In January 2020, the Australian Republic Movement announced its intention to adopt a formal position on a preferred model for an Australian Head of State. This work proceeded on the premise that the primary barrier to Australia becoming a republic is not the British Monarchy, but uncertainty. Australians want to know what the credible alternative model is.

The Australian Choice Model was developed through extensive consultation and research. It describes what changes need to be made to Australia's Constitution so that the public can vote for the Head of State.
