The latest gay marriage public opinion survey confirms earlier research that this issue is now on a near-inevitable path. There are large majorities of younger voters in favour: 74% of 16-24 year olds, 71% of 25-34 year olds, and 68% of 35-49 year olds. Only the 50+ age group are opposed, by a small plurality: 49% against to 45% in favour.
This opinon has arisen with surprisingly little debate compared to other countries, suggesting that is evolving out of general changed views on homosexuality rather than issue-specific campaigning. The downside of this is that there isn’t much pressure on the government to actually alter the law. Rudd’s personal conservatism is probably an obstacle to the law changing, and so it is not likely to occur without significant pressure.
