Labor is heading for an election loss, with support for Kevin Rudd plummeting to new lows, the latest Newspoll shows.
The prime minister is in a worse position now than when he was dumped as Labor leader in 2010, while Opposition Leader Tony Abbott's popularity is climbing.
The Newspoll, conducted for The Australian on the weekend, shows Labor's primary vote is just 34 per cent, compared to the coalition's primary vote of 47 per cent.
Primary support for the Greens has dropped from 11 per cent to nine per cent.
On a two-party-preferred basis, Labor's support stands at 46 per cent - a drop of two percentage points - while the coalition's support has risen to 54 per cent.
Labor is now facing a four-point swing away from it since the last election, the Australian says.
Mr Rudd still edges Mr Abbott as preferred prime minister - 43 to 41 - but his support is dwindling, equating to a loss of three points from the previous poll and a rise in Mr Abbott's rating of four points, the closest Mr Abbott's ever been to Mr Rudd on the question of preferred prime minister.
Mr Rudd's voter satisfaction rating also dropped four points to 35 per cent, while his dissatisfaction rating rose six points, to 54 per cent, his worst ever personal support.
Mr Abbott's satisfaction rating, meanwhile, is on the up, with a rise of three percentage points to 41 per cent, up seven points during the election campaign, while his dissatisfaction rating was 51 per cent, down one point and a five point fall overall during the campaign.
The paper said it is the highest level of support Mr Abbott has received in more than two years.
