Australia’s currency is one of the most advanced in the world.
Australian dollar notes are made of a polymer, which has a waxy feel, while the banknotes of the U.S. and several other countries are made of cotton fiber paper.
Polymer banknotes tend to last two to three times longer than paper notes. The feature could reduce replacement costs — for reference, the U.S. $10 bill is replaced every four and a half years.
Australia is continuously innovating with its banknotes, too. Its new A$5 banknote boasts a rolling color effect and, when moved a certain way, you’ll even see the image of an eastern spinebill (a native bird) moving its wings and changing colors.
