I don't think I need to remind you, folks, why it is a good idea to vote below the line for the Senate. Very simply put, it is TOTALLY UNLIKELY that the party that you want to vote for first will have preferenced the same way that you want to preference.
Theoretically, this should mean that Australians should vote below the line more often than not, but as we have discovered on numerous occasions, Australians couldn't give a rats arse about voting properly.
In my Senate post from the last election, I did a bit of a guide in how to vote below the line for Senate candidates. I have to update this now, because obviously it's out of date. And do bear in mind that this refers, primarily, to the Senate ballot paper for Victoria, but you could, potentially, use the same line of thinking for the other states as well.
