I don't think it will ever be.
PNG diving was already known 30 years ago when nobody could put any dive site of Indonesia on the map except for Bali, Bunaken and Maumere (weirdly enough Maumere was a big name in diving Indonesia before 92, thanks to Rudie Kuiter ), Raja 4 wasn't even heard about and look at the situation now.
On the marketing side , I don't give PNG a chance to develop like Indonesia :
- Tell the americans about the safety situation and how raskols can get into a resort anytime they like.
- Make sure the russians know there is no shopping possible around.
- Let the chinese acknowledge they can't expect asian food diet in the islands nor karaoke.
What is there left? Too far away and expensive for cheap europeans, the SP beer is too bitter and too less for ozzies.
It’s funny because it’s true.
