Aussie reality TV veteran David Genat is living it up on “Deal or No Deal Island” … and he’s dishing on why he hopped over to the U.S. to try to chase down “the biggest prize in TV history!”

David — AKA “The Golden God” — spilled the tea on the “Big Down Under” podcast … saying getting paid to live it up in Fiji and compete for a jaw-dropping $10M prize is pretty much the ultimate reality gig!

David also dishes on how this show blows “American Survivor” out of the water, pointing out its $1M prize barely registers after Uncle Sam takes his cut … especially after “going through hell” to win the show.

But don’t get it twisted — it’s equal parts fun and games, because David makes it clear he still got the full high-stakes experience of strategy and social gameplay he’s so good at!
