In the exclusive report, journalist Reid Butler ambushes the former Wallaby at a luxury hotel to ask about his decision to dump Brittany Hockley and Sophie Tieman in last weeks finale.
The "Honey Badger" has been spending time there while completing the Kokoda Trail.
Butler asked some tough questions, surprising the former rugby star who appeared frustrated at the ambush.
"I'm just trying to have a peaceful break," Cummins, said, after emerging from a swimming pool.
"Just don't bloody hassle me, I'm trying to bloody crunch it out. Got enough crap from people like you, so I'm just trying to relax."
PR guru Roxy Jacenko also weighed in on the program.
"I think the feedback that's out there in the media at the moment saying, you know, 'We hate him' is disappointing," she added. "I think the smarter feedback should be, you know what? The guy did the right thing. He wasn't in love with either."
