I decided that her (whisper) vote was informal, but I was outvoted by my two PNG offsiders who allowed her to write my nickname (Diwai) on the ballot paper.
I was present at the count and my one vote was declared informal. I received no other votes or preferences.
Bring on the double dissolution. I will vote for myself and if I can convince my wife to vote for me and do a preference deal with the crazies I will be a big chance for the Senate.
PS: Then again maybe optional preferential is the sensible way to go.
