Voting on 27 May 1967

There were two issues for consideration at the 1967 referendum.   

The first was a proposal that the number of members of the House of Representatives could be increased without a corresponding increase in the number of senators. This was supported by the Liberal Government and the Labor Opposition but not by other political parties including the Democratic Labor Party and Liberal Reform. Despite their differences all these groups were united in their support of the proposal to change the two sections of the constitution relating to Aboriginal Australians. 

In the referendum less than 40% of voters approved the change involving the number of parliamentarians but more than 90% approved the changes to the sections relating to Aboriginal Australians.
