Labor has stormed ahead in the latest national opinion poll, reclaiming its election-winning lead a week from polling day.

The Nielsen poll, published in today's Fairfax newspapers, shows Labor has gained four points to 53 per cent while the Coalition has slipped four points to 47 per cent in the two-party vote.

Labor's primary vote is up four points from 36 to 40 per cent, the Coalition down three to 41 per cent, while the Greens remain unchanged at 12 per cent.

The poll also shows the Greens preferences at a record high of 86 per cent in favour of Labor.

Prime Minister Julia Gillard has also charged ahead in the preferred prime minister stakes. She now holds a 14-point lead over Opposition Leader Tony Abbott.

But marginal seat polling in The Australian's Newspoll reveals that Queensland and New South Wales are swinging to the Coalition, but not enough for them to win government.

The poll shows swings of 3.4 per cent to the Coalition in Queensland and 1.3 per cent in New South Wales.

But there is a 6.2 per cent swing to Labor in Ms Gillard's home state of Victoria.

The surge in voter support for Labor follows a fortnight where the Opposition had the upper hand in the polls.

Last week's Nielsen poll showed the Coalition ahead 51 to 49 per cent on a two-party preferred basis.

Mr Abbott even emerged as the people's choice from the Rooty Hill RSL forum on Wednesday night, despite Ms Gillard announcing her biggest election promise yet that day - $2.1 billion for a western Sydney rail link.

In a Rooty Hill gaming chip exit poll, Mr Abbott picked up 71 votes compared to Ms Gillard's 59.

But Ms Gillard will start her day in Sydney today buoyed by the latest poll result.

Mr Abbott, meanwhile, will be heading to Perth with the hope of picking up some seats in Western Australia.
