North Arm
Just before the bridge out to Garden Island and Torrens Island, where the North Arm meets there Port River, there is a jetty and an adjacent floating wharf which I think is a market on some days. The wharf was fenced off when we visited. It was not so substantial as to warrant another visit. West of the wharf is the jetty. It's fairly short with an arm to the right at the end. Fortunately, it wasn't locked when we visited. On the outside of the jetty is a wave barrier of wooden slats. It's a working jetty and had a number of moored fishing boats. They clearly have booms that swing out but I'm not sure what sort of fish they catch.
