Postal survey - did 'yes' really win?

The results are in. Over the last two months, around 12.7 million Australians expressed an opinion in the Marriage Law Postal Survey, answering the question ‘Should the law should be changed to allow same-sex couples to marry?’. With ‘yes’ receiving 61.6% and ‘no’ 38.4%, the answer may seem clear. Nonetheless, when it comes to Parliament actually legislating marriage reform, interpreting the meaning and relevance of these numbers has become the next contested space in public discourse.
In the following paragraphs, I’m not mounting a case for any particular legislative outcome. I simply want to make a fairly straightforward comment against one line of thought that I’ve noticed becoming somewhat popular in certain segments of social media.
I'm seeing more than a few 'no' supporters arguing that, because 20.5% of eligible voters chose not to participate in an optional survey, therefore the result is ambiguous, or at least somewhat indecisive. The argument goes that 61.6% of those who expressed an opinion said 'yes' and the participation rate was 79.5%, therefore ‘only’ 49% of eligible voters said 'yes' (0.616 x 0.795 = 0.48972).
Now I have all kinds of criticisms of this survey: its necessity, its function in public life, how it was conducted and so on. But anyone claiming the result was less than decisive ought to consider the figures from this survey in light of Australian (and global) electoral history.[1]
First comes the question of whether 79.5% is a high or low turnout for a non-compulsory survey. It is true that federal elections typically see a turnout of 90-95%, but they (a) are compulsory and (b) affect considerably more than a non-binding survey on a particular topic. Prior to voting becoming compulsory, not a single election saw a turnout as high as 79.5%. The highest was 78.3% (1917) and the lowest was 50.3% (1903). Although the recent question took the form of a postal survey, not a plebiscite, by way of comparison it is worth noting that the most recent plebiscite, held in 1977, saw 75% of eligible voters express a preference - and this was on a day where four compulsory referendums were also held. The two plebiscites held on conscription during WWI saw participation rates of 80.1% and 79.1% respectively. The non-compulsory postal ballot for the republican constitutional convention in 1998 had a participation rate of 46.9%. Participation in the survey was as high or higher than most national elections in comparable liberal democracies: for example, the 2017 UK general election (68.8%), 2017 Japanese general election (53.7%), 2017 New Zealand general election (79.8%), 2017 French presidential election (77.8%), 2017 German federal election (76.2%), 2016 US presidential election (between 55% and 60%, depending on methodology),[2] 2015 Canadian general election (68.3%), 2015 UK general election (66.4%) and 2014 US mid-term elections (36.4%). So to see almost 80% respond to a non-binding, non-compulsory survey is a very strong response rate.
But, more importantly, the argument that, because 'yes' fell (just) under 50% of total eligible voters, the result is invalid or inconclusive just doesn't stack up. If we applied the same logic to elections, we would end up with some strange outcomes.
Of the 49 Australian federal elections since federation,[3] only 7 have been won by a party (or coalition of parties) with more than 50% of the two-party preferred (TPP) vote from all eligible voters: 1929, 1931, 1943, 1958, 1966, 1975, 1977. The most recent instance was forty years ago. So, using the logic of disappointed 'no' supporters would mean declaring 42 of 49 federal elections inconclusive/invalid - despite compulsory voting! If we just look at primary votes, there is not a single election that has been won by a party gaining a majority of all eligible voters.
The largest ever victory margin in a federal election was in 1931 and the two-party preferred vote was 58.5% to 41.5%.
Thus, any federal election that won 61.6% to 38.4% on a two-party preferred basis would be the most comprehensive landslide victory since federation.
If we look only at primary votes, then the highest the Labor Party has ever received is 50.9% (1914), the highest the Liberal Party has ever received is 41.8% (1975) and the highest a non-Labor coalition has ever received is 54.3% (1919).
If the result of this survey were treated like a referendum, then it would pass, with the comfortable support of every state and with a strong overall majority.
If the results are calculated by electorate, as they are in a House of Representatives election, then 133 of 150 electorates (88.7%) opted for 'yes'. The most electorates ever won in a federal election was 71.6% in 1975.[4]
In absolute numbers, 'yes' received more support (~7.8m) than either Labor or the Coalition have ever managed at a federal election (the record is ~6.9m on two-party preferred and ~5.9m for primary votes).
Is this a ‘landslide’? Is it an ‘overwhelming’ win? Such terms do not have precise definitions, but both have frequently been used by both sides of politics and media commentators for electoral victories with smaller margins than the opinions just expressed on marriage reform. Whatever else you may think of the result, to claim that this survey was anything other than a very strong and decisive 'yes' to the legalisation of same-sex marriage appears either somewhat delusional or bad faith special pleading.

An interesting tangent/footnote: I note that in 1988 Australia voted on a referendum question offering to enshrine ‘freedom of religion’ in the Constitution. The motion was opposed by many churches and church schools and was roundly defeated 30.8% to 69.2%. Back in 1944, another referendum offering to put freedom of religion into the Constitution was defeated 45% to 54%. And a 1999 referendum that included adding a reference to God in a Preamble to the Constitution was defeated 39.3% to 60.7%. Again, I make no recommendations on the basis of this observation, other than recognising the shift that has occurred amongst many church leaders regarding the desirability of legal recognition of a right to religious freedom.

[2] Since the US does not have a federal electoral commission or its equivalent, getting reliable and consistent statistics on national voting data is not straightforward.
[3] Seven elections have been for the House of Representatives and the full Senate, thirty-two have involved the House and half the Senate, six elections were only for the House, and four were only for half the Senate.
[4] If all the seats in the intended coalition of the UAP and CP from the 1931 election are counted together, then they won 55 of 75 electorates (73.3%), but as the UAP won enough seats to govern in their own right this intended coalition never came to pass.
