Talking to BBC Radio 5 Live podcast, the 41-year-old discovered a way to make his life easier.
The Brit discovered smoking is not broadcast on Australia TV, so he hatched a plan.
"I said 'I'm a smoker', which I'm not by any stretch," he shared.
"They asked me how many I wanted a day so I said five knowing I'd have to do it off screen."
"I'd walk out the gate and there'd be a chair with a cigarette that I didn't have, I just sat and had some peace to myself, not filmed and in nobody's hearing."
That lie helped see him to the finish line.
He also used the medic's out of bounds water rather than collecting his own - where you need to boil it so it is drinkable.
"I was more hydrated than I'd ever been in my life," he divulged.
"[My wee] was crystal clear. After a few days, I was thinking, "they must think I'm a camel". Nobody's seen me drink."
His antics didn't stop there. The show asks contestants to reveal their fears.
"You fill a form in about what you don't like ... I put frogs because I don't mind frogs. I did this challenge and they dumped a load of frogs on my head."
