Members of the Clare Valley Flying Group have pitched plans to upgrade the aerodrome. The group is seeking a federal government grant to seal and add lighting to its runway.
Senator Simon Birmingham listened to president Dave Willson last week in Watervale, who explained the importance of the upgrade and how it would potentially benefit SA.
The group have submitted an application seeking $833,256 from the federal government.
The project is estimated to cost about $943,000 and has already received the support of the Clare and Gilbert Valleys Council.
Clare Valley Flying Group treasurer Tony Smith said the upgrade would have benefits for not only the aerodrome, but for the local farmers and tourism companies who use the facility.
He said the upgrade would allow planes to land safely all year round, increasing productivity for farmers, greater access to flight schools and encouraging tourists from interstate.
