So there was some sort of survey result yesterday?

 Some quick observations:

*  participation rate was higher than I expected.

* that means it was pretty accurate, and it did match polling quite closely.     Newspoll in September had this result:

The proportion of voters who support same-sex marriage now stands at 57 per cent, compared to 63 per cent in August and 62 per cent in September last year.
The no vote has lifted to 34 per cent, from 30 per cent in August and 32 per cent a year ago.
About nine per cent are uncommitted.

So, the Australian government spent $100 million to work out that Newspoll is pretty accurate.   Congratulations...

*  I wonder how the 20% who didn't vote would have gone if voting had been part of compulsory election voting.   Very hard to say - this article at The Conversation talks about that.

*  Further on that theme:  it's funny how non compulsory voting enables a different slant on things, isn't it?  The "best" that the conservatives/cynics on this issue (like me!) can argue is that of the total eligible voting population, it was actually only about a 49% yes vote and a 30% no vote.    Yet a 60/40 split in those who did vote enables people to call it an "over-whelming" yes vote.   (You see the same in government elections overseas, of course.)   Admittedly, you would have to say that compulsory voting would have sent the yes vote well over the 50%, but still, let's not get too carried away with the "overwhelming" adjective.   For me, for something like this, I would hold back "over-whelming" for something like a 65 plus vote.  

*  I think everyone is surprised by the strength of the No vote across a swathe of Western Sydney electorates.  What a divided city.   Fortunately, we live in a country where riots over social issues rarely happen.   So a bunch of Labor politicians are at some risk of annoying their electorates by voting Yes.   I suppose they can always say "look, doesn't make any practical difference if you were to say that all members should vote according to their electorate result, as if we did that, it would still mean only 17 No votes in the House.   Just live with it."  

*  Kind of amusing anyway how many, many National Party electorates went for "Yes", though.   Queensland was different in that regard, with two huge outback electorates going "No".    It does just confirm that Queenslanders can be very "different" in voting  patterns; but in most respects, not in a good way.  (I'm talking the ridiculous prospect of One Nation getting some power in Queensland parliament again in the next election.  High temperature just does something to the voting brain, I am sure.)
