Here is a fake $50 I intercepted and photographed before handing it in. On a busy day, presented at the right time, I can see how this would have made it’s way into the day’s takings. Two simple checks would have avoided accepting it: the clear window did not feel integrated with the note and the material was more paper than plastic in the feel.
The Reserve Bank of Australia has excellent information on detecting counterfeits for each Australian note. I’d suggest we all ensure all our staff review this and thereby are more informed at detecting fake notes. We appear to be in a period of high circulation of fakes at the moment.
