Prime Minister Julia Gillard will reportedly spend a week living in western Sydney in a bid to halt the plummet of Labor's vote in the area.

Ms Gillard will spend next week on a mini-campaign in the outer suburban region, including sleeping in a Rooty Hill hotel, Fairfax reports on Tuesday.

The move comes as the latest Newspoll shows voter satisfaction with the prime minister has dived to its lowest since August last year.

Opposition Leader Tony Abbott has a clear lead as preferred prime minister for the first time since July last year.

Labor's primary vote also languishes at a seven-month low, at 31 per cent compared to the coalition's 47 per cent, according to the poll published in The Australian on Tuesday.

Many of Labor's western Sydney seats are marginals that would be lost if these results were replicated at an election.

In January Mr Abbott kicked off his own mini-campaign with a rally in western Sydney.

However his campaign was interrupted when Ms Gillard announced the real election campaign would start on August 12 with the polling day on September 14.

Ms Gillard's office has been asked for comment on her mini-campaign plan.
