OCEANIA, the smallest continent, is one of the most diverse and fascinating areas on the planet. A large percentage of geography experts now consider the long-established continent of Australia to be more accurately defined as Australia/Oceania. Collectively it then combines all of Australia, New Zealand, Papua New Guinea, as well as the thousands of coral atolls and volcanic islands of the South Pacific Ocean, including the Melanesia and Polynesia groups. Oceania also includes Micronesia, a widely scattered group of islands that run along the northern and southern edges of the Equator.
