Turnbull praises Trump economic leadership

Malcolm Turnbull has praised Donald Trump as having delivered economic leadership, as the US president prepared to deliver his first State of the Union address.

Mr Trump is set to deliver the landmark speech to the US Congress at 1pm AEDT on Wednesday.

"Donald Trump is delivering on economic leadership, that's for sure," Mr Turnbull told News Corp's Miranda Devine Live program on Monday.

"I don't want to buy into US politics but ... you only have to look at the IMF to see they regard the American tax cuts as being very pro-growth."

Asked what he thought of Mr Trump's tendency to put down his critics, the prime minister said: "You get plenty of criticism in public life, I think you've got to expect it. I'm sure he expected it and he is getting on with the job as he sees best."

Mr Turnbull said he had read Michael Wolff's behind-the-scenes expose of the Trump White House, Fire and Fury, but declined to comment on the "sensational" book.

"These political memoirs - they come and go," he said.

Mr Turnbull said he and Mr Trump had a "very good relationship" and the US-Australian relationship was in good shape.
