Beauty and the Geek Australia - 3 ª Season

Nine new beauties are paired up with nine new geeks. The geeks are set a "Fashion-atomy" challenge where they have to paint specific clothing items on their beauties before having their creations judged by Camilla Franks. The beauties perform a "Round the World" challenge where they have to match some foods to the countries with which they are most associated. The winners of the two challenges each nominate a team to send to the Elimination Room, where they participate in a quiz in which the team with fewer correct answers is eliminated.

The eight remaining beauties and geeks receive a surprise when a male beauty and female geek join them in the mansion. The beauties take part in a zoology challenge where they have to put their hands into five crates, feel the animal inside each and then name the animal. Immunity is offered to the first beauty to retrieve a disk from a crate with 50,000 cockroaches inside using their mouth. The geeks are set a "What's Your Number?" challenge where they each have to flirt and find interests with a person of the opposite sex with the ultimate aim of asking them for their number. The winners of the two challenges each nominate a team to send to the Elimination Room, where they participate in a quiz in which the team with fewer correct answers is eliminated.

The eight remaining beauties and geeks take part in a hero challenge where each of them shoot balls of paint, the beauties at geek heroes and the geeks at beauty heroes, before having to name the hero. The geeks then compete in a roller derby in which a Sydney women's team tries to knock them over, with the last two geeks standing then having to protect their beauties from falling over. The winners of the two challenges each nominate a team to send to the Elimination Room, where they participate in a quiz in which the team with fewer correct answers is eliminated.

The seven remaining beauties and geeks go back to school, where the beauties have to teach a Year 7 class one of four subjects - physics, chemistry, biology or vulcanology. The geeks then pair up with their beauties to choreograph and perform a cheerleading routine, from which the best two couples compete with a professional team of cheerleaders. The winners of the two challenges each nominate a team to send to the Elimination Room, where they participate in a quiz in which the team with fewer correct answers is eliminated.

The six remaining beauties and geeks have to pose in their underwear for a photo-shoot. The couple whose photo is judged to be the best would appear on the cover of the Famous magazine, and the top two couples' geeks are the first to be given a makeover. The geeks then go out on a date with a geek of the opposite sex chosen specifically to match their interests, where their beauties have to serve the geeky couples as waitresses. After the dates are over, the geeks are given a chance to swap their beauty for their geek date.
