Did you know that Australia is home to the world's longest fence? Stretching over 5,614 kilometers (3,488 miles), the Dingo Fence, also known as the Dog Fence, runs across the continent from the eastern coast of Queensland to the cliffs of the Nullarbor Plain in South Australia. Originally constructed in the 1880s to keep dingoes away from fertile land, it now serves as a barrier to protect livestock from wild dogs and other predators. This incredible feat of engineering is longer than the Great Wall of China and can be seen as a testament to Australia's unique wildlife and dedication to preserving its natural resources.
