Climate map of Australia

Climate of Oceania Many of the Pacific Islands have a tropical climate due to their location near the Equator and warm ocean currents

Great Barrier Reef Located off of Australia’s northeast coast, the Great Barrier Reef is often called the world’s largest coral reef Some 400 species of coral are found here

Australia in isolation Because of Australia’s location and its island status, the plant and animal species of Australia grew in relative isolation Tectonic stability and an unusual pattern of climate change also have contributed This has created many varieties of plants and animals found only in Australia
