MOST of us know Rove from his time in front of the camera, but it’s been revealed that the Aussie star also plays a huge role behind the scenes of one of America’s biggest TV shows.

The 41-year-old, who is currently the host of the 2Day FM breakfast show in Sydney with Sam Frost, is a massive Survivor fan and helps out during rehearsals on the reality show.

The host of all 31 seasons of the TV juggernaut, Jeff Probst, appeared on Rove & Sam this morning and revealed the extent of Rove’s involvement.

“Rove comes to location a lot with Taz (his wife Tasma Walton) and it’s a blast and he participates in the challenges,” Probst said.

“I’m not exaggerating Sam, I’m really not, he dominates. We have these challenges that are gigantic and exhausting, I mean punishingly exhausting. And then you get to the top and there’s a puzzle to solve. Rove has won, I don’t know how many, five of the challenges against our dream team, these 20-year-old men and women that we pay to rehearse these challenges.”

Rove and Jeff Probst are good mates, but it’s not just the US TV host who is excited to see the Aussie entertainer when he visits the set.

“I’d say probably 40 per cent at least of our crew are Australians,” said Probst on air this morning.

“I remember the first time he visited, we have a call sheet that goes out ... and it says ‘Rove McManus’ and all day people are going, ‘Hey Probst, there’s a guy on the call sheet, it says Rove McManus is arriving. That doesn’t happen to be a guy from Australia?’ I go, ‘yeah, Rove’.”

Not only does Rove help out during rehearsals, but he’s also the man behind some of Probst’s witty one-liners that make it to air.

“If Rove’s not there in person, I’ll email him and say, ‘Alright, there’s a round disc and some balls, I need lines’,” said Probst.

“He’ll just start shooting off one-liners to me and I try to remember as many as I can and then pull them out during the challenge and take credit for them.”

Added Rove, “‘Pull it out during a challenge’ was also one of my jokes that I wrote for him.”

Applications are currently open for an Australian series of Survivor which will air on Network Ten later this year.

The host hasn’t yet been named, but if Probst gets his way, it’ll be Rove delivering that famous line, “The tribe has spoken, it’s time for you to go”.

“I’ve told him, if something happens to me on location and I had to leave, everyone knows the guy to call is you,” said Probst to ET Canada in September.
