Conditions on the set of SAS: Australia are not for the faint-hearted.
The contestants sleep on a cot bed that swimmer James Magnussen joked he "went through four of", with no access to hot water or flushing toilets. And with temperatures at base ranging from a minimum of -5°C to a maximum of 8°C, it gets pretty chilly.
No personal items are allowed, but the recruits are given a "house on your back", also known as a Bergen, that contains every item they need.
This includes a helmet, chest harness, sleeping mat, tarp, towel, water bottle, knife, mess kit, mug, toilet roll, sanitising wipes, sunglasses, head torch, notebook, pencil, toothpaste, toothbrush, belt, armband, whistle, watch, sleeping bag, compass and two sets of kit (clothing).
One of the recruits, Ali Oetjen, revealed exactly what it was like filming the intense series.
"We didn't take anything in apart from the clothes we were wearing. We were issued a backpack with everything we needed. No hot water, no showers, no flushing toilets. Sleep & food deprived, riddled with adrenaline, fear & exhaustion," the former Bachelorette explained.
"The physical pain like cuts on my throat, hands all cut up, blistered feet, black & purple bruises which covered my legs and arms weren't the worst thing. The WORST thing was the cold & calming my mind to keep going!"
"Freezing temperatures ALL the time with no respite, being wet with the chill winds made it so much worse. -5 to 8 degrees!"
The recruits are under the eye of the directing staff (DS) led by the formidable Ant Middleton who admits he doesn't feel sorry for any of the recruits.
"I don’t care if recruits pass the course – I am not there to be friends with anyone," he revealed in an official statement.
"I am there to make sure the participants overcome their fears and drive them to push themselves to develop the attributes necessary to pass the course."
