US President Donald Trump would be welcomed by both Liberal and Labor if he decides to visit Australia during a tour around the APEC meeting in Papua New Guinea in November.
Mr Trump, along with other world leaders, is expected to make stops in Australia as part of a tour that will take him to the Asia-Pacific Economic Co-operation leaders' summit in Papua New Guinea on November 17 and 18.
One option being considered is Mr Trump visiting Sydney, Canberra and Cairns, but nothing had been "locked in" yet, a US government source told The Australian newspaper.
Federal cabinet minister Christopher Pyne said any president of the United States is welcome in Australia, despite a high chance of protests.
"We have 100 years of mateship with the United States this year, of course we would welcome him here," Mr Pyne told reporters in Adelaide on Saturday.
"There's almost always protests when an American president visits Australia."
Labor deputy leader Tanya Plibersek said Australia's relationship with the US was very valued and important for national security.
"That doesn't mean that we should be unquestioning allies," she told reporters in Sydney.
"We will always make foreign policy decisions based on our own national interests."
Mr Trump could also fly into Brisbane, an expected entry point for leaders on their way to PNG.
It would be Mr Trump's first Australian visit as president.
