CANBERRA, Australia (AP) — Australia's central bank has taken responsibility for typos on 46 million bank notes after a radio station posted an image of the microscopic error on social media.

Triple M radio posted on Instagram on Thursday a magnified photograph of a 50 Australian dollar ($35) note showing the misspelling of "responsibility."

The word appears three times on the note and the third "i'' is omitted every time.

The Reserve Bank of Australia says the spelling error will be corrected at the next print run later this year.

Australia's high-tech polymer notes are among the most difficult in the world to counterfeit due to their extraordinary level of detail. The technology has been exported as state-of-the art to other countries.
