Stefanovic grilled Mr Turnbull on Thursday morning over Parliament's worsening citizenship fiasco, asking the Prime Minister whether he and his government would survive it.

Dismissing the "frenzy", Mr Turnbull proceeded to lay out the government's work in response to North Korea, terrorism in South-East Asia, meetings with world leaders, company tax cuts and job creation.

Interrupting the one-minute answer, Stefanovic said: "PM, with the greatest respect, you are waffling this morning."

Taken aback, the Prime Minister hit back: "Well, Karl, you've got a job. If you are looking for a job and you need a job and you've got one because of the strong economic leadership we've provided, you may think it's 'waffling'. But if you've been unemployed and you're getting a chance to get ahead, you would say you are being very patronising - saying young people getting jobs is 'waffling'."

Stefanovic replied: "OK, this is what I want, this is the real you, this is the real you, this is what we want."

Mr Turnbull continued: "And, Karl, is it the real you to patronise people who are out of work and are getting the chance to get ahead? I don't think it is. I think you're a fair dinkum Aussie. I think you've got compassion and I think you know that my job is to ensure that more Australians have the chance to get ahead and realise their dreams."

Mr Turnbull's proposed solution to the dual citizenship crisis - a measure compelling all MPs to disclosure relevant documents by the end of the year - has failed to gain Opposition Leader Bill Shorten's support.

In an interview with Seven's Sunrise on Thursday morning, Mr Turnbull lashed out at Mr Shorten, with who he met on Wednesday to outline his plan to resolve the crisis.

After the meeting, Mr Shorten said he would not support the Prime Minister's plan as it stood, insisting MPs should be given five days - rather than three weeks - to produce their documentation, and dismissing the need for Parliament to be recalled to deal with the issue before Christmas.

"He's not being fair dinkum," Mr Turnbull told Sunrise. "He wants to exploit this issue. He wants to prolong it. He does not want to resolve it."

Since the High Court eliminated five sitting parliamentarians last month, doubts have been raised about several more, including Coalition MPs whose loss at any byelection would endanger the government's fragile majority.

Mr Turnbull leaves Australia on Thursday for a week-long trip through Asia that will take in the APEC leaders' summit and the East Asia Summit.

Foreign Minister Julie Bishop will be Acting Prime Minister.
