The Reserve Bank of Australia (RBA) has unveiled the design of a new $5 bill as part of a currency overhaul to improve banknote security.

The banknote will feature new security measures, including a new distinctive top-to-bottom window, the RBA said.

“Innovative new security features have been incorporated to help keep Australia’s banknotes secure from counterfeiting into the future,” said RBA Governor Glenn Stevens.

The new banknote will go into circulation from September 1.

In addition to its security features, the $5 notes will feature a new “tactile” element to help that will help vision-impaired people tell the different between notes.

The existing $5 note was originally issued in 1992, with a brighter version issued in 1995.

The portrait of Queen Elizabeth II shown on the front of the note was drawn from photographs commissioned by the RBA in 1984.

While keeping many original features, Australia’s new banknotes will each carry a different species of Australian wattle tree and a native bird, the RBA said.

The new $5 banknote depicts the Prickly Moses wattle and Eastern Spinebill bird. Future banknote updates will follow the same design principle, with each strip featuring a different species of Australian fauna and flora.

The current series of banknotes can still continue to be used after the new banknotes are issued.

Meanwhile, on Monday, New Zealand unveiled the designs of its NZ$20, NZ$50 and NZ$100 notes, which include increased security measures such as a holographic window, a colour-changing bird, puzzle number and raised ink.
