When it comes to the unique natural wonders of Queensland, Australia, most people probably think of the Great Barrier Reef, one of the Seven Natural Wonders of the World. Few, however, know thatQueensland is also home to a place that is not only listed as a UNESCO World Heritage Site but also boasts extremely rare geographical landscapes and diverse flora and fauna, offering high value for both sightseeing and research — Fraser Island, the world’s largest sand island.

Fraser Island is an island entirely made of sand, covering a total area of 1,840 square kilometers — larger than three Singapores combined.Due to changes in Earth's temperature affecting sea levels, sand from the southeast was carried by the wind across the sea surface and settled on ancient volcanic rock dating back two million years. Over 700,000 years of accumulation, it formed what it is today. Now, the island features not only a stunning 75-mile-long beach, shifting sand dunes, and towering dunes hundreds of meters high, but also crystal-clear streams, perched lakes on the dunes, lush green sand dune rainforests, fantastical multicolored sandstone cliffs, and a unique ecosystem of flora and fauna... all of these natural wonders are so breathtakingly beautiful they take your breath away.

The wind not only carries sand to Fraser Island but also shapes its natural landscape. Dunes are the first creations of the wind on the island. When the top of a dune is blown away, creating a hollow, the wind then blows leaves and plants into the depression. The organic matter — known as coffee rock — formed by decaying plant material mixed with sand gradually fills the bottom of the hollow. Eventually, trapped rainwater cannot drain away, forming elevated perched lakes — the famous sand dune lakes known for their crystal-clear waters. Among them, Lake McKenzie is the most renowned perched lake on Fraser Island and a favorite among visitors. There are 42 perched lakes on the island, accounting for half of the world’s total.

The wind lifts the perched lakes onto the tops of the dunes and also carves out sandbanks in the rainforests. These sandbanks, transported by the wind, continuously encroach on the edges of ancient plant communities, moving as fast as one meter per year. Meanwhile, the plants at the edges of the sandbanks tenaciously defend their living space. Once the expansion of the sandbank slows, these plants quickly resume growth and survive tenaciously. When the sandbank stops moving, nutrients begin to accumulate, and the plants grow lush and thriving. Eventually, the sandbank transforms back into an oasis. Currently, there are 36 sandbanks on Fraser Island, making up the oldest and most complete sequence of sandbank systems in the world. The sandbanks on the eastern side of the island are active young dunes, while those in the sheltered central belt are entering a gradual greening stage.
