Rick Trippe, from Darwin Australia, was out spearfishing when he was visited by a tiger shark yesterday at Bass Reef.
He did not feel threatened by the shark and reached out to touch its tale.
Feeling that the shark meant him no harm, he reached out again touching the 6ft shark.
Luckily the shark was passive.
Sharks are still wild and things can get hairy very quickly as this diver nearly found out.
