How dense do the store owners have to be?!!!

"Invasion currency"
The Chinese writing was on the back of the notes. The old style notes.
Shopkeepers, mostly in sleepy Tasmania, not expecting forged bank notes from "the lovely people of Tasmania" would likely have taken the notes, and while talking in a friendly manner with their customers just put the notes in the drawer and given change.
McDonalds in NSW has signs in all their stores stating they have forged bank note detectors in operation.
