There is no precise definition of the exact range of the region, which may include at a minimum of three subregions of Polynesia, Micronesia and Melanesia, or the entire region between the Americas and Asia, which includes Australasia and the Malay Archipelago. Many also use the term Oceania to refer to Australia and its nearby islands.

The wider Oceania has an estimated population of 38.82 million in 2014. The narrower definition that includes Micronesia, Island Melanesia, and Polynesia (not New Zealand) has a population estimated at 6 million in 2014. The total population of Oceania minus mainland Australia is about 18 million.

Is Oceania a Continent?

No, Oceania is not a continent. It is a region of island territories located west of South America and east of Australia. There are four main sub-regions in Oceania.


This is an Oceania region that covers New Zealand, Australia, and its surrounding islands. The area has a population of 39 million people. The term Australasia was coined in 1756 by a French writer called Charles de Brosses. The total population in this area is about 33 million people.

Interestingly, this Oceania region's landmasses were once part of the [ancient Gondwana continent[(https://www.newworldencyclopedia.org/entry/Gondwana).


This is a region in Oceania between Fiji and Papua New Guinea. Melanesia covers a landmass of 1 million square kilometres with 2,000 islands and 12 million inhabitants. Some independent nations covered under this oceanic region include the Solomon Islands, Vanuatu, Papua New Guinea and Fiji.

It is believed that humans have inhabited the area for thousands of years. The first people to settle in the region migrated from Indonesia and brought the early forms of agriculture. They were followed by people from Taiwan who had seafaring skills.

The word "Melanesia" comes from a Greek word that means" black Island." This is because the local inhabitants had a black skin tone.

Documented history shows that the different communities in this oceanic region had trade relations and were politically integrated over 3,500 years ago. The common form of trade included the exchange of obsidian and shell ornaments.

Traditionally, the social standing of Melanesian society depended on the amount of wealth an individual or family could amass.


This sub-region of Oceania is located in the western part of the Pacific Ocean and comprises over 600 islands. The countries found on this Island include the Republic of the Marshall Islands and the Republic of Palau. The United States even administered these two countries, including the Northern Marina as the Pacific Islands Trust Territory, between 1947 and 1986.

Micronesia covers a total landmass of 271 square miles and has a population size of 534,000 people. The climate of this region is tropical, with an annual temperature of below 27°C with slight seasonal variation in temperature. There are distinct dry and rainy seasons, with the dry months occurring between December and April.


This is a sub-region of Oceania that covers over 100 islands in the southern and central of the Pacific Ocean. The word Polynesia is derived from a Greek word that means "many islands." The original inhabitants of the area were called Polynesians, and they were expert navigators and sailors. This oceanic region borders New Zealand to the south Eastern Island and Hawaii to the north.

Out of six million residents of Polynesia, the native Polynesians are about three million. A distinct trait of the Polynesians is that they have lighter skin and are tall. They also have dark hair that's either wavy or straight but not curled.
