It appears our peers are peering at the pier on top of the pier. No wonder people get confused with English.
I always think about a jetty heading out at right angles to the shore and a wharf being parallel to the shore with a pier used for more gentlemanly pursuits like promanading or amusement arcades.
The use of the terms jetty, wharf and pier seem to be pretty interchangable with newspaper writers so searching all terms is recommended in resources like Trove.
