Australia is full of jaw-dropping facts. It’s the only country that’s also a continent. The Great Barrier Reef is the largest living structure on Earth and visible from space. Lake Hillier is bubblegum-pink, and no one’s entirely sure why. Australia’s snowy mountains get more snow than Switzerland. The Dingo Fence, built to keep wild dogs out, stretches over 5,600 kilometers—longer than the Great Wall of China. Uluru, a sacred rock, changes color at sunrise and sunset. Nearly 90% of Australia’s animals exist nowhere else. At night, the skies reveal some of the clearest views of the Milky Way.
