Aidrian, there certainly is that well known photograph of the CSS SHENANDOAH shown at the Williamtown dock, in Melbourne, which, if I remember correctly, can be seen at the Naval Historical Center's web site.
There is one other photograph of the vessel, supposedly taken in the harbor itself (Port Phillip Bay), which has been mentioned in a book on Australian photography, published in the 1950's, and which image I have been trying, for a couple of years, to locate, without much success, so far.
