Smithton Airport — , Australia

Smithton Airport, coded SIO, is located in the northwestern corner of Tasmania, Australia, serving the town of Smithton and the surrounding Circular Head region. The airport primarily supports general aviation, agricultural flights, and occasional charter services rather than scheduled airline routes. Smithton's economy centers on dairy farming, forestry, and vegetable production, and SIO provides an important transport link for this relatively isolated part of Tasmania's coastline. The region is also known for its rugged coastal scenery and proximity to notable natural landmarks. While modest in scale, SIO remains a valued piece of local infrastructure, supporting emergency access and light aviation activity across Tasmania's remote northwest.
