Reserve Bank of Australia (RBA) - you had ONE job.
After rolling out a total of 46 million new $50 bank notes in October 2018, one eagle-eyed Australian has noticed the note has a typo.
The reverse text on the note features excerpts from Edith Cowan's maiden speech to Western Australian Parliament.
When looking under a magnifying glass, one of the phrases from Cowan's speech - which is repeated three times - has misspelt the word "responsibility" as "responsibilty"; without the third 'i'.
An RBA spokesman said, "The Reserve Bank of Australia is aware of it and the spelling will be corrected at the next print run."
The full excerpt from Cowan's speech reads: "I stand here today in the unique position of being the first woman in an Australian parliament. It is a great responsibility to be the only woman here and I want to emphasise the necessity which exists for other women being here. If men and women can work for the state side by side and represent all different sections of the community, I cannot doubt that we should do very much better work in the community than was ever done before."
The new $50 is similar to the old note with portraits of Aboriginal author David Unaipon and Cowan, the first female member of the Australian parliament.
It features new security features and tactile elements to aid the vision-impaired.
"This latest and important upgrade not only marks a hugely significant step towards equal access to society for people who are blind or have low vision but also incorporates new, innovative security features that further protect against counterfeiting," Treasurer Josh Frydenberg said at the time.
"The application of the tactile features to the $50 note is particularly important given that it's the most widely circulated banknote, with 46 per cent of all banknotes in circulation being the $50 note."
He added, "I believe, the implementation of the tactile features would have made David Unaipon and Edith Cowan proud."
