Prime Minister Tony Abbott will visit the Arlington National Cemetery in Washington as his government considers creating a national war cemetery in Canberra to commemorate the Anzac centenary in 2015.
Mr Abbott will lay a wreath on Friday at the Tomb of the Unknown Soldier and view the changing of the guards at the final resting place of more than 400,000 active-duty service members, veterans and their families.
He raised the idea of creating a similar cemetery in Australia in 2013 at Legacy's national conference in Brisbane, describing it as "Australians' Arlington".
The concept would involve interring significant ex-soldiers.
The prime minister, who will host the G20 summit in November, will also on Friday discuss financial and economic issues with US Treasury Secretary Jacob Lew and Federal Reserve chairwoman Janet Yellen.

Mr Abbott will receive a military welcome when he visits the Pentagon for talks with Defence Secretary Chuck Hagel and the Chairman of the Joint Chiefs of Staff, General Martin Dempsey.
He will then head to Houston, where he will deliver a speech to the Asia Society.
Liquefied natural gas is also likely to be discussed during Mr Abbott's visit, with the biggest project occupying the minds of LNG industry figures being the Panama Canal expansion.
It will allow massive Post-Panamax ships to take American LNG to the booming markets of Asia to compete against the Australian product.
