Whyalla City Council has had to close the Point Lowly marina dock from public use in the interest of community safety.
Recent underwater surveys have found it to be an unsafe condition.
The Council is currently evaluating repair costs and they will provide more detail on the next steps as soon as possible.
Whyalla City Council has appologised for any inconvenience.
Should you have any queries, please contact the Council on 8640 3444.
