What is dollarydoo?

The dollarydoo was a satirical proposed currency for Australia, stemming from a 1996 episode of The Simpsons. In the episode "Bart vs. Australia", Bart makes a collect call to Australia, racking up a $900 bill. The Australian government demands recompense, leading to diplomatic tensions.

As part of the episode's humor, the Australian Prime Minister announces a plan to devalue the Australian dollar by introducing a new currency called the dollarydoo. This was purely for comedic effect and never intended to be a real economic policy. It serves as an example of the show's often absurd and exaggerated depiction of international relations.
