The diagram above shows the Legislative Branch of the Australian Federation.
It includes the monarch as head of state, the Crown of Australia, the representatives of the head of state, and the parliaments.
It shows the one-to-many relationship between the monarch and his representatives, the Governor-General for the federal tier and the Governors for the states’ tier, respectively.
The next diagram shows the situation for Ireland. Ireland had a one-to-one relationship between the monarch and his representative, the Governor-General for the Irish Free State.
The model for the Republic of Ireland will not work for Australia. The proposals by the ARM for the 1999 referendum and the Australia Choice Model take their inspiration from the Irish model and will not work.
The next diagram shows how the structure of Australia’s Federation would change if the ARM Australia Choice Model is adopted through a referendum. With the ARM models, the monarch and Crown are abolished, and the Governor-General is promoted to head of state, similar to how Ireland transformed into a republic.
The ARM models leave many question marks and do not adequately think through the transition to a republic. The job is half done, with a half-baked republic being the result.
