The Constitution Alteration (Democratic Elections) Bill 1974 was an unsuccessful proposal to alter the Australian Constitution to make population instead of electors, the basis of determining the average size of electorates in each state. It applied not only to the House of Representatives, but also to the various state Legislative Assemblies, requiring the use demographical population size to ensure democratic elections. This was intended to replace alternative methods of distributing seats, such as geographical size, with instead the population of states and territories. It was put to voters for approval in a referendum held on 18 May 1974.

Background

The referendum was held in conjunction to the 1974 Federal Election on 18 May 1974. After the rejection of 6 Bills by the Opposition-controlled Senate, a double dissolution election was called from the 1974 Federal Election. The incumbent Labor Party led by Prime Minister Gough Whitlam defeated the opposition Liberal-Country coalition led by Billy Snedden. While this was the case, the Liberal-Country Party Opposition retained control of the Senate.

The view that political information is limited during referendum processes has been supported by various political scholars.
