Big Brother housemates shiver, grimace in pain and lose feeling in their legs as they spend SIX HOURS in the rain during tough challenge

Big Brother Australia’s reboot hosts physically and mentally demanding challenges every episode. 

And on Monday, the housemates competed in a deceivingly gruelling challenge within the compound’s backyard while a storm was brewing.

For six hours and 41 minutes, stars were seen in pain, shivering and struggling to stay upright as they performed the strange task as the rain poured down.

Housemates were each asked to use their hands and fingers to stop water from draining from their allocated funnels above their heads. 

Big Brother said housemates were allowed to leave their post at any time, but the water would completely drain after five minutes of being left uncovered. 

Not dressed for the drizzly weather, many stars quit early as they were too cold in their wet clothes.

After four hours of standing still, Hannah Campbell’s knees appeared to buckle as she hopped of her podium.

‘Oh my God, my legs! My legs have gone to sleep. My legs are asleep,’ she shrieked, while attempting to crawl out of the rain.

Even the muscular men of the group winced in pain as the hours ticked on.

Angela won the challenge after six hours and 41 minutes, and put Danni, Garth and Zoe up for eviction. 

Other housemates were tempted away from their positions with offers of treats in the Diary Room, including a puppy, a cooked steak and a game advantage.
