Great Barrier Reef, Cairns

Many thanks to my little brother Kevin Zheng who sent me this beautiful postcard during his trip in Australia this Chinese New Year holidays. Great Barrier Reef, which is a UNESCO World Heritage Site since 1981, is the world's largest coral reef system located in the Coral Sea, off the coast of Queensland, Australia. Kevin even got the cute postage paid mark in the post office of the Green Island for me.
