Does anyone know just how the hell this actually works?
It was explained on the ABC morning show today, yes, I am at home this week and have no life...
For a postal vote:
You fill in your paper and seal it in an envelope. You then stick that envelope in another envelope, on which you fill in all the boxes so they can find you on the electoral role and sign it to say it was yours. It then all gets sealed in another envelope and that all gets posted.
It arrives at the tally room for your electorate (all have to go to the electorate you are voting in are to be counted).
The outer envelope is opened and discarded.
The middle envelope details are compared against your entry in the role to make sure it is you and that you didn't vote twice.
That envelope is opened and retained as evidence that you voted just in case the result is disputed in court.
The unidentified inner envelope is removed and placed in a container until such time that there is a sufficient sized batch assembled to make counting worthwhile. Then the unidentified inner envelope is opened and the votes counted.
So the chance of them tracing back that it was you that drew a big penis on the senate ballot paper are low.
