Oceania is made up of 14 sovereign states, some of them relatively recently formed (1991). 99% of the territory is given by Australia, Papua New Guinea and New Zealand; the remaining nations are all small coral islands, with some exceptions given by islands of volcanic origin (Fiji, Solomon, Vanuatu, Samoa) and therefore much more extensive than the coral ones. Other islands controlled mainly by the United States and France are part of the continent.
The average altitude of the continent is consequently quite low (340 meters); however New Zealand and Papua New Guinea are rather mountainous regions. Major lakes and rivers are obviously found in Australia; the climate is generally tropical and equatorial, while in the interior parts of Australia it is scorching hot, in New Zealand there is a temperate climate.
