Prime Minister Scott Morrison has made US President Donald Trump's short and exclusive list of scheduled meetings on the sidelines of this week's G20 in Japan.
The White House announced Mr Trump's schedule in Osaka, with Mr Morrison slated for a meeting.
Chinese President Xi Jinping, Japanese Prime Minister Shinzo Abe, Russian President Vladimir Putin, Indian Prime Minister Narendra Modi, German Chancellor Angela Merkel, Saudi Crown Prince Mohammad Bin Salman and Turkish President Recep Erdogan also made Mr Trump's schedule.
Mr Trump is expected to land in Osaka on Thursday for the two-day Group of Twenty meeting.
Mr Morrison's meeting comes as the prime minister becomes more critical of the growing US-China trade war.
In a speech to be delivered on Wednesday in Sydney, Mr Morrison will warn Australia will not be a "passive bystander" if the US and China fail to find a trade solution.
"We should not just sit back and passively await our fate in the wake of a major power contest," the prime minister will tell the event.
A senior Trump administration official, during a G20 briefing in the US on Monday, told reporters the "president will focus a lot on trade" in Osaka.
The White House signalled it was in no hurry to solve the trade dispute with China and Mr Trump would use his meeting with President Xi "to see where the Chinese side is since the talks last left off".
"The goal here, as the president has said many, many times, and I'm sure he'll make clear again, is that the purpose of these discussions is to rebalance the economic relationship in a way that protects US economic prosperity and workers," the official said.
"And of course, that also means the kinds of structural changes that would need to take place to protect intellectual property."
Mr Trump will also use the G20 to engage with world leaders and obtain support as tensions rise between the US and Iran.
The official described the president's meeting with Mr Putin as "a normal event that happens at these" summits.
"It is expected to be a conversation that will focus primarily on regional security issues, including Iran, Ukraine, Syria, the Middle East," said the official, previewing the meeting with the Russian leader.
Mr Trump will depart Osaka on Saturday for South Korea where he will spend the night before departing for Washington DC late on Sunday afternoon.
