Big Brother returned to screens after a five-year hiatus on Monday with a diverse cast and a distinctly family-friendly makeover.
And those watching the program for the first time will find it hard to believe the early seasons had a raunchy companion show called Big Brother Uncut.
Uncut debuted on Channel 10 in 2001 as an adults-only adjunct to the early evening broadcast – and no act of debauchery was off limits.

Hosted by Gretel Killeen, Uncut was known for airing footage of the housemates showering, engaging in racy behaviour and discussing sexual matters.
Following a wave of complaints, the show was rebranded as Big Brother: Adults Only for the 2006 season and was eventually axed the following year.
Since its cancellation, the TV watchdog has enforced new rules about the depiction of sexual content, meaning that Big Brother Uncut will likely never return.
Here, Daily Mail Australia takes a look at the most shocking moments ever to air on the program.
Big Brother’s infamous ‘bondage party’
Big Brother Uncut raised eyebrows when it aired footage from a ‘bondage party’, which took place just days into the show’s 2001 season.
During a particularly wild night in the Big Brother house, bondage enthusiast Andrea Silva decided to demonstrate some of her sexual fetishes to the other housemates.

The part-time dominatrix tied up her shirtless co-stars, pinched their nipples and whipped them with a leather scourge as the other contestants watched on.
‘This is just warm-up!’ she giggled as the group cheered.
Andrea proceeded to attach a collar to Todd James’ neck, before leading him around like a dog in an act of humiliation.
Later that night, Andrea and Sara-Marie Fedele tied a shirtless Gordon Sloan to a wooden table before seductively caressing his bare chest.

Sara-Marie Fedele’s racy antics
Sara-Marie Fedele is still regarded to this day as one of the raunchiest housemates ever to set foot in the Big Brother house.
Known for her famous ‘bum dance’ in the 2001 series, she also raised eyebrows for her wild behaviour, which included shaking her breasts, slapping her bottom and inviting her male co-stars to touch her body.

In one episode of Big Brother Uncut, Sara-Marie stripped nude and began dancing around the crowded bedroom wearing just a pair of rabbit ears.
In another installment, the former strip club manager wiggled her breasts around in bed as housemate John Cass rested his head on her bosom.
‘Everyone needs a bosom for a pillow,’ she cooed.
A separate late-night scene showed Sara-Marie flashing her breasts at Blair McDonough and Ben Williams as they cuddled up in bed together.

‘Biggest boobs I’ve ever seen in the flesh. Biggest boobs ever,’ Blair said in awe.
Sara-Marie then invited the two men to squeeze her breasts, and they were more than happy to oblige.
Another early episode of Big Brother Uncut showed Sara-Marie passionately kissing bondage queen Andrea during a wild party game.

Late-night sex scene
Big Brother Uncut courted controversy in 2001 for airing a ‘sex scene’ between Peter Timbs and Christina Davis.
‘I might rape you if I see you naked in here,’ Christina jokingly told Peter when they were in bed together.
Later that night, infra-red footage showed the pair moving rhythmically underneath a doona.
Neither Peter nor Christina has actually confirmed they were having sex, however.
