Update: Antony has kindly clarified his reasoning in a comment on this article, and so I have now sent a follow up query to the AEC based on this.
Update 2: After much too-ing and fro-ing (see the comments) with Antony Green and the AEC it appears that the AEC would rather obfuscate on the whole issue than bring clarity to it, and Antony makes a very convincing case about why it is valid to do both. What I’d love to see is a comment from someone involved in the voting process with one of the OIC guides to confirm that it says that those votes are handled as Antony says. I somehow doubt anyone would dare though.. 🙁 After that enlightening discussion with Antony I’ve changed the title of this article from “Do Not Vote Both Above and Below the Line in the Senate! (Updated)” to “AEC Obfuscates on Voting Rules” as that seems to be fairer to both Antony and the AEC. 😉
Update 3: Just found this on the AEC website describing how voting works:
However, if the elector completes both sections formally, the below the line section takes precedence.
So it is really valid, despite what the AEC have been telling me! Thanks to “GetUp!” for providing the link to that AEC page on their voting page.
