The 30-year-old Wagga woman was last night introduced to Australia as one of the 14 housemates set to star in the Nine Network’s revamped Big Brother reality television show.

The former Trinity Senior High School student has followed in the footsteps of Wagga’s 2005 Big Brother winners, the “Logan” twins – Greg and David Mathew – trumping more than 20,000 who contested to take part in the show.

As news of Sarah’s selection filtered through Wagga, yesterday even her close friends and family were surprised at how closely her newest adventure had been kept under wraps.

“There is this veil of secrecy about it,” Sarah’s mum, Anne Wentworth-Perry said. 

While Sarah’s partner of two years Ryan Miller had accompanied her to the secret auditions in Melbourne, Ms Wentworth-Perry said she and Sarah’s sister Emma were among the first to find out last week. 

“I don’t think any of her friends know,” she said.

“I don’t think even the housemates know a lot either.”

Mr Miller said Sarah, who works as a new car sales consultant at Thomas Brothers Toyota, was keen to use her time on Big Brother to help raise awareness for the charity Little Paths which helps children in Cambodia and Tanzania living below the poverty line. 

“She loves what she does now with her job, but anything that pushes the charity forward is good,” he said.

While Mr Miller said he’ll be taking the storylines which arise from Big Brother with a grain of salt, both he and Ms Wentworth-Perry are keen to see how Sarah’s time on the show plays out.

“I’m just proud of her,” Ms Wentworth-Perry said.

“She gives 110 per cent to everything she does. 

“I’m sure she’ll give Big Brother 110 per cent as well.” 

Describing her daughter as bright, bubbly, kind-hearted and loyal, Ms Wentworth-Perry said there was only one little thing that worried her about Sarah’s stint as a housemate. 

“She is a little untidy,” she said.

“(But) she is always so busy.”
