You might notice our early results are showing a huge majority of No votes – well in excess of anything predicted by the opinion polls.
That's due to a quirk of the counting and reporting process.
We're getting results from smaller centres in regional areas – where No votes are expected to comfortably outnumber Yes ballots – well before the larger, inner-city booths where the Yes vote will likely be stronger.
The Australian Electoral Commission will count every single ballot cast today, as well as a majority of the more than five million early votes cast over the last two weeks.
Postal votes, though, will take up to two weeks to be fully counted.
Unlike elections, the ballots themselves are expected to take far less time to count, as there's only two options to count and no preferences to take into consideration.
