Milne Bay is a province of Papua New Guinea. Its capital is Alotau. The province covers 14,345 km² of land and 252,990 km² of sea, within the province there are more than 600 islands, about 160 of which are inhabited. The province has about 276,000 inhabitants, speaking about 48 languages, most of which belong to the Eastern Malayo-Polynesian branch of the Austronesian language family. Economically the province is dependent upon tourism, oil palm, and gold mining on Misima Island; in addition to these larger industries there are many small-scale village projects in cocoa and copra cultivation. The World War II Battle of Milne Bay took place in the province. Culturally the Milne Bay region is sometimes referred to as "the Massim," a term originating from the name of Misima Island. Massim societies are usually characterized by matrilineal descent, elaborate mortuary sequences and complex systems of ritual exchange including the Kula ring. From island group to island group and even between close lying islands, the local culture changes remarkably. What is socially acceptable on one island may not be so on another. History The Milne Bay Province became a major base in World War II. The Australian Armed Forces operated HMAS Ladava base that won the Battle of Milne Bay in 1942. The US Navy built a large base in Milne Bay Province, Naval Base Milne Bay. Geography The coral reef systems of Milne Bay are some of the most biodiverse in the world, and as such attract equal attention from dive operators and conservation groups. The D'Entrecasteaux Islands still have volcanic activity, especially around Dobu and Fergusson Islands. The waters from the Amphlett group to the Trobriand Islands are poorly charted, and, as a result, are rarely visited by tourists or yachts passing through. On the other hand, the Louissiade Archipelago is a stopover for yachts travelling around the world and ones visiting from Australia,. However, the area sees few general tourists. The gold mine at Misima is no longer operational. Mining ended at Misima in 2001, with stockpile milling continuing into 2004. During its life, Misima has produced over 3.7Moz of gold and 18Moz of silver. Operations now are mainly focused on mine closure requirements and environmental rehabilitation. There is also on-going prospecting in Woodlark Island and Mwatebu, Normanby Island. Islands Islands in Milne Bay Province include: The D'Entrecasteaux Islands including Goodenough (Nidula), Fergusson (Moratau), Sanaroa, Dobu and Normanby
