There have been 44 referendums in Australia with eight proposed changes approved by a vote of the people. The eight successful constitutional referendums were:

The Australian Constitution can only be changed with the approval of the Australian people through a referendum. A proposed change must be approved by the Parliament and then be voted on by Australians in a referendum. A referendum is only passed if it is approved by a double majority, meaning it must be approved by a majority of voters in a majority of states, as well as a majority of voters overall.
