Countries of Oceania.

Oceania is the smallest continent by land area yet one of the most geographically dispersed, comprising 14 sovereign states scattered across roughly one-third of the Earth's surface in the Pacific Ocean. The region stretches from the vast landmass of Australia — a continent in its own right — to tiny coral atolls like Tuvalu and Nauru, some of the smallest nations on Earth. Despite its modest land area of about 8.5 million square kilometres (most of it Australia), Oceania's maritime territory is immense, covering over 100 million square kilometres of ocean.

Oceania is conventionally divided into four subregions. Australasia includes Australia and New Zealand, the two largest and most economically developed nations. Melanesia encompasses Papua New Guinea (home to over 800 languages — more than any other country), Fiji, Solomon Islands and Vanuatu. Micronesia includes the Federated States of Micronesia, Kiribati, Marshall Islands, Nauru and Palau. Polynesia stretches across the eastern Pacific and includes Samoa, Tonga and Tuvalu.

The linguistic diversity of Oceania is extraordinary. The Austronesian language family dominates, with Polynesian languages (Samoan, Tongan, Maori) forming one branch and Melanesian languages forming another. Many countries have adopted English or French as official languages alongside their indigenous tongues. New Zealand is officially known as Aotearoa in Maori, Fiji calls itself Viti in Fijian, and Palau uses the name Belau.
