While nearby Grovedale to the west has expanded Marshall still contains light industry and many open spaces alongside a growing but small residential population. The Barwon Heads Road runs by the suburb and the Barwon River borders many historic sites - not least among them are the remains of the 1915 sewage aqueduct. The urban centre is near the intersection of Marshalltown and Barwon Heads roads with a reserve tennis court and a large retirement village.
