Cummins and Port Lincoln have both been nominated for the inaugural South Australian Ag Town of the Year Award.
Other Eyre Peninsula towns nominated for the award include Cleve, Cowell, Kimba, Wudinna and Minnipa.
Cummins was nominated for its role as a service centre for dryland cropping and livestock production and as a hub for surrounding districts.
Lower Eyre Peninsula District Council mayor Jo-Anne Quigley said Cummins prided itself on its resilience and social capital.
"In the heart of the Lower Eyre Peninsula broad-acre farming region, the 700 residents provide a service centre for dryland cropping and livestock production," she said.
"Locals know vibrant communities don't just happen - they need passion, innovation and investment."
Member for Flinders Peter Treloar said Cummins was a hub for surrounding communities with four machinery dealerships and four major agricultural supply businesses, and was home to volunteers passionate about improving the town.
Port Lincoln has been nominated for being a central hub for agriculture and being at the forefront of research and sustainability for the fishing industry.
Primary Industries Minister Tim Whetstone said the winner would be a town that had demonstrated excellence and support for its farming industries over the past 12 months, and will be chosen by an independent panel.
Five finalists will be named before the winner is announced at the Regional Showcase.
