I think this can be objectively answered, hopefully.
Apparently the most photographed building in the southern hemisphere is the Sydney Opera House. Makes sense, pretty popular, scenic location etc.
However, numerous results on google point to the Dunedin Train Station as being the second most photographed.
I was there years ago, and again this week. It's...a nice building, but it's nothing spectacular. Is there a reason I'm missing as to why it's second? Or is this just a story made up to try and make it more popular?
