The world's smallest continent is Australia. Despite being classified as a continent, it is often referred to as an island due to its isolation and the surrounding oceans. Australia is unique in terms of its diverse ecosystems, ranging from deserts and rainforests to coral reefs. Its distinct flora and fauna, such as marsupials and unique landscapes, contribute to its reputation as a biodiversity hotspot. The continent is also culturally significant, with a rich history of Indigenous peoples alongside its colonial heritage.
