The councils of Port Adelaide Enfield and Charles Sturt both provide historical information on their websites about Kaurna people collecting shellfish from the Port River and surrounding areas.
Uncle Lewis O’Brien in the Mudlangga to Yertabulti Track (Port Adelaide Enfield) writes the following:
“For thousands of years Kaurna people had summer camps along the Port waterways and beaches and fed on fish, crabs and oysters.”
Yerta Bulti (Charles Sturt) describes the river and estuarine environment which provided such abundant food sources for the Kaurna people and shows a photo of a Kaurna midden with discarded shells, discovered in 2011 during construction of NewPort Quays.
