Fraser Island is the world's largest sand island and a UNESCO World Heritage Site. It is popular throughout the seasons and has large visiting numbers of both tourists and locals all year round. Among the reasons that people love to visit, apart from the 250 km wide sand beaches, are the beautiful sand cliffs, the pristine blue seas, dune lakes, lush marine life as well as the tall rainforests among the sand, something you wouldn't expect to find in an area that resembles an arid desert. Fraser Island should be top on your list.
