On the sidelines of the APEC Summit in Peru, Mr Turnbull sought to tease out Mr Obama’s expectations of how US security and economic policy may change under the Trump administration.

Before the meeting, Mr Turnbull nominated trade and “our strategic commitments, particularly in the battle against terrorism” as key points of discussion.

Although Mr Obama’s term is ending, the Australian Government is keen to feed its perspectives on foreign policy into Washington DC, before the new administration takes power on January 20.

One official has described the meeting as a “stocktake” on current alliance activities.

Mr Turnbull has carefully avoided any criticism of Donald Trump since his election, but within the Government there is anxiety over how aggressive the President-elect may be in acting on his pledge to “take out ISIS.”

Before his meeting with President Obama, Mr Turnbull had a working breakfast in Lima with the Canadian Prime Minister, Justin Trudeau.

“Big political changes in your neighbourhood, I hear?” the prime minister quipped, before spending more than 40 minutes with the Canadian leader.

“We’ve had a very constructive meeting,” Mr Turnbull later reported.

“Canada and Australia have got a very common view of the world, of the security issues — we’re partners right across the board.”

Canadian officials briefed their travelling media that “migration” was canvassed in the meeting, but no further details have been provided.

The North American nation has been held out by both sides of Australian politics as a potential third country for refugee resettlement, the Australian Government has not said whether a deal was discussed by the prime ministers in Lima.
