What we call Oceania is technically not a continent. It is actually a collection of islands rather than landmasses. Australia is in fact a continent and contains not only the country which shares its name, but also New Guinea and the surrounding islands. Perhaps surprisingly New Zealand is not a part of the Australian continent, but is on a separate, submerged continent called Zealandia!
Because of the region's nature as many collections of islands, for convenience's sake they have been grouped together under the name Oceania. Opinions as to which lands are a part of Oceania differ, with some using it only for the smaller islands (discounting Australia and New Zealand) whilst others include the Philippines and Indonesia, which are more traditionally thought of as parts of Asia.
For the purposes of this quiz the term Oceania refers to the Australian continent, the Zealandia continent, the island groups of Polynesia, Melanesia and Micronesia, and the countries which are found upon them.
