Jetty Towns of the Gulf

A slower coast on the Spencer Gulf side

By Discover Eyre Peninsula · 10 June 2026 · 6 min read

On the sheltered eastern shore, life still gathers around the jetty. From Cowell to Arno Bay, these gulf towns move to the rhythm of the tide and the evening catch.

The other coast

The Eyre Peninsula's wild west coast gets the postcards, but its eastern, gulf-facing shore keeps a gentler rhythm. Here the Spencer Gulf is calm and shallow, and life in the small towns still gathers around the jetty, that simple finger of timber reaching out over the water where everyone eventually ends up.

Cowell and the harbour

Cowell sits beside Franklin Harbour, a near-enclosed lagoon famous for blue swimmer crabs and oysters. The jetty fills with anglers at dusk, dropping lines for whiting and squid, while kids leap from the pylons into the warm shallows. It is unhurried in the best way, a town that has not forgotten how to do nothing well.

The estuary at Arno Bay

Further south, Arno Bay folds a tidal estuary behind its dunes, and a boardwalk loops through mangroves alive with small fish and birds. The estuary is the gulf's nursery, where the next generation of fish grows up among the roots, and walking it at low tide you understand how the whole system fits together.

The evening ritual

What ties these towns together is the evening. As the sun drops over the gulf, the jetties fill, the rods come out, and the day's tension drains away into the still water. You do not need to catch anything. The point, as any local will tell you, is simply to be there when the light goes gold.
