UPDATE: JULIA GILLARD says she isn't losing sleep over the latest poll showing Labor's primary vote stands at only 30 per cent.
The Prime Minister told Seven's Sunrise program that she sees a lot of opinion polls, and if she spent time worrying about them and commentating on opinion polls then she wouldn't have the time to get her job done.
According to a Herald/Nielsen poll published in Fairfax newspapers Federal Labor's primary vote stands at just 30 per cent.
It's a dip of five points since the last survey in December.
Support for the Coalition rose four points, taking its primary vote to 47 per cent - its highest level since just after the carbon tax began in July 2012.
On a two-party-preferred basis, Labor's support is at 45 per cent, well behind the 55 per cent for the Coalition.
Opposition leader Tony Abbott has also overtaken Ms Gillard in the preferred prime minister stakes, with his support leaping by 9 percentage points to 49 per cent compared with Ms Gillard on 45.
