingham, Jason ‘Foxy’ Fox and Matthew ‘Ollie’ Ollerton are also all returning to the show alongside Ant Middleton.
Speaking to 7News on Monday, Ant, 40 said: ‘Living in our world will be the rawest and most brutal life lesson these celebrities will ever experience.’
‘We aren’t holding anything back, it’s as authentic as it gets,’ he added.
