Australia has periodically experienced movements seeking to end the monarchy. In a 1999 referendum, the Australian people voted on a proposal to change the Constitution. The proposal would have removed references to the Queen from the Constitution and replaced the Governor-General with a President nominated by the Prime Minister, but subject to the approval of a two-thirds majority of both Houses of the Parliament. The proposal was defeated. The Australian Republican Movement continues to campaign for an end to the monarchy in Australia, opposed by Australians for Constitutional Monarchy and Australian Monarchist League.
