The national budget presented last week by Federal Treasurer Wayne Swan appears to have successfully boosted the poll numbers of the ruling Labor Party, according to the latest Newspoll survey.

The government has set aside some $5 billion assistance packages for financially challenged Australian families and days after Mr Swan unveiled the plan, Labor won back three points of its primary vote to end up at 30 per cent in the new survey, Newspoll said.

As Labor gained, the Coalition gave up six points and saw its primary edge over the government shrinking to 45 pe rcent, which remains a commanding 15-point margin more than a year before the general elections set in 2013.

The new Newspoll data also showed that in terms of a two-party face-off, voters have maintained their preference for the opposition headlined by Liberal leader Tony Abbott, by 10 points at 55 per cent as against to Labor's 45 per cent.

Prime Minister Julia Gillard, the survey said, still lags behind Mr Abbott in the preferred Australian leader department as 40 per cent of those asked have affirmed their support for the opposition leader, which also came with an approval rating of 34 per cent.

Ms Gillard managed to maintain her previous showing of 36 per cent as the country's favoured Prime Minister, with her satisfaction grade steady at 27 per cent.

The Treasurer has packaged the budget as a financial plan that would take care of how Australian households would live decently, especially who were earning less than $90,000 each year.

"This is a budget for the battlers. It's not about the polls, it's about relieving cost of living for families," Mr Swan declared last week prior to the unveiling of his budget blueprint, which generally scrambled to realise spending cuts of up to $40 billion.

But Labor's battle cry has yet to be absorbed by many Australians, Newspoll said, with only 18 per cent convinced that the spending adjustments set to be rolled out by the government would impact positively on their personal well-being.

About four out of 10 Aussies believe no personal gains will be spurred even if the budget is calibrated to gain surplus of $1.5 billion, the survey said.

Overall, the new budget will not make a huge difference to the domestic economy as the same number of respondents, 37 per cent on each end, balanced each other out in saying and opposing that business conditions will flourish even more as pledged by Mr Swan.

Trade Minister Craig Emerson has admitted that the Labor caucus should be vindicated by the 3-point climb suggested by Newspoll, which he said has somewhat proven that "if you continue to do the work and implement good policies for Australians, do the right thing and return the budget to surplus, then that will be acknowledged."

"I would imagine that (Labor MPs) would take some heart from the fact that (we) received a boost in the polls," Mr Emerson told Sky News on Tuesday.

However, Workplace Minister Bill Shorten said that while he appreciates the boost afforded by voters in the new survey, governance must not be swayed by opinion polls but by steady policies.

"I think it's smarter for the government to think long term and not just think in the Newspoll cycle," Mr Shorten told ABC today.
