The 'Upside-Down Australia' meme is a long-standing internet joke based on the geographical fact that Australia is located in the Southern Hemisphere. Because maps traditionally place North at the top, internet users jokingly claim that everything in Australia—from people and animals to the text itself—must be physically upside down to prevent falling off the planet. This trope often involves flipping images 180 degrees or using 'upside-down' Unicode text generators to simulate the experience. It is a staple of global internet culture, frequently used to poke fun at Australian wildlife, weather, or simply to troll Australians in comment sections with inverted logic.
