Natural Landmarks in Australia

Australia, the world’s sixth-largest country, is a land of geographical extremes, with landscapes ranging from arid deserts to lush rainforests, towering mountains, and extensive coastlines. The country spans over 7.6 million square kilometers, making it the smallest continent but the largest island on Earth. Australia’s geography is diverse, shaped by ancient tectonic activity, vast deserts, and unique ecosystems that have evolved in isolation for millions of years. The country’s interior, often referred to as the Outback, is dominated by dry, arid regions, while its coastal areas are lined with lush rainforests, rugged cliffs, and world-famous coral reefs. Australia’s isolation has also contributed to its distinct wildlife, home to many species found nowhere else on Earth. From towering rock formations to pristine marine environments, Australia’s natural landmarks offer a rich tapestry of landscapes that reflect its geological and ecological diversity.
