Craig is the mole.....(thoughts)
Being bored I did some research on Alexander Selkirk, the sailor mentioned in episode 1 that was abandoned on the island. Turns out his name at birth was Alexander Selcraig.
I'm no good with links but if you google the name Alexander Selcraig you will get tons on info telling you the same thing.
What other reason could there be for mentioning this guys name since they could have just said Robinson Crusoe.

In addition, look at the 2 clues given by ABC.
After going over the falls Craig said: The line pulls taut and just chokes me like a hanged man.
E_E_E_ = hangman
And the clue given to mobile users
NIC @ IT = NICATIT = TITANIC
On the boat on the way to the island Craig was at the very front with his arms stretched out just like in the Titanic movie.
