Oceania is a region made up of thousands of islands throughout the Central and South Pacific oceans. It includes the continental islands of Australia (the smallest continent in terms of total land area), New Zealand, and Papua New Guinea. The name “Oceania” justly establishes the Pacific Ocean as the defining characteristic of the continent. Most of Oceania is under the Pacific( a vast body of water that is the largest than all the Earth’s continental landmasses and islands combined.)
