If this aerial view of the Great Barrier Reef is a reminder that you ❤ everything Australia, today's your day. Australia Day commemorates January 26, 1788, when the first transplants from England said g'day to Australian shores, but you can just call it a day to celebrate all things Aussie. From the Barrier Reef to the rugged bush to the dry Outback, we invite you to join the diverse people of Oz in celebrating their island nation (well, we can almost join the Aussies—it's tomorrow for them already, so they celebrated yesterday). © Peter Adams/Offset by Shutterstock Reproduced from https://www.bing.com/search?q=great+barrier+reef&form=hpcapt&filters=HpDate:%2220210126_0800%22 The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.
