Peter Nixon, whose daughter is Big Brother contestant Sandra, wants "as many people as possible" to vote to save the housemate from eviction.

Sandra, a well-known softballer with Kooringal, and manager of Wagga's Bonds store, received 14 votes with her pair David the second highest of the four pairs up for eviction.

"The fact they are in a pair hasn't necessarily helped her cause," Mr Nixon said.

"But in the end it is just a game."

Mr Nixon said he is unsure how Australia will vote come eviction night next Tuesday at 8.40pm on the WIN Network.

"Most certainly, I'd love to see as many people as possible save her," he said.

"She is a Wagga girl."

The father of Wagga's Big Brother 2014 contestant Sandra Nixon has revealed she was nominated by a friend to enter the house.

But Sandra's father, Peter Nixon, sees Sandra's initial reluctance to grace the small screen as her most valuable asset.

Mr Nixon said if the power of humility prevails, Sandra could bring home the money pot. 

"She said right from the start she was going to go in there and be herself and that's what she said to the production crew all along," he said.

"She said 'I'm not going to go in there and be someone else'."

Best known for her sporting prowess with softball club Kooringal, Sandra was working as a manager at Wagga's Bonds store before entering the competition.

Despite the initial hype and ceremony as she entered the house last week, Sandra has this week received little screen time. 

Mr Nixon said the first few weeks will be Sandra's biggest challenge as she battles it out to carve her name between the 19 other housemates.

"The others seem to be getting a lot of the limelight," he said.

"But if she gets through the first few weeks without being evicted, I think she has a chance of doing quite well.

"People will get an opportunity to see her personality and the fact that she is genuine."

Under a Big Brother twist, Sandra has entered the house with a partner, David, of Goulburn.

Mr Nixon said the partnership is the best opportunity for Sandra because her sense of humour "bounces off people".

"She has an excellent sense of humour," he said.

"Most people would say she's really bubbly and has a good personality. It's what she's known for."

Probably like most fathers, Mr Nixon felt some "trepidation" with Sandra entering the house. 

He has spoken frequently with his wife, Helen, about how the duo would cope without seeing Sandra for weeks on end.

"That's probably the main hesitation we had," he said.

"But she's an adult now so she can do what she likes and I'll always support what she does.

"There was plenty of excitement when she was announced because it's a pretty big achievement. 13,000 people auditioned in the first place."

Mr Nixon said he would remain proud of Sandra regardless of the outcome.

"Whatever will be will be," he said.

Being the first to admit he's not a Big Brother fan, Mr Nixon said only one thing would change should Sandra be evicted: "I think I'll flick over to the footy."
