I put down no religion and explained to my sister that she should do the same. She can never even remember what type of church she was baptised in, so I pointed out that she obviously doesn't follow it enough to mark it as her religion.

Personally, I don't think it's helpful for people to put down 'Jedi Knight'. If you don't have a religion, then that's what you should put down. Otherwise, the government will just ignore those forms and continue supporting "Christian values" because they think that the majority of Australians are Christians. Personally, I'd love to see the Australian Christian Lobby get less support from the government.

As for those who didn't put down a religion... perhaps they didn't know what they identified as? Like maybe they are agnostic, so they didn't want to put down 'no religion', but couldn't think of what to actually call their beliefs?
