Referenda questions

The Australian Constitution can only be amended by referendum. For a referendum to succeed it must achieve a double majority:

  • an overall majority of votes in favour; and
  • a majority of voters in favour in a majority of States (ie. four States).

Australia has a poor record on Constitutional change. A total of 44 questions have been put since Federation. Only eight have achieved the required double majority (18.2%). A further five managed to achieve one majority but not the other. In considering this failure rate, it should be noted that a number of proposals have been rejected more than once.
