More than 50,000 people applied to become Big Brother housemates this year.
Of those people only 20 were able to enter the house - one of them being proud Macarthur local Chad Hurst.
Mr Hurst, who grew up in Eagle Vale, said he was inspired by his father to try and get on the show.
"It was dad's favourite show when we were growing up," he said.
"Dad's gone now, but there are pictures of him with past winners and when we'd watch it together he'd say to me, 'this is your show Chad, you should be on this show'.
"So that's exactly why I decided to apply - it was something he had always wanted me to do."
Big Brother is a reality show where 20 people live inside a house, participate in challenges and eliminate each other for the chance to win $250,000.
The 27-year-old said he never expected to be one of the few people selected to go inside the house.
"I didn't know about the new format but I did like the idea that it was going to be a PG show rather than an MA one," Mr Hurst said.
"I was dirty when I found out I was an intruder though. They sent us into the house at like 2am and I thought to myself, 'I'm an intruder, aren't I?'
"It's harder to make friendships and get into those little groups when you are coming in after everyone else."
The tradie-turned-model said he didn't go into the house with a game plan - and he also never expected to have a house romance.
"I didn't go into the house looking for a girl - I think Big Brother stitched us up," he laughed.
"Sophie is just such a nice girl, she was really energetic and someone I could have a laugh with."
Mr Hurst said the biggest game player in the house was Kieran.
"I think he'd even tell you to your face that he is there to play the game," he said.
"I think everyone had their own strategies though."
Mr Hurst said the eviction and shopping challenges kept housemates entertained throughout the week.
"The challenges were good - the hardest one for me was standing on the narrow poles and having to balance with someone," he said.
"That was the hardest thing I've ever done.
"I also learnt not to drink too much coffee before a challenge because you'd get the shakes."
The proud local said he spoke about his hometown a lot in the house.
"They edited a lot of it out but I always always talking about Campbelltown," the former Eagle Vale High School student said.
"Everyone in that house knows about Campbelltown now.
"I wanted to prove that us Westies can do these shows - I spoke about Campbelltown a lot."
Mr Hurst also had some advice for people hoping to get on the show next year.
"Big Brother is back so jump on board," he said.
"It's an awesome show and great for the whole family - it's not nasty or too much drama, it's just a lot of fun and it's very addictive.
"Just don't go in with a game plan. Have some fun so that you're not going to go in there to struggle and stress out."
Big Brother continues on Sunday at 7pm and from Monday-Tuesday at 7.30pm on Seven.
