G'day mate! Did you know we Aussies have the world’s longest fence? It’s called the Dingo Fence, or just the Dog Fence, and it stretches over 5,600 kilometers—that’s longer than the Great Wall of China! Built back in the 1880s, it was designed to keep those pesky dingoes away from our livestock in the southeast. The fence runs through Queensland, New South Wales, and South Australia, and it's a big part of our farming history. Quite the impressive bit of Aussie ingenuity, don’t ya think?
