The next generation of $20 banknotes have entered general circulation this week. 
The $20 is the fourth denomination in the new series of banknotes that have been released as part of an upgrade to banknote security. It follows the release of the $5, $10 and $50 banknotes over the past three years. The new $100 banknote is expected to be released in 2020.
Governor Phillip Lowe describes the new $20 banknote as “fantastic”. He says it features “world-leading” security technology and iconic imagery.
“Among my favourite features are the top-to-bottom window and the kookaburra, whose wings move up and down as you tilt the banknote,” he said. 
“It also provides a great opportunity to tell stories about people and organisations who have contributed to our past and present. One side of the banknote is dedicated to a convict turned astute businessperson, Mary Reibey, and the other to Reverend John Flynn and the wonderful Royal Flying Doctor Service.”
‘Tactile’ feature
The new banknotes have a ‘tactile’ feature to help people who are blind or who have low vision. This will help them distinguish between different denominations of banknotes. On the $20 banknote, this is three raised bumps on each of the long edges of the banknote.
Existing $20 banknotes
The existing $20 banknotes can continue to be used as all previously issued banknotes retain their legal tender status.
The existing series of banknotes will be withdrawn from circulation over time.
