Adelaide International Airport — Adelaide, Australia

Adelaide International Airport serves South Australia's capital and largest city, sitting close to the coast at just 20 feet above sea level with two runways handling both international long-haul routes and the dense schedule of domestic flights connecting Adelaide to Melbourne, Sydney, and Perth. The airport lies only a few miles from Adelaide's compact city center, giving it one of the shorter airport-to-downtown commutes among Australia's state capitals. South Australia's economy leans on wine production, mining, and defense manufacturing, and the airport's cargo operations reflect exports tied to the Barossa Valley and other nearby wine regions alongside mineral shipments from the state's interior. Adelaide itself was laid out in the 19th century according to a formal city plan with distinctive parklands ringing the center, giving it a more orderly grid than many other Australian cities. International services from Adelaide tend to focus on Asian and Middle Eastern connections rather than the wider long-haul network available from Sydney or Melbourne, reflecting the city's smaller population base. For South Australians, the airport represents the state's only significant international departure point, making it central to both business and holiday travel planning across the region.
