Colin......she must have been a member of the British Pacific fleet as I see her below.....just east of the Sydney harbour bridge & also @ the wharves just across from Garden Island Dockyard ....[my old place of work].....
....
Looking further...she could also be in the Captain Cook graving dock @ GID?............the buildings to the right look familiar....for 40 years ago?........
Also the very first image is HMS Glory departing with Sydneys North Head on the port quarter....
