They messed up.

The processes involved are pretty foolproof. If on election night during counting it is noticed that one ballot paper is missing AEC staff will search the bins. Every cock and balls must be accounted for.

Yes so did someone get lazy and not bother to follow procedure

From reading that news item, it looks like people did the training but didn’t turn up on election day to work and they were scrambling for staff. Possibly some people got roped in who weren’t properly versed in the procedures.
