The figure above comes from a survey conducted on behalf of the Rationalist Association of NSW and the Humanist Society of Queensland. It can be spun in more than one way, of course, but it's still an interesting figure. Clearly, and overwhelming majority of Australians - including those with religious beliefs - are not voting along religious lines.
I'm planning to say a bit more about this over at Cogito.
Edit: Post at Cogito now made. I'll also republish it here when I have a minute.
