If we agree to this, there's another amendment that it would be an offence if you were to break your confidentiality on this. Obviously, this one goes with the one that we'd vote on later.
Also, citing the previous things, if we rely only on the secrecy of the vote, where is the point at which someone is relieved of that duty of secrecy? Reading the other points you cited, conceivably it would follow that that person is now almost bound for life, whereas here it's clearly stated that once the voting is closed, then you can be relieved of that responsibility of secrecy.
Based on what was cited earlier, there is no provision for that relief of secrecy, which is obviously not the intent. Going back, you can call this redundant if you like, but a certain level of specificity is needed. When you're counting votes an hour before polls close in an electoral district, having it clearly stated that thou shalt not be releasing these numbers before polls close is important.
Then, of course, our further amendment 140-something, to make it an offence, I think is a worthwhile endeavour.
