A record 30 per cent of women have yet to decide whether they prefer Malcolm Turnbull or Bill Shorten, an analysis of recent Newspolls shows.
The analysis taken for The Australian over the past two months shows the Labor leader has attracted a surge in support from men.
The poll of 6819 voters over that period shows support for the coalition among men and women is at 41 per cent, compared with 36 per cent for Labor.

But the government's primary vote has tumbled 7.4 points among men since the last election, more than double the 2.9-point drop among women.
Although almost all the men switched their support to Labor, the coalition's lost female vote has been split evenly among Labor, the Greens and other parties.
Among men, Mr Turnbull leads as the preferred prime minister over Mr Shorten by 50 per cent to 32 per cent but the Labor leader has picked up a significant 10 points since April while Mr Turnbull has shed eight points.
Women back Mr Turnbull as the better PM by 45 per cent to Mr Shorten's 25 per cent, but have marked the Liberal leader down seven points in the past two months.
A record 30 per cent of women are undecided.
