The Spindoctors:I've just created a new category for Austraila Post Offices - based heavily on the Canadian Post Office category.
I presume this is the place to bring our request to Koko for an icon.
Ideally we're after smaller versions of the Australia Post logo - http://www.auspost.com.au/
The logo is typically reversed: red on white.
Koko typically seems to create the icons in bunches, probably much like we review... and it will get automatically assigned to your category when it is ready.
I'm sure that she researches the concept and creates something beautiful based on her understanding of the category and artistic flair... don't worry, you'll be proud to display the icon.
I like viewing mine as a personalized present..
