A South Australian businessman is kitting out his bomb shelter in the Adelaide Hills in preparation for a potential rogue missile strike.
Nathan Stewart is taking the North Korean threat very seriously, as Kim Jong-un flexes his nuclear muscle.
Although it's unlikely the North Korean dictator has Stewart's Bugle Ranges property in his sights, Stewart says he will be prepared if Armageddon comes, hiding out in his own personal bunker.
The bunker was once owned by Hugh Bonython of the Bonython dynasty.
"It was built to withstand a nuclear attack," Stewart says. "It's the real deal."
The bunker features steel doors, concrete walls and above-ground air vents, with a generator that Stewart believes can keep him going underground for months if needed.
If the threat of nuclear devastation never eventuates, Stewart does have an alternative plan for his bunker.
"Potentially it'll be a boy's room where you can play eight ball," he says.
"Probably use the Bonython billiard table and just have it as a chilled place."
