Oceania is traditionally understood as being composed of four regions: Australia, Melanesia, Micronesia, and Polynesia[10]. As with any region, however, interpretations vary; increasingly, geographers and scientists divide Oceania into Near Oceania and Remote Oceania.[11]
Most of Oceania consists of island nations comprising thousands of coral atolls and volcanic islands, with small human populations. Australia is the only continental country but Indonesia has land borders with Papua New Guinea, East Timor, and Malaysia. If the Australia-New Guinea continent is included then the highest point is Puncak Jaya in Papua at 4,884 m (16,024 ft) and the lowest point is Lake Eyre, Australia at 16 m (52 ft) below sea level.[citation needed]

Descriptions of the regions and constituents of Oceania vary according to source. The table below shows the subregions and countries of Oceania as broadly categorised according to the scheme for geographic subregions used by the United Nations.[8] The information shown follows sources in cross-referenced articles; where sources differ, provisos have been clearly indicated. These territories and regions are subject to various additional categorisations, of course, depending on the source and purpose of each description.
