Politically, republicanism is officially supported by the Labor Party and the Greens, and is also supported by some Liberal Party members of the Australian parliament. Australian voters rejected a proposal to establish a republic with a parliamentary appointed head of state in a referendum held in 1999. This may have been mainly due to the fact that many on the “Yes” side voted “No” at the referendum in rejection of the proposed system of a parliamentary appointed head of state rather than being elected by the people. This was despite polls showing a majority of Australians supported the republic at the time.
