The poll published in The Australian today has the Coalition at 46 and Labor 54 per cent on a two-party preferred basis, while primary support for the government dropped from 37 to 36 per cent.

Labor’s support remained steady at 38 per cent while both One Nation and the Greens remained steady at 8 and 9 per cent respectively.

Turnbull also lost ground to Bill Shorten as preferred prime minister, his 42 per cent to Shorten’s 31 a four-point fall since the last poll.

Newspoll has also found softening support for same-sex marriage.

The proportion of voters who support same-sex marriage now stands at 57 per cent, compared to 63 per cent in August and 62 per cent in September last year.

The no vote has lifted to 34 per cent, from 30 per cent in August and 32 per cent a year ago.

About nine per cent are uncommitted.

Newspoll collated its results from a survey of 1695 voters polled across the nation over four days from Thursday.

Support for same-sex marriage was highest among Labor and Greens voters, at 70 per cent and 85 per cent respectively.

But conservative voters are trailing, with Coalition backers polling 47 per cent, alongside 35 per cent for One Nation supporters.
