It started out as an affectionate name used between family members – now 'Chump' has gone global! And Rod and Tania couldn’t be more proud.

"It's unbelievable that after so long the whole 'Chump' thing is still being talked about," says Rod, who admits he was thrilled when producers asked him to return to the series this week to present a 'Chump hat' to the losing contestants for Room One.

"And did you know they now play our series of The Block in New Zealand and The Netherlands? It's also on in the UK at the moment," Tania adds, incredulously. "I keep saying to Rod, 'Hon, you do realise you've now showed your arse to everyone around the world?!'"

Jokes aside, Rod and Tania are thrilled to be back talking about the show they say has changed their lives. Not only did they end up walking away from last year's series with a prize pool of over $72,000, it's also made them totally overhaul how they live.

"We've got a lot of projects in the works," says Rod, who is in the process of selling his sheet metal business in Warragul, regional Victoria.

"We have still got this major reno to do on our house, which we have plans drawn up for, but we've also started looking at properties in Melbourne to get a hold of to renovate."

Clearly they weren’t put off by the idea of fixing up houses after last year's series.

"It was good like that," Rod admits. "The show totally changed our perspective on renovating. This time around we're not going to stuff around. Like, I won't be doing 'one room a week' or anything like that, but I plan on doing this house a lot faster."

Once their business is sold it will mean Rod and Tania have the freedom to look at renovating properties full time – something they still see as a luxury.

"It will be nice just to be able to renovate," says Tania. "That was one of the things we liked best about The Block – that we didn’t have to work and could renovate full time."

"If we can do up houses and make a quid off them – that would be great," Rod adds.

And that's not all they have planned – in two weeks Rod will hit the road with fellow contestant, and now close friend, Waz on an epic road trip adventure.

"We are going to North Queensland to shoot a bit of a pilot for an adventure travel show," says Rod. "The idea is that it will be done on a budget that is a bit more applicable to most Australians. The main concept is 'Expose Australia' and we also want to find those three-toothed blokes in the pub with a bit of a story to tell."

So could Rod and Waz be Australia’s next Leyland Brothers, famed adventurers from the seventies who filmed their trips around Australia?

"I said that to Waz and he said, 'Who's the Leyland Brothers?'" Rod says. "I have gone, 'Waz, you really have had a deprived childhood!'"
