Almost 60 per cent of eligible Australians have cast their votes in the same-sex marriage postal survey, but campaigners from both sides of the debate insist the fight is far from over.
The Australian Bureau of Statistics received about 9.2 million ballots by the end of last week, accounting for 57.5 per cent of the forms it sent out.
"We hope that this update will serve as a reminder to those who have not submitted their form to do so promptly if they wish to have their say," deputy statistician Jonathan Palmer said on Tuesday.
The ABS, which published the estimate on Tuesday afternoon, will provide an update every week until the postal survey closes on November 7.
The count is based on Australia Post's assessment of the number of containers of sorted envelopes rather than a count of individual forms.
