The 27-year-old had seven out of the 12 “golden keys” on offer, one of which opened up a chest full of cash.
He defeated Real Estate Agent Natalia and HR Coordinator Julie to win the series, after the elimination Paula and Sean.
“I cannot believe that has just happened. I’m a millionaire! I’ve actually got a million dollars! This is the most spectacular moment of my entire life. My dreams have completely come true,” he said.
The finale, which stretched for more than two and a half hours, saw the final hour dominated by the opening of empty chests, until Mark hit pay dirt.
Only two other shows have given away a $1 million cash prize on Australian TV: Who Wants to Be a Millionaire? and Big Brother.
However Seven’s ambitious series, which many noted emulated Survivor, struggled in the ratings before moving timeslots several times. Some TV Tonight readers criticised episode length, casting, storytelling and gameplay.
But Seven’s knack for having a go with a new format should not be overlooked, strategically placed at the end of the year to minimise it’s knock-on effect.
