Australia and New Zealand have flora and fauna that are found nowhere else on Earth. Australia is distinctive because it is an island, a country, and a continent—the smallest of the world’s continents. No other land mass can concomitantly make those three claims. Australia consists of a large mainland and the island of Tasmania to the south. The main physical area of New Zealand, on the other hand, consists of two main islands separated from Australia’s southeastern region by the Tasman Sea. Australia is surrounded by various seas.
