A Newspoll of seven Queensland electorates shows Labor's primary vote is 38 per cent, down from 42.4 per cent since the 2010 election.
A sharp fall in Labor's primary vote across seven Queensland electorates since the 2010 election would result in the loss of four, possibly five, seats, a new poll shows.
The Australian newspaper reports there has been a swing against the government of almost five percentage points on a two-party preferred basis in Moreton, Petrie, Lilley, Capricornia, Blair, Rankin and Oxley.
The Newspoll shows Labor's primary vote is 38 per cent, down from 42.4 per cent in August 2010.
The coalition's primary vote in the seven Labor-held seats is 42 per cent, up from 39.8 per cent at the last election, meaning it would gain Moreton, Petrie, former treasurer Wayne Swan's seat of Lilley and Capricornia, if the swings are uniform.
Blair is also at risk.
Earlier polling that suggests Prime Minister Kevin Rudd could also lose his seat of Griffith means there is a strong possibility Labor will retain just two seats in Queensland - those of Rankin and Oxley.
The paper says Mr Rudd's home state is meant to offer Labor a springboard to claim coalition seats, but this now appears unlikely, particularly Brisbane, held by a margin of 1.2 per cent, and Forde, held by a 1.7 per cent margin.
Forde is being contested by former Queensland premier Peter Beattie.
Both Mr Rudd and Opposition Leader Tony Abbott have equal voter dissatisfaction in the seven seats of 49 per cent, however, Mr Abbott trails Mr Rudd as preferred prime minister 47 per cent to 40 per cent.
Across the seven seats, Mr Rudd's satisfaction rate was 42 per cent, while Mr Abbott's was 44 per cent.
The Newspoll was conducted from last Tuesday to Sunday.
