I cant help but feel this is incredibly suspicious. Super vague details, but this is what I can gather (the website wont load for me, so this is just from the article)
-Only one Candidate will be chosen ("The successful applicant")
-There is no mention of food supply
-No mention of any form of entertainment media other than posting blogs/etc for the show
-No mention of any film or medical crew...last time I checked Australia is full of everything on earth that kills you. Box Jellyfish, Reef-Tip Sharks, Moray Eels, Razor sharp and poisonous coral, lion fish, barracuda...that's just in the water. Any native species of snakes, spiders, army ants, wild boars?
-No mention of survival gear of any kind, just housing. Knifes, firearms, spears?
-Are there cameras mounted around the island? Will you have any privacy at all, will this be later televised?
So do you have to be a survivalist to take this? It really starts to sound like some kind of weird psychological experiment. Six months is an incredibly long time to be all alone on an island in the pacific ocean.
I'm probably just paranoid and the website details a totally different skew, but oh well.
