If you have never heard of Oceania then you have most definitely been missing out on one of the greatest seas around the world. Oceania is a large geographic area that includes Australia, Melanesia, Polynesia and Tonga. With an area of over 7,000 square kilometers, Oceania contains a land mass of nearly 8,000,000 square kilometers and a total population of more than 41 million people. One of the most interesting things about Oceania is that it is composed of three main islands: The Fiji Islands, Easter Islands, and Tahiti. While some people may be turned off by the thought of visiting such a large sea in order to witness its beauty, there are actually many benefits to be found from visiting Oceania.
