The new $5 banknote has a range of security features that have not previously been used on an Australian banknote and that will help to keep our banknotes secure against counterfeiting into the future. New features include a world-first clear top-to-bottom window and a number of dynamic features that change as the banknote is tilted. The $5 banknote is the first in a new series and other denominations will be upgraded over coming years. The new series also includes a ‘tactile’ feature to help the vision-impaired community distinguish between different banknote denominations. The tactile feature on the $5 banknote is one raised bump on each of the long edges of the banknote next to the top-to-bottom window.
