Constitutional conventions in Australia are significant meetings that have debated the Australian Constitution. The first two gatherings debated Federation and what form of Constitution to adopt, while the following conventions debated amendments to the document.
The draft Constitution that was the final product of the first two conventions was approved at referendum in 1899 and 1900 by a 72% "Yes" vote on a 58% turnout.[1] There have been four of the latter conventions post Federation, but no constitutional proposal from these has been approved by referendum, and those put to referendum (proposals from the 1942 and 1998 conventions) were soundly defeated, reaching no more than 46% approval[2] on 90% to 96% turnout.[3]
