Same-Sex Marriage - We've crunched and mapped the numbers

The Headline Numbers for the Territory

We've crunched and mapped the numbers for Australia's same-sex marriage postal survey. The nation as a whole voted 'YES' with 61.6% in favour of same-sex marriage equality. In the Northern Territory, 60.6% voted 'YES' but our participation in the survey was much lower, especially in the Electoral Division of Lingiari where almost half eligible voters did not participate.

Who Participated?

Rates of participation were the lowest in the country for young people (20-24 year olds) in Lingiari at 39.3%. It appears that nationally, 18 and 19 year olds took up the opportunity to participate as participation rates for this age group were generally higher than for their slightly older counterparts aged less than 30 years (see Figure 1 below). In general older Australians were far more likely to have participated in the survey.

The Nation in Maps

The results of the Australian Marriage Law Postal Survey are shown in the maps below. They illustrate the percentage of all fully completed (or ‘clear’ responses) with the yes box marked for each Commonwealth Electoral Division. The proportion of unclear responses was very minimal (0.2% nationally).

Areas coloured yellow in the map below show the 17 electoral divisions with under 50% responding yes. Areas shown in green and blue are where the majority of responses were yes, with the green representing more than 50% but less than the national average figure of 61.6%. Blue areas are where the percentages were above the national average, with the darker blue areas indicating electoral divisions where more than 70% of forms were yes.

The map below shows the highest ‘yes’ proportions were in and around Australia’s capital cities (see the two maps below for Sydney and Melbourne, for example). There are clusters of divisions which voted ‘no’ in Western Sydney (including Parramatta, Chiefly, Fowler, McMahon and Blaxland, which had the lowest ‘yes’ vote in the country at 26.1%). Interestingly, the division of Bennelong was a marginally ‘no’ at 49% ‘yes’. This is clear in the map for Sydney Divisions below. Another ‘no’ cluster was evident in north-western Queensland in the Divisions of Maranoa and bob Katter’s electorate of Kennedy. Another ‘no’ division in Queensland was Groom (currently a Coalition seat) in the south.

In Victoria, the only Divisions with a ‘no’ vote were Calwell and Bruce (both Labour held Divisions), however, overall Victoria was the strongest ‘yes’ State at 64.9%, however the ACT was higher at 74%.
