The following outline is provided as an overview and topical guide to Oceania.
Oceania is a geographical, and geopolitical, region consisting of numerous lands—mostly islands in the Pacific Ocean and vicinity. The term is also sometimes used to denote a continent comprising Australia and proximate Pacific islands.[1][2][3][4]
The boundaries of Oceania are defined in a number of ways. Most definitions include parts of Australasia such as Australia, New Zealand, and New Guinea, and parts of Maritime Southeast Asia.[5][6][7] Ethnologically, the islands of Oceania are divided into the subregions of Melanesia, Micronesia, and Polynesia.[8]
