I have finally finished revising and updating my location guide for the Port Moresby and Bootless Bay area of Papua New Guinea.
Most divers traveling to PNG try to get through Port Moresby (which is still the only international gateway in to the country...) as quickly as possible because of its bad reputation for raskol gangs and random violence, but there is actually some excellent diving to be had.
Port Moresby is also not the hell-hole it is often depicted as - "gritty" and potentially dangerous yes, but manageable with a modicum of common sense in my opinion.
My guide provides an overview of Port Moresby, plus links to what else to do there and where to stay. There are overviews of diving in Port Moresby and the main dive sites, Loloata Dive Resort and my two favorite dive sites Suzie's Bommie and the wreck of the Pacific Gas.
