"MANY of the situations are pretty tough - we're seen as the last resort, the knights in shining armour.
"We've done nine seasons of this show - can you believe it? In that time we've found some really, really hard properties to sell. Ones that we just don't even know what to do with. There have even been a few that we wondered whether it'd be better to knock them down. 
"This is a show about real people, real life, and some of them are in real trouble for a variety of reasons. They need to sell and we're there to help them, not sensationalise their story.
"Some are quite vulnerable. It's important we don't exacerbate that pressure - we're there to do what we can to help.
"There's a story coming up in the new series that will stick with me for a long time. I can't say much yet, but we come to the aid of a homeowner who's quite unwell and knows they won't be around for much longer. It's a case of selling the house so those left behind won't have to deal with the burden of it. It's really tough and was so poignant for me.
"The person's outlook is so amazing and positive, though. They're just beautifully positive and don't get bogged down in it. That made it hurt even more for me.
"It's moments like those I really cherish, being able to get in and make a difference. When we arrive, many of the situations are pretty tough. We're seen as the last resort, the knights in shining armour.
"But, in the beginning, it was quite daunting. The show was new and untested so we were scratching around and begging for paint and other bits and pieces.
"And we did lots and lots of the work ourselves. We were quite creative. I remember hand painting tiles. Now we have so many great products to work with.
"The market is savvier now. People are very savvy. When I first started on Selling Houses, staging a property wasn't the thing to do.
"No one styled or staged their home for sale but now you'd be insane not to. "Markets have also obviously changed. The (housing) markets in (Sydney and Melbourne) particularly have gone crazy so stuff that shouldn't normally sell is getting snapped up.
"It's not reflective of reality. We've had to broaden our scope and go further to get realistic situations.That almost adds a layer of difficulty! It's like, how on Earth can we actually do this? But we get stuck in and achieving a result is the best feeling."SELLING HOUSE AUSTRALIA, WEDNESDAY, 8PM, LIFESTYLE
