There's a whole line of Karawa taxi's around the side at the official taxi rank so not sure where this news article got its information from!

The problem is that apart from one or two signs, you don't always see the taxi rank, especially if you were new to the place therefore the illegal guys have a free pass at those coming out the door! Hopefully the new airport will have them parked right outside the door that way the illegal guys will have nowhere to go!
