Cowell
A quiet east-coast town with a celebrated oyster lease and the largest jade deposit in the southern hemisphere.
Oysters, jade and a sheltered harbour
Cowell sits on Franklin Harbour, an almost landlocked bay on the eastern Eyre Peninsula whose calm, tidal waters connect to Spencer Gulf through a channel only about 100 metres wide. Those conditions are ideal for aquaculture, and Cowell is one of the best places on the peninsula to taste locally farmed oysters. The town also sits within the Cowell Jade Province, one of the largest known nephrite jade deposits in the world, after jade was discovered in the nearby Minbrie Ranges in 1965.
A heritage town on the Lincoln Highway
Proclaimed in 1880, Cowell keeps an unhurried, heritage feel along its main street. The Franklin Harbour Historical Museum, housed in the former post office and postmaster's residence, gathers local history, geological specimens and artefacts from the district.
What visitors do
Days here are spent fishing and crabbing from the town jetty, walking the foreshore, and exploring the calm harbour. Nearby are the safe swimming beach at Lucky Bay, the historic coast around Port Gibbon, the Arno Bay foreshore and estuary, and the inland mallee scenery of Lake Gilles Conservation Park.
