Elliston District Council received the award for its reconciliation monument at the National Awards for Local Government in Canberra on June 19.
The council received the Promoting Indigenous Reconciliation Award for its Reconciliation Monument Wording project, which acknowledged the deaths of Aboriginal people at Waterloo Bay in 1849.
Elliston District Council chairman Kym Callaghan accepted the award and was joined by Jack Johncock, who was representing the Wirangu people.
The award acknowledges local government initiatives that promote recognition of Aboriginal and Torres Strait Islander people as the first inhabitants, their culture and history and their contributions to Australia.
Elliston was the only South Australian council awarded.
