Treasurer Wayne Swan said on Sunday that global uncertainties remain a serious concern for Australia's economic policy managers but insisted that the robust domestic economy serves as a firm firewall against the challenges ahead.

This environment, he later added, will underpin the programs, set to unfold over the next decade, that were outline by the federal government.

In his weekly economic note, Mr Swan pointed to the national accounts released last week, which showed that Australian fundamentals were hard at work, evident, he added, on fresh economic data that highlighted "solid growth, low unemployment, healthy consumption, contained inflation and lower interest rates."

What were seen, the Treasurer said, should serve as a clear reminder "that even in the face of many challenges we should never lose sight of our strong fundamentals."

In a report by the Australian Associated Press (AAP), Mr Swan lauded "the resilience of our workers and businesses, and our proven track record of dealing with global instability."

He assured too that Australia's solid economic path will remain that way as it is supported by an investment pipeline of about $500 billion, more than half of which, he added, were now underway.

Addressing the Parliament on Monday, the acting prime minister noted too that even former Prime Minister John Howard has conceded in an August speech that the Australian economy is currently the best performing among the key global markets.

Mr Swan said he is confident that all government programs, unleashed earlier by Prime Minister Julia Gillard, will be duly funded despite fears expressed by the Coalition that federal authorities will greatly struggle to finance the various commitments they have pledged to deliver.

According to Opposition Leader Tony Abbott, Mr Swan is pressured to come up with $15 billion budget each year in order to keep Ms Gillard's promise funding for the national disability insurance, the school reform funding and the dental care.

With the federal tax revenues retreating since 2008, it is likely that the Gillard Government will plug its budget holes by implementing new taxes, apart from the controversial mining and carbon taxes that took effect July this year, Mr Abbott said.

What the government has vowed to implement will take place, Mr Swan insisted, hinting too that even if new taxes would be introduced by Labor, they will never exceed the levels that were seen during the Liberal Howard Government.

"We in government have made the commitment to keep tax below the level that we inherited - 23.7 per cent of GDP (gross domestic product)," The Australian reported the Treasurer as saying on Monday.

Mr Swan, however, sidestepped Coalition demands that the federal government should discount the possibility of imposing high taxes.
