I hope that a photo from a Melbourne passenger (or scanned from Sunraysia Daily) does surface.
The last instance of having two steamers in the lock simultaneously of which I am aware was in Sept.03: the return of the Randell Cadell fleet (PS Mary Ann, PS Lady Augusta and PS William Randell in convoy). I photographed the upriver locking in August, with two of these (or all three) in one locking.
PS Ruby was propelled up through the lock c2005 for a tourism expo, but at that stage its steam equipment wasn't fitted, and the propelling boat was PV Impulse.
