Melbourne Avalon International Airport — Geelong/Melbourne, Australia

Melbourne Avalon International Airport sits between Geelong and Melbourne in the Australian state of Victoria, offering an alternative to the city's much larger main airport. The field is a mere 35 feet above sea level; a single long runway handles both commercial jets and larger military aircraft. The airport has long served as the home of the Australian International Airshow, a major biennial event drawing aviation enthusiasts, military delegations, and aircraft manufacturers from around the world. Low-cost carriers have periodically used Avalon as a base for domestic and limited international routes, positioning it as a budget-friendly alternative to Melbourne's primary gateway. Its location roughly midway between Geelong and central Melbourne makes it more convenient for travelers from the surrounding Geelong region than for those based in the city center. Although it has only one runway, Melbourne Avalon International Airport retains the capacity to handle sizable passenger jets, a legacy of its dual civilian and airshow-driven function.
