Wobbegongs are not known for their attacks. They're better known as "hake" when they're encased in batter and deep fried. You really have to work at getting attacked by a wobbegong, almost to the point where you have to kick one in the face to make it bite you. People generally don't report wobbegong attacks. It's almost as embarrassing as being trapped in a wombat hole when the wombat presses its bum up against the roof and crushes you.
Australia is that kind of place.
