CANBERRA, Feb. 15 (Xinhua) -- The Reserve Bank of Australia (RBA) has revealed the design of Australia's new 50-dollar banknote.
The new banknote, which is worth 39.6 U.S. dollars, features portraits of Aboriginal author and inventor David Unaipon and Edith Cowan, the first female member of an Australian parliament.
The note, nicknamed the "pineapple" for its yellow color, has a string of security features including a top-to-bottom clear window containing dynamic features and micro-printed excerpts from Unaipon's book and Cowan's maiden parliamentary speech.
"Improved security and ease of recognition underpin the design of the new 50 dollar banknote," RBA Governor Philip Lowe said in a media release on Thursday.
"With the release of the five and 10 (dollar notes) during the past two years, we are confident the Australian public are becoming familiar with the new banknote security features.
"David Unaipon and Edith Cowan were campaigners for social change and we are proud to continue featuring them on the 50 dollar banknote. The new banknote provides the opportunity to tell more of the rich story behind these distinguished Australians."
Just as every other Australian banknote does, the new 50 dollar note also includes representations of a wattle and a native bird.
The 50 dollar note features Acacia humifusa, a type of shrub associated with Unaipon, and a Black Swan; the bird of Cowan's home state of Western Australia (WA).
The new five and 10 dollar notes, revealed in 2016 and 2017 respectively, encountered problems in their rollout with ATMs and other machines refusing to accept them.
However, the RBA said it was "working closely with banknote equipment manufacturers and retailers" to ensure a smooth introduction for the newest note.
The new 50 dollar note will enter circulation in October 2018 with the 20 dollar note set for a redesign in 2019.
