| 15 Nov 2010 | 14 Mar 2011 | 4 Jul 11 | Vote Labor | Vote Lib/Nat | Vote Greens | |
| Should be allowed to marry | 53% | 49% | 54% | 65% | 41% | 85% |
| Should not be allowed to marry | 36% | 40% | 35% | 23% | 48% | 9% |
| Don’t know | 11% | 10% | 11% | 12% | 10% | 6% |
54% think that people of the same sex should be allowed to marry and 35% think they should not. This represents an increase in support for same-sex marriage since this question was asked in March – however, similar to the result from last November.
Strongest support came from women (62%) and those aged under 35 (63%).
