Australian Expeditions refer to various journeys and explorations undertaken in Australia, often aimed at discovering new lands, resources, or scientific knowledge. Notable expeditions include those led by Matthew Flinders, who mapped the Australian coastline in the early 1800s, and Robert O'Hara Burke and William Wills, who famously attempted to cross Australia from south to north in 1860. These expeditions have significantly contributed to the understanding of Australia's geography, flora, and fauna. They also played a crucial role in the development of Australian history and culture, highlighting the challenges faced by explorers in the vast and diverse landscapes of the continent.
