Scott Morrison has refused to criticise Donald Trump for undermining confidence in the US presidential election and insisted democracy would prevail.
The prime minister joined other world leaders in urging patience and trying not to be drawn into the fray.
"I have great confidence in the democracy of the United States and I have great confidence in their institutions," Mr Morrison told reporters on Thursday.
Joe Biden appears on track to become US president but Mr Trump continues to falsely claim the election is being stolen from him after prematurely claiming victory.
The Trump campaign has launched a series of legal challenges to fight results in closely-contested states.
Mr Morrison would not buy into suggestions of voter fraud in the United States, and said it was not yet appropriate for him to contact either candidate.
He said record turnout in the US election showed their democracy was working.
"We'll be patient and we'll await the outcome of their process. It's not for me to run a commentary on those things and I won't," he said.
"This is a democracy that has withstood the demands of centuries and I had have doubt it will continue to prevail."
Mr Biden has pulled ahead in crucial swing states but the president continues to peddle baseless claims of electoral fraud.
Opposition Leader Anthony Albanese said Mr Trump's demand to stop the count was the same as shouting "stop democracy".
"It doesn't matter whether you're the world's oldest democracy or the world's youngest, the people's right to be heard must be respected - and the democratic process must be allowed to run its course," Mr Albanese said.
"Australia should always speak out on the democratic values we hold dear."
Australia's former US ambassador Joe Hockey said Mr Trump would not take losing lightly.
Mr Hockey also alleged electoral fraud had definitely taken place, citing the 93 per cent result for the Democrats in Washington DC.
The Democrats have polled above 90 per cent in the US capital in every presidential election since 2008.
Foreign Minister Marise Payne remains confident of a clear election result.
"I'm confident that the US systems and processes that have stood the test of time will deliver an outcome and it is important that we wait for that," Senator Payne told the ABC.
"It's important that we respect that process, that every vote is counted, and I'm sure that they will be."
Senator Payne said there was no doubt the election stalemate was a "difficult moment" for the US.
Labor foreign affairs spokeswoman Penny Wong said Americans had voted in historic numbers and their votes should be respected.
"It's in Australia's interest that America remains a credible, stable democracy," she said.
