Density is where area and population interact, and it often reverses the impression the headline figures give — a large country with a small population can feel emptier than a small crowded one by an enormous margin. ## Practical differences - They drive on opposite sides — Australia on the left, United States on the right. - Different currencies: the Australian dollar and the United States dollar. - United States spans 6 time zones, so "local time" there is not a single answer. - Different continents — Oceania and North America. ## Australia The sixth-largest country in the world and the only one that covers an entire continent. The Great Barrier Reef runs about 2,300 km and is the largest structure made by living organisms on Earth, visible from orbit. Around eighty percent of its mammals, reptiles and flowering plants exist nowhere else. Melbourne and Sydney are within roughly a hundred thousand people of each other, and which counts as the largest city depends on where the boundary is drawn. ## United States Third or fourth largest country in the world depending on how China's area is counted. It spans six standard time zones across the fifty states, from UTC-10 in Hawaii to UTC-5 on the east coast. Death Valley holds the highest reliably recorded air temperature on Earth, 56.7 °C in 1913, and is 86 m below sea level; Denali, 5,500 km away in Alaska, is 6,190 m. > Neutral facts only. Nothing here addresses politics, government, economics or which country is preferable in any respect — population is the one figure that dates, and it carries its year. ## Common questions ### Is Australia bigger than United States?
