Reserve Bank of Australia

The Reserve Bank of Australia confirms it issued approximately 46 million new Australian $50 notes in late 2018 with a typo in the background fine print: "responsibility" is misspelled as "responsibilty", the third "i" is missing. The mistake appears three times on the note and is extremely small requiring magnification to see. Part of the rollout of Australia's redesigned currency, the A$50 notes feature the first female member of an Australian parliament, social reformer Edith Cowan.
