The second-last postal survey estimate before the November 7 deadline puts the return figure at 12.3 million, or 77 per cent of all eligible Australians.
The Australian Bureau of Statistics released the figures today, indicating an increase of 400,000 since last week.
“There’s still time to have your voice heard even if you haven’t posted your ballot yet. The deadline isn’t until the 7th of November, so posting your ballot this week means it still can get there.
“It’s not too late. Don’t throw it in the bin, put it in the post,” Brady said.
“Don’t expect marriage equality to get over the line with someone else’s vote. If you want marriage equality to happen you have to make your voice heard.”
If you haven’t returned your form it’s not too late, as they can be returned in person at drop-off centres in capital cities listed here.
Forms can be returned to drop-off centres between 8:30am and 4:30pm on weekdays up to November 7 (excluding Melbourne, where November 6 will be the final day due to the public holiday).
The ABS has also advised that Australians using online response forms and the Interactive Voice Response have until 9pm (AEDT) on November 7 to register their vote.
The final result of the postal survey will be announced on November 15.
On Sunday, Liberal Senator Simon Birmingham said marriage equality could become a reality before the end of the year should predictions of a successful Yes response hold true.
“We see that there is no reason that it cannot be delivered before Christmas,” Birmingham said.
