SYDNEY, Oct. 29 (Xinhua) -- A redesigned 100-dollar banknote with new security and accessibility features entered general circulation on Thursday, the Reserve Bank of Australia (RBA) said in a statement.
The new banknote, which is worth 70.6 U.S. dollars, features portraits of World War I hero and civil engineer Sir John Monash and Dame Nellie Melba, Australia's first internationally renowned soprano.
A number of security elements have been incorporated in the new banknote to make it almost impossible to counterfeit, including a top-to-bottom clear window containing dynamic features, a patch with a rolling color effect and microprints featuring excerpts of a letter written by Monash and Melba's autobiography Melodies and Memories.
The note also features five raised bumps on each of its long edges to assist people who are blind or vision-impaired to identify it.
The 100-dollar banknote is the final denomination to be redesigned as part of the central's bank's Next Generation Banknote Program.
"The release of the new 100-dollar marks the completion of the decade-long program to upgrade the security of our banknotes," RBA Governor Philip Lowe said.
RBA Assistant Governor Lindsay Boulton said as the new banknote is gradually phasing in, the current 100-dollar banknotes can continue to be used.
'We anticipate it will take some time for people to regularly see the new 100-dollar banknote in circulation as our largest-denomination banknote is generally used as a store of wealth rather than for transactions," Boulton said.
"It is also important for people to know that the existing 100 (Australian dollars) banknotes can continue to be used and we expect both series of banknotes to co-circulate for some time."
The RBA has worked closely with banknote equipment manufacturers and retailers to help them prepare ATMs and other banknote authenticating machines to handle the new 100-dollar banknote.
