Yes campaign increases majority, new poll finds

A new poll released just hours before the same sex marriage postal vote results has revealed the Yes vote has remained ahead.

Nearly 80 per cent of eligible Australians took part in the voluntary poll and the outcome will be announced by the Australian Bureau of Statistics at 10am on Wednesday.

According to a Newspoll for The Australian, 63 per cent had voted Yes in the survey.

The poll, carried out among 1600 people, suggests a rise of one per cent from the last poll two weeks ago.

The Australian Statistician, David Kalisch, and his deputy Jonathan Palmer will make the announcement at a press conference.

The numbers will be broken down via state/territory and federal electorate, as well as by age and gender.

Prime Minister Malcolm Turnbull touched down in Canberra on Wednesday after five days in southeast Asia ahead of the vote.

The result is expected to mirror a myriad of opinion polls pointing to a win for the 'yes' campaign, possibly as high as 60 per cent.

If so, and all goes to plan in federal parliament, same-sex couples may be able to wed by Christmas.
