Cairns International Airport — Cairns, Australia

As the aerial doorway to the Great Barrier Reef and the rainforests of Tropical North Queensland, CNS has grown from a modest regional strip into one of Australia's most important tourism-driven airports, welcoming international visitors bound for reef diving trips, Daintree rainforest tours, and the mountain village of Kuranda accessible by scenic railway or cableway. A long main runway extends out over reclaimed land close to the Coral Sea, capable of handling wide-body jets on long-haul international services, while a shorter secondary strip absorbs general aviation and light charter traffic. Japanese tourists formed the backbone of the airport's international arrivals during the boom years of the 1980s and 1990s, a pattern that has since diversified toward other Asian, European, and domestic Australian markets as the reef's global reputation has grown. Cruise ships calling at the adjacent port add another stream of visitors passing through a city almost entirely built around tourism, making the airport a critical economic engine for the entire far-north Queensland region.
