"I don't really follow any religion, but I guess if I was to follow a religion, Barbie would be my God as she's done great for the world."
Bre, a country girl from Wagga, NSW, has never outgrown her childhood obsession with the colour pink and Barbie.
"Since I was a little girl my bedroom was completely covered in pink Barbie stickers and littered with every type of Barbie and all her matching pink accessories," says Breana.
"I still have and treasure all my Barbies and her hot pink accessories and have actually brought a few of them and my Barbie dog along with me to the mansion."
Although her love of Barbie could be seen as childish, Bre actually moved out of home at the tender age of 16 to attend school and has been living away from home ever since.
"I have lived by myself for the past two years so I'm really proud of myself for being able to accomplish that at such a young age," she says.
Bubbly and incredibly girly, Breana reveals her perfect guy would be "good looking, easy going and generous" and her perfect date would include "pigging out on lollies and having a blast at a theme park".
Describing herself as always having a positive outlook on life, Breana hopes to teach the Geeks how to make her culinary speciality - a sugar sandwich - and how to feel comfortable in their own skin.
"I hope I can just teach them to be happy the way they are," she says.
"One reason why I like Barbie so much is because even when people criticised her for not having realistic body measurements, she defied everyone by sticking to her guns and not changing, sending the message that you are who you are and you shouldn't let anyone change you."
Breana hopes the Geeks can help her with maths, a subject she never understood at school.
