What model of republic will Australia have?

An Australian republic would replace the King or Queen of England and the Governor-General with an Australian as head of state.

The Prime Minister would remain head of the Government and the parliament would pass laws like today.

Australians should be able to decide whether our head of state should be elected by voters or elected by the Parliament.  The best way to make that decision is through a national vote, in 2020, before a full referendum in 2022.
