Plebiscite
In Australia, a plebiscite (also known as an advisory referendum) is used to decide a national question that does not affect the Constitution. It can be used to test whether the government has sufficient support from the people to go ahead with a proposed action. Unlike a referendum, the decision reached in a plebiscite does not have any legal force.
Australia has held two national plebiscites, in 1916 and 1917, relating to the introduction of conscription during the First World War; both were defeated. No specific rules exist about the running of a plebiscite. In the event that another plebiscite was conducted, it may be that the Parliament will decide on the rules of operation.
