Well, no Sir. I lived in PNG for 23 years and loved the place. Also lived and worked for some time on Cape York and Horn Island and that too was a beautiful part of Australia.
Apart from drinking at the Wongai and visiting the museum at the Gateway Torres Strait Resort, there really isn't anything else to do on Horn Island. A few sights to see on Thursday Island, less than one day. Visiting the outer islands requires Island Council approval and there are a few islands in the Straits one should avoid for a variety of reasons. Accommodation on the outer islands ranges from "problematic" and "difficult" to "impossible".
I'm talking about the coastal regions, Milne Bay and New Britain, not the highlands BTW.
Indeed, very beautiful parts of PNG. But without knowing the original poster's aviation experience, fraught with danger for the inexperienced or unwary.
Before venturing beyond Port Moresby any pilot with no PNG experience must obtain a very full and detailed briefing from an experienced PNG pilot or preferably take a current experienced PNG pilot with him. A lot of experienced PNG pilots have ended their careers in Milne Bay and New Britain, often due to sudden tropical weather patterns, resulting in rapidly diminishing options.
