Just a handful of close advisers were privy to President Donald Trump's heated first phone call with Australian Prime Minister Malcolm Turnbull.

But despite just a few of Trump's inner circle hearing the tense conversation, details of the two leaders' supposedly blazing row have spread from Washington to Canberra - rocking the Turnbull administration.

The new President is said to have slammed Turnbull over a deal he agreed with Barack Obama which would have seen 1,250 refugees on Manus Island and Nauru shipped to the US.

A furious Trump is reported to have accused the Australian leader of trying to export the 'next Boston bombers' directly to the United States.

With no obvious whistleblower in the Oval Office during the telephone call on Sunday, some have suggested that one of Trump's own team may have leaked the conversation.

Sources in Canberra told the Sydney Morning Herald that Trump's chief strategist Steve Bannon may have briefed the Washington Post on the story.

While this seems unlikely at first thought, the insiders believe leaking the story may show Trump is against the refugee deal - even if it has to go ahead.

Under fire White House press secretary Sean Spicer and national security adviser Michael Flynn were also in the room as Trump and Turnbull supposedly engaged in a war of words.

Some believe Trump may have been angered when Turnbull brought up the deal during their first call since his inauguration, which the new President may have expected to be a mere exchange of pleasantries.

This may explain why he reportedly told the Australian prime minister that the conversation was 'the worst call by far' that day.

Trump had earlier spoken to Russian President Vladimir Putin, French President Francois Hollande, German Chancellor Angela Merkel and Japanese Prime Minister Shinzo Abe.

On Thursday afternoon the newly-elected president took to Twitter to slam the Obama administration for making the 'dumb deal' to take on 'thousands of illegal immigrants'

Sources claimed President Trump was 'yelling' at Mr Turnbull during the conversation

Trump was reportedly 'boasting' about his pleasant call with Putin when he told Turnbull the refugee agreement he struck with the Obama administration was the 'worst deal ever'.

Speaking about the 1,250 the US was supposed to be allowing into the country from Manus Island and Nauru, Trump is reported to have said: 'I don't want these people.'

He is also said to have complained that he was 'going to get killed' politically for following through on the resettlement agreement.

Sky News sources claim President Trump was 'yelling' at Mr Turnbull at points during the heated conversation.

Senior US officials told the Washington Post that Donald Trump abruptly hung up on Mr Turnbull after just 25 minutes - when the pair were meant to speak for an hour.

What is the Australia-US refugee deal? The Obama administration and Turnbull government struck a deal to resettle some of the refugees being held offshore in Nauru and Manus Island in November last year The Australian government has a 'zero tolerance' policy towards illegal boat arrivals and only genuine refugees are sent to Nauru and Manus Island There are approximately 1,250 refugees being held in the Australian-funded offshore detention centres A large majority of those refugees come from Iran, Iraq and Somalia - all countries on US President Donald Trump's travel-ban President Trump reportedly agreed to honour the deal, on the condition the refugees would undergo 'extreme vetting' The US President reportedly described it as the 'worst deal ever' in a heated conversation with Australian Prime Minister Malcolm Turnbull on Sunday Advertisement

After Mr Turnbull apparently suggested they move on and talk about foreign affairs, including the conflict in Syria, President Trump ended the conversation.

'During call with Australian PM on refugees, Trump pulled phone away from ear and says he wants off call, which ends abruptly per source,' CNN reporter Jim Acosta tweeted.

Trump later tweeted that the deal was 'dumb' and said he would be taking a second look at it.

The explosive report is a huge embarrassment for Turnbull, who has insisted in recent days the asylum seeker deal is solid and relations with Washington are fine.

'It's better that these things - these conversations are conducted candidly, frankly, privately. If you see reports of them, I'm not going to add to them,' the prime minister said.

Ross Cameron, a former minister for Turnbull's Liberal Party, said the leaked call could spell the end of his premiership, adding: 'He's finished.'
