Australia and Oceanian states, total number: 14.
The Australian continent is wholly owned by the country of the same name, the former British colony. All other states in the region are island countries. Relatively large amongst them are New Zealand and Papua New Guinea. All the other countries are small or microstates. Pacific ocean also holds a lot of islands, which are not independent, but considered to be a part of the UK, the U.S. or France. This is due to the desire of these countries to have naval bases or, for example, testing grounds for nuclear weapons.
