Melbourne: Australian Prime Minister Julia Gillard-led Labor Party's primary vote has dipped by three percentage points to 28 percent in the past two weeks, according to a latest survey.

According to the survey by Newspoll, published in a newspaper, Labor's primary vote which stood at 31 percent a fortnight ago was down by three points as compared to the Coalition primary vote, which has jumped from 43 percent in the same period to 47 percent.

This is the first time the poll has registered Labor's primary vote below 30 percent since October 2011, after reaching a low of 26 percent in September.

The poll also has the Coalition leading Labor on the two-party preferred 57-43.

Meanwhile, Gillard who is in Seoul to attend a major Nuclear Security Summit has brushed aside the survey.

On Saturday's election in Queensland, Labor Party was crushed to defeat, winning just 26.9 percent of the vote and losing 43 seats as the LNP swept to power.

"I could wake up every morning and worry about the polling or I could wake up every morning thinking about the future of the nation. I choose to do the latter," Gillard was quoted as saying in a report.

She pointed out that ALP needed to change its approach after its thumping loss in Queensland.

"This is a very difficult defeat for Labor, a very severe defeat for Labor, and that means that as a Labor Party in Queensland, and more generally, we need to listen," she said, adding, "But my job is to both listen and lead, and that's what I'll be doing as Prime Minister."

Gillard said she would continue to work on selling the Federal Government's policies.

"I understand that they are complicated policies and they are not the kind of thing that are instantaneously popular, but you become Prime Minister of the nation to make the decisions that are right for the nation's future," she said.

The federal Coalition enjoyed a four-point boost in its primary vote in the poll, and on a two-party preferred basis it holds a trouncing lead over Labor of 57 percent to 43 percent.

Opposition Leader Tony Abbott said the Prime Minister has a "real problem" with public trust.

"I think certainly sensible Labor people are asking themselves a lot of searching questions," he said, adding, "I think the Prime Minister is still in denial about the scale of the defeat in Queensland."
