"Referendum (Machinery Provisions) Act 1984, Part III

Writing the capital letters WHY in the box complies with this requirement to ensure voters do not leave blank ballot papers for others to complete and that bribed or intimidated voters can easily disregard any unlawful instructions they are given without fear of retribution. It also frustrates any attempt to falsify the voters intention by altering a ballot paper to pretend that it could be a vote for YES or for NO.

Even if a majority in any State or the whole of Australia marks their ballot paper this way those ballot papers will not be counted as formal votes and the result will be determined by those who did vote either YES or NO.

It is highly unlikely that the overall result could be changed if enough people did switch from YES or NO to WHY. There just isn’t enough time or interest to mount a decent campaign.

But if YOU spread the word it might catch on enough so that the current clear majority for NO in every State instead becomes just a majority either way that could have been different if only their opponents had managed to come up with better arguments to persuade people who refused to vote in support of either side.

Then the people smugly convinced that they won because Australians are conservatives taken in by coalition fearmongering about the “dangers” might at least think there could be some other explanation.

Likewise the people smugly convinced that they lost because Australians are conservative and racist unlike the virtuous celebrities might at least become a bit less smug about it.

That could only happen if you also emphasize that the people you are spreading the word to should also spread the word to and convince the people they convince to also spread it.

Many of the people in each camp won’t think even if WHY got a majority.

But there are a lot of people disgusted with “both” sides and likely to not vote for either of them anyway. The more that do so, the more people are likely to start thinking.

Trees have roots, people have legs

Full disclosure: if I did have to vote, I would vote NO rather than appear to join in celebrating the Uluru “Statement from the heart”:

… the ancestral tie between the land, or ‘mother nature’, and the Aboriginal and Torres Strait Islander peoples who were born therefrom, remain attached thereto, and must one day return thither to be united with our ancestors. …
