Labor has slammed Prime Minister Tony Abbott, declaring him embarrassing for cancelling meetings with the world's top finance officials during his visit to the United States.
Deputy opposition leader Tanya Plibersek said Mr Abbott had made a succession of missteps during his travels overseas, the latest in the US.
"Australians have to worry that he'll be embarrassing us on the world stage," she told reporters in Sydney.
That follows a report from political columnist Laurie Oakes who said Mr Abbott had cancelled long-planned meetings with US treasury secretary Jack Lew, International Monetary Fund head Christine Lagarde and World Bank president Jim Yong Kim.
Ms Plibersek said that followed the embarrassing spectacle of Mr Abbott talking about Australian political issues "washing Australia's dirty laundry" at the Davos conference.
Six months down the track, the relationship with Indonesia still wasn't back to normal, she said.
Ms Plibersek said it was extraordinary that Mr Abbott wasn't meeting the top economic officials at a time when Australia was preparing to host world leaders for the November G20 summit.
"The G20 is the most important international meeting that has ever been held on Australian soil," she said.
Ms Plibersek said the rest of the world was moving forward on climate change action but Mr Abbott was a "Nigel no-friends" on the world stage.
