The School of Arts at Bondi was erected c1914 .... which puts it into the "right" era for the dating of the photos
(Google maps 138 Bondi Road, BONDI .... and nearby was a Masonic building which would have needed to be built LATER than the School of Arts as IF this is the "right" address, then the land for the Masonic building was vacant when the photo was taken)....
And the School of Arts building has lost the WING and verandah from the far left (looking at the photo) of the building...
Has Bondi Road been widened .... since the photo, or perhaps/likely we have not yet found the location for the photo .... Barry had suggested London or Melbourne or near the port ...
I tend to think the sky is too bright to be UK, but that could well be because I am so used to NSW sunlight and the photo may not be protraying the light accurately... There's possibly a much better photographic explanation as to the "bright sky" I notice in the black and white photo, but I am not ever to be thought of as a anything but an amateur in the fields associated with photographs...
