When you dump a bunch of people into a house for 30 days, relationships are bound to form. That’s what we’ve seen on Big Brother Australia 2025 so far, with sparks flying between Coco Beeby and Bruce Dunne, as well as Colin Ridley and Holly Young. But are contestants allowed to have sex in the Big Brother Australia house, and are there strict rules around consent?
According to the latest evictee, Jane Marshall-Doherty, housemates are given a “code of conduct” before entering the house, with consent rules clearly outlined. “There is a code of conduct, and I think it’s 150 pages,” she tells Chattr. “Say a couple go off, like Coco and Bruce… you have to give consent to cuddle up and maybe kiss.”
It happens each time the housemates want to get close, so perhaps Big Brother gives them a nudge when he sees sparks start to fly. “You would be reminded of it. So if they’re hooking up, they’ll be reminded of it all the time,” Jane spills.
However, Jane wasn’t sure if people were actually allowed to have sex in the house, and she didn’t ask producers what sexual health supplies were provided. Considering she had an adverse reaction to two people kissing, this tracks.
“It’s a family show, so I don’t really know. I don’t know, I didn’t go and ask [for condoms],” she laughs.
A Channel 10 spokesperson confirmed that contestants must adhere to a specific code of conduct. “Big Brother runs a tight ship and has strict house rules everyone must follow. His code of conduct prioritises respect, consent and accountability,” they said.

Former Big Brother Australia housemate reveals more sex rules
Big Brother Australia 2021 runner-up Christina Podolyan recently shared a TikTok outlining some surprising rules the housemates have to follow, and she claimed they were allowed to have sex on her season.
“You have to ask Big Brother for permission before you get jiggy with it,” she revealed. “Let’s say you’re about to get it on, right. You’d literally have to get up, you have to go to the diary room… you have to say, ‘Big Brother, may I please have consent’… and then the other person has to come in and say, ‘Big Brother, may I please have your permission to get down and dirty with someone’, and then Big Brother says yes or no.”
Sounds like that would kill the mood!
Big Brother Australia 2025 airs Monday to Friday at 7.30pm, and Sundays at 7pm on Channel 10 and 10Play.
