1977 Australian referendum
The 1977 Australian referendum was held on 21 May 1977. It contained four referendum questions and one non-binding plebiscite. To date, it is the most recent referendum to have been successful in Australia.
| Question | NSW | Vic | Qld | SA | WA | Tas | States in favour | Voters in favour | Result |
|---|---|---|---|---|---|---|---|---|---|
| (33) Simultaneous Elections | Yes | Yes | No | Yes | No | No | 3:3 | 62.2% | Not carried |
| (34) Senate Casual Vacancies | Yes | Yes | Yes | Yes | Yes | Yes | 6:0 | 73.3% | Carried |
| (35) Referendums | Yes | Yes | Yes | Yes | Yes | Yes | 6:0 | 77.7% | Carried |
| (36) Retirement of Judges | Yes | Yes | Yes | Yes | Yes | Yes | 6:0 | 80.1% | Carried |
This referendum had a particularly strong "Yes" vote. All but one of the referendum questions were carried, and the only one not carried had a clear national majority, but was held back by not achieving a majority of the states. No referendum since then has been successful.

The four referendum questions were only voted on in the states; voters in the territories only gained the right to vote on constitutional changes as a result of the Referendums amendment passing. Voters in the territories, however, were able to vote on the plebiscite.
