The 26-year-old Luton Properties agent is one of 16 contestants who will spend every moment of a possible three months under the watchful eye of the Big Brother cameras.

Real Estate Institute of Australia president Peter Bushby said that while he hasn't watched the show for a number of years, he believes the experience could help a real estate professional in the long run.

"The thing with Big Brother is that you need to be something of an extrovert in the first place and if you go in with your eyes wide open, the world's certainly going to get you know better," he said.

"And certainly afterwards depending on how you're portrayed, they could turn out to be very well known. And if they stay in real estate they could go on to be a great identity. Real estate is a people industry - being well known is part of getting business."

Luton Properties director Richard Luton said he expected Roses to do well in the competition, as well as when he returns to regular life.

"He will go very, very well because he's actually got a heart and he's just a generally nice person and he's always thinking about other people," he said.

"He's a successful man in his own right and he's got a lot of loyal and following customers that he's done great results for in the past and I think that will continue."

This year's contestants must compete in pairs with complete strangers, with Roses paired up with 24-year-old fitness fanatic Dion.

"They'll be a good match. Jason goes to the gym and now he's got probably his own personal trainer for the next three months," Mr Luton said.
