Kadina Airport (ICAO: YKDI) is a small general aviation airport located near Kadina, the largest town on South Australia's Yorke Peninsula. It serves private and charter flights, providing an air access point for a region primarily known for agriculture, mining heritage, and tourism. The airport is a relatively simple facility without scheduled commercial airline services, catering mainly to light aircraft, aerial agricultural operations, and private travel. It plays a practical role in connecting the Yorke Peninsula to other parts of South Australia given the region's distance from Adelaide. Kadina itself is the administrative centre of the Copper Coast council area, named after the historic copper mining industry that shaped the region in the nineteenth century. The airport supports regional connectivity for this rural community.
