The bureau of statistics is set to release its first response rate estimate for same-sex marriage surveys – but preliminary polls suggest a positive result.
The tally will be released on Tuesday but will not include results of how the vote is split between 'yes' and 'no' camps.
In the meantime, polls are suggesting a strong turn out.
A Reachtel poll released on Monday and published by The Guardian predicts a victory for the “yes” vote, with 64.3% of respondents saying they had sent back their ballot and voted yes compared with 15.5% who had voted no.
Those numbers were echoed by SkyNews:
The bureau will provide weekly updates until the postal survey closes on November 7.
The results of the same sex marriage survey will be published on November 15.
