When is Papua New Guinean Independence Day?

Independence Day is a public holiday in Papua New Guinea observed on September 16th.

This is the National Day of Papua New Guinea and commemorates independence from Australia on September 16th 1975.

History of Papua New Guinean Independence Day

Papua New Guinea occupies the eastern half of the island of New Guinea and its offshore islands in the southwestern Pacific Ocean.

The region was first visited by Portuguese and Spanish explorers in the first half of the sixteenth century. They didn't establish any notable colonies, but gave the island its name and ports on the island became important staging posts for fishing expeditions.

The Spanish named the island ' New Guinea' as the inhabitants reminded them of the people of Guinea in West Africa.

In 1884, Britain established the protectorate of British New Guinea over the south-eastern part of New Guinea, while Germany annexed the north-eastern part of the island.

In 1906 control of British New Guinea was transferred to the newly independent Commonwealth of Australia and renamed Territory of Papua.

At the onset of the First World war, Australian troops occupied German New Guinea. Following Germany's defeat, the League of Nations granted Australia a mandate to run German New Guinea, albeit separately from the Territory of Papua.

The two territories only joined together as the Territory of Papua and New Guinea in July 1949 after the whole of New Guinea had been occupied by the Japanese during the Second World War.
