The Streaky Bay Jetty has been closed due to safety concerns, and will not be reopened until repair works have been completed.
The Department of Planning, Transport and Infrastructure stated there were key structural elements which were in an advanced state of deterioration and would require repairs.
The shelter, which is located next to the jetty, will be closed with repairs scheduled to proceed later in the year.
DPTI has stated the jetty would not be impacted by the closure.
The Department asks that the public take care around the site.
