The Finger Wharf was an operational working wharf for much of the 20th century. Each of the twin storey sheds was associated with a ship's berth and these berths were numbered 6 and 7 (on the east side), and 8 and 9 (on the west side). A extension to the wharf was added in 1916. Further development in the form of road building, wharf and pile repair, and shed construction continued up to early 1920s, expanding on the pattern already created. It then became one of the major wool dispatch points, the site of Sydney's only wool dumps (where wool bales are compressed by hydraulic plugs) and the terminal for some of the largest ships entering Sydney Harbour.
