Museum
The South Australian Museum (http://www.samuseum.sa.go...) in Adelaide has an excellent exhibit on Papua New Guinea that includes many historical artifacts and good documentation and reports from the early missionaries that worked among the PNG tribes.
Read
There are many great books about Papua New Guinea, including great fiction as well as non-fiction. An excellent book for the general reader about Papua New Guinea is Sean Dorney's Papua New Guinea: People, Politics, and History Since 1975. The third edition is the best, but it is pretty hard to find outside of Australia and is not that easy to find there.
John Laurel Ryan, a former employee of the Australian Broadcasting Corporation ABC, also wrote an excellent book, "The Hot Land" which was published about 1970. Among other fascinating historical information it contains accounts of various manifestations of cargo cult, John Teosin's "baby garden" on Buka Island, and eye-witness reports that have been rigidly suppressed in other media about the Indonesian takeover of what was formerly Dutch West Papua. This excellent and at times disturbing book will also be hard to find, and sadly its author even harder!
There is also a lot of anthropological work that has been done in Papua New Guinea leading some to term the area an "anthropologist's laboratory", which can contribute greatly to an understanding of the different groups in the region. Some of the more accessible volumes include Malinowski's "Argonauts of the Western Pacific", centred on the Trobriand Islanders, living just north of Papua New Guinea itself; Reading the skin - Michael O'Hanlon; Coaxing the spirits to dance - Welsch, Webb et al; The Art of Kula - SF Campbell; Inalienable Possessions - AB Weiner.
Understand
There is evidence of human settlement as long ago as 35,000 years in what is now Papua New Guinea. This comes from an archaeological site at Matenkupkum, just south of Namatanai in New Ireland province. Other archaeological digs at several locations in New Ireland have discovered tools and food residue dating back 20,000 years.
In more modern times, Papua New Guinea known popularly as 'PNG', the eastern half of the island of New Guinea which is the second largest island in the world, was divided between Germany 'German New Guinea' and Great Britain 'British Papua' in 1884. The Dutch had West Papua, now the Indonesian territory of Papua. The southeast part of the island, also known as Papua, was owned by the UK but administered by Australia, and thus a colony of a colony, until Australian independence in 1901, when it became an Australian colony. In 1914, the Australians did their part in the Allied war effort and took control of German New Guinea, and continued to administer it as a Trust Territory under the League of Nations and later the United Nations. However, it was not just disinterested colonialism. Gold had been discovered in several places and was rapidly exploited. Remnants of vast gold dredges can still be seen in the Bulolo and Wau area.
During World War II, New Guinea was the site of fierce fighting on land at Buin and on the Kokoda Track and sea at the Battle of the Coral Sea. It was the first place in the war where the Japanese advance was checked and then reversed. After the war, both New Guinea and Papua were administered from the government center of Port Moresby on the south coast, in Papua. In 1975, the country, now united as 'Papua New Guinea', achieved independence from Australia. Today Papua New Guinea continues to be the foremost country in Melanesia. The country struggles to fulfill the dreams of independence as economic stagnation, corruption, law and order problems, and a nine-year secessionist revolt on the island of Bougainville all conspire to make the country somewhat less than a tropical paradise.
The attempts by Bouganville to break away at the time of Independence led to a decision to offer the regions of the country a certain amount of political autonomy. Decentralization led to the establishment of nineteen provincial governments and the process of dividing up the country into unviable administrative units seems to be continuing, with a decision in 2009 to split both Southern Higlands and Western Highlands provinces into three new provinces.
In 2009, Papua New Guinea received 125,000 visitors, but only around 20% of these declared themselves as tourists. The country offers the traveler a true paradox. With little tourist infrastructure outside the main tourist areas, getting around can be tough. But Papua New Guineans themselves are wonderfully welcoming people who will go to great lengths to accommodate strangers. Tourism is well developed and growing in a handful of locations. Beyond these, the country is 120% adventure travel and not for the inexperienced or faint of heart.
For people who can make it out here, the experience is unforgettable. The incredible natural beauty is simply indescribable. Its unique flora and fauna includes enormous radiations of marsupials and birds, including the Raggiana bird-of-paradise the national symbol and several species of tree kangaroos. Untouched coral reefs compete with spectacular World War II wrecks for the attention of divers, and the hiking is out of this world.
With rugged terrain, inter-tribal mistrust, and diverse languages, intermarriage between the peoples has, until recently, been very limited. Physical and facial appearance varies significantly throughout the country; from those who look almost Polynesian in some coastal areas, through the short, stocky Highlanders, to the tall and statuesque people of the area around Rabaul in New Britain and the dark-skinned inhabitants of Bouganville, who could almost come from Africa.
The central highlands of Papua New Guinea were not mapped until the 1930s and not effectively brought under government control until the late 1960s. As a result, the people are as interesting as the geography, flora, and fauna. Papua New Guinea is a place that often markets itself as 'the Last Unknown' or a place where you can still find 'Stone Age People'. Of course, telling a Papua New Guinean that you consider them a stone age savage is incredibly rude. While you can, if you try hard enough, find old men who remember the first time they or anyone in their society saw metal, you'll also have trouble finding anyone who has not seen Titanic. Indeed, what makes Papua New Guinea so interesting today is not the fact that it is some sort of living museum, but its incredible dynamism. In the hundred-year shift from stone to steel to silicon, Papua New Guineans have turned the shortest learning curve in human history into one of the most colorful, and often idiosyncratic, experiments in modernity ever produced by human beings. Featuring ritual garb made of human hair and rolled up Instant Noodle wrappers, rap in Pidgin English, or tribal warriors named 'Rambo' for their valor in combat, Papua New Guinea's collision with global culture has been intense and fascinating. So don't worry about the fate of 'traditional culture': in the bar room brawl between Papua New Guinea and the global culture industry the biggest worry is keeping Papua New Guinea from pummeling global culture to a pulp.
Terrain
The country is situated on the Pacific Ring of Fire, at the point of collision of several tectonic plates. There are a number of active volcanoes, and eruptions are frequent. Earthquakes are relatively common, sometimes accompanied by tsunamis.
The country's geography is diverse and, in places, extremely rugged. A spine of mountains, the New Guinea Highlands, runs the length of the island of New Guinea, forming a populous highlands region mostly covered with tropical rainforest. Dense rainforests can be found in the lowland and coastal areas as well as very large wetland areas surrounding the Sepik and Fly rivers. This terrain has made it difficult for the country to develop transportation infrastructure. In some areas, airplanes are the only mode of transport. The highest peak is Mount Wilhelm at 4,509 metres 14,793 ft. Papua New Guinea is surrounded by coral reefs which are under close watch to preserve them.
