Australia and the United States must work together now more than ever before, Treasurer Josh Frydenberg has declared.
His intervention comes as the federal opposition tries to put the spotlight on divisions within the coalition government over a rising China, and its trade war with the US.
Mr Frydenberg told an American-Australian Leadership Dialogue event Canberra has a duty to stand with Washington in times of global uncertainty.
"It's not only our privilege to be strong, it's our duty to be strong and this is where America's place in the world is so important," he said in Perth.
"It's more important than ever that our two great nations, the United States and Australia, work more closely than ever.
"We need to work together in an unprecedented way across the economic, the strategic and the political realms, and to do so consistent with our values, consistent with our objectives, and faithful to our history."
Liberal backbencher Andrew Hastie was criticised last week for likening the global response to China's rise to Europe's lack of preparedness for the growth of Nazi Germany.
Mr Hastie, who chairs federal parliament's intelligence and security committee, drew a mixed reaction from his coalition colleagues and condemnation from Beijing.
Michael Shoebridge from the Australian Strategic Policy Institute said the Liberal MP made some salient points about the way China uses its power in the world.
He described the response to Mr Hastie's comments as hysterical.
"We need to be much calmer about this," Mr Shoebridge told Sky News on Monday.
"The public are primed to have a sensible discussion, and that's what we need from our political leaders, too."
Speaking at an Indo-Pacific Defence Conference in Perth, Defence Minister Linda Reynolds said nations in the region were growing increasingly concerned about growing tensions between the US and China.
"The US-China bilateral relationship is the most globally significant and it is in no country's interest to see competition become adversarial," Senator Reynolds said on Monday.
Cracks within the coalition have appeared between senior ministers with stewardship over the economy, as opposed to those with national security front of mind.
"I think where we've landed at the present period of time is a sense of confusion about what is one of the most important issues that Australians will have to grapple with for the next 25 to 50 years," Labor's Anthony Byrne told ABC radio.
"It would be good to have a cohesive conversation about this, a measured conversation about this, a calm conversation about this."
Prime Minister Scott Morrison said his government was fully aware of the complexities involved in Australia's security and trading relationships.
"We are careful as a government to ensure we do not make them any more complex than they need to be," he told reporters in Sydney.
