Australia vs Usa True Size Comparison: Visual Overlay and Hard Numbers
By Elena Rostova
Comparing continental land area requires stripping out foreign territories and non-contiguous states. When analysts measure the lower 48 states against mainland Australia and Tasmania, the geographic size comparison becomes an almost dead heat.
The total land area of the contiguous United States covers approximately 2,954,841 square miles (7.65 million square kilometers). Adding inland water bodies brings that figure to roughly 3,119,884 square miles (8.08 million square kilometers).
According to official survey figures from Geoscience Australia, the Australian landmass covers 2,968,464 square miles (7.69 million square kilometers). If you exclude American rivers, reservoirs, and the Great Lakes, Australia’s dry land surface is actually slightly larger than the dry landmass of the lower 48 states.
Driving coast-to-coast illustrates the scale. A road trip from Sydney on the Pacific Coast to Perth on the Indian Ocean covers approximately 2,445 miles (3,935 kilometers) along the Great Eastern Highway and Eyre Highway. That distance mirrors a cross-country drive from New York City to Los Angeles (roughly 2,790 miles). Crossing Australia from north to south, from Darwin to Adelaide, demands a 1,880-mile trek down the Stuart Highway, comparable to driving from Minneapolis down to the southern tip of Texas.
