Dear Australian wikimedians

I am hoping that you might pick out the photos which for you were the most valuable in terms of their contribution to wikimedia (that is, wiki commons, wikipedia(s), and wikidata.

It may be that they motivated you to write an article, or to insert them in an article. Or that they meant you needed to add many more items to wikidata, or add new categories to commons (which meant of course, that you had to go hunting for already uploaded items which satisfied that new category).

(I have chosen four photographs, but I'll let you know which they were and why, after you have had a think about this...)
