Australia released it's first polymer note as a commemorative back in 1988. It had plenty of issues then and the 5 dollar note was released in 1992. The 10 dollar note was released in 1993.
However there seemed to be quite a fair bit of issues:




As you can see, the intensity of blue is perhaps way too dark as well as there wasn't enough time given to let the ink dry. As a result, you can see the impression of the digit "10" and "Ten dollars" in reverse on the obverse. Pretty neat really.
In the following year, a quick fixup was done and this is how most notes look like these days:


Now these notes can be quite difficult to find in circulation.
