An orthographic projection of Oceania
Oceania ( OH -s(h)ee-AH -nee-ə, -AY - , OH -shee-A(H)N -ee-ə ) is a geographical region comprising Australasia , Melanesia , Micronesia , and Polynesia . Spanning the Eastern and Western Hemispheres , at the centre of the water hemisphere , Oceania is estimated to have a land area of about 9,000,000 square kilometres (3,500,000 sq mi) and a population of around 44.4 million as of 2022. When compared to the other continents, Oceania is the smallest in land area and the second-least populated after Antarctica .
Oceania has a diverse mix of economies from the highly developed and globally competitive financial markets of Australia , French Polynesia , Hawaii , New Caledonia , and New Zealand , which rank high in quality of life and Human Development Index , to the much less developed economies of Kiribati , Papua New Guinea , Tuvalu , Vanuatu , and Western New Guinea , while also including medium-sized economies of Pacific islands such as Fiji , Palau , and Tonga . The largest and most populous country in Oceania is Australia, and the largest city is Sydney. Puncak Jaya in Highland Papua , Indonesia , is the highest peak in Oceania at 4,884 m (16,024 ft).
The arrival of European settlers in subsequent centuries resulted in a significant alteration in the social and political landscape of Oceania. The Pacific theatre saw major action during the First World War with the Japanese occupying many German territories. During the Second World War , Allied powers the United States , Philippines (a U.S. Commonwealth at the time) and Australia fought against Axis power Japan across various locations in Oceania.

Bougainville and neighbouring islands
Bougainville Island (Tok Pisin : Bogenvil ) is the main island of the Autonomous Region of Bougainville , which is part of Papua New Guinea . Its land area is 9,300 km2 (3,600 sq mi). The population of the whole province, including nearby islets such as the Carterets , is approximately 300,000 (2019 census). The highest point is Mount Balbi , on the main island, at 2,715 m (8,907 ft).
The much smaller
Buka Island ,
c. 500 km2 (190 sq mi) , lies to the north, across the 400–500 m (1,300–1,600 ft) wide
Buka Strait . Even though the strait is narrow, there is no bridge across it, but there is a regular ferry service between the key settlements on either side. The main airstrip in the north is in the town of Buka. Buka has an outcropping that is 175 km (109 mi) from
New Ireland . Among the large islands of Papua New Guinea, New Ireland is the closest to Buka. (

Moai facing inland at Ahu Tongariki , restored by Chilean archaeologist Claudio Cristino in the 1990s
Moai or moʻai ( MOH -eye ; Spanish : moái ; Rapa Nui : moʻai , lit. 'statue') are monolithic human figures carved by the Rapa Nui people on Rapa Nui (Easter Island) in eastern Polynesia between the years 1250 and 1500. Nearly half are still at Rano Raraku , the main moai quarry, but hundreds were transported from there and set on stone platforms called ahu around the island's perimeter. Almost all moai have overly large heads, which account for three-eighths of the size of the whole statue. They also have no legs. The moai are chiefly the living faces (aringa ora ) of deified ancestors (aringa ora ata tepuna ).
The statues still gazed inland across their clan lands
when Europeans first visited the island in 1722 , but all of them had fallen by the latter part of the 19th century. The moai were toppled in the late 18th and early 19th centuries, possibly as a result of European contact or
internecine tribal wars . (
