 The new $50 note was released for circulation on 18 October 2018, followed by the $20 note on 9 October 2019, and the $100 note is set to be released in the second half of 2020.The Reserve Bank currently has no plans to release fourth series banknotes in denominations higher than $100, despite the amount of inflation that has occurred since the $100 note was introduced in 1984.In May 2019 the Reserve Bank confirmed that the $50 note contains a misspelling of the word "responsibility" on the reverse design, a typo that would be corrected in future printings.
