Like B233a, but new date (2020) and new signatures (Lowe/Gaetjens).
B233a contains a typo in the microprinting. Specifically, the back of the note contains Edith Cowan’s first speech to parliament in microtext above her shoulder, in which the word “responsibility” is repeatedly misspelled as “responsibilty” without the third “i” at the end of the word. The Reserve Bank of Australia corrected the error on subsequent issues.
