STAN GRANT, PRESENTER: So, Australians will go to sleep tonight and wake in the morning to a new reality. Donald J Trump will officially be the President of the United States. It has been unlikely triumph for the billionaire reality television star who has seen off his opponents and confounded pundits with the slogan Make America Great Again.

Trump has made it clear this will be an unorthodox presidency. He does things his way.

Take the media. Trump has used his Twitter account to deride his critics and he's declared open season on some journalists and the world's most powerful news organisations.

Here is Matt Peacock.

DONALD TRUMP: We are going to take on the big media, big business and big donors that are bleeding our country dry.

MATT PEACOCK, REPORTER: For the campaigner Donald Trump, mainstream media was the enemy and his supporters agreed.

CROWD (Chanting): USA, USA.

DONALD TRUMP: Our great movement, powered by everyday citizens, will overcome the sickness that is plaguing our politics and our media.

And I'll tell you what. Our media is, indeed, sick and it's making our country sick and we're going to stop it.

Press are liars. They are terribly people.

They are really, really bad people.

Sit down. Sit down.

REPORTER: You cannot deport 11 million people. You cannot deny citizenship. I am a reporter, don't touch me, sir. Don't touch me, sir. You cannot touch me.

MATT PEACOCK: At times the anti-media campaign rhetoric turned to violence like this attack on veteran Times photographer, Chris Morris.

NICK O'MALLEY, FORMER US CORRESPONDENT, FAIRFAX MEDIA: It is combative, it is often ugly. I have been at rallies where it is almost like a pantomime.

Part way through his performance, he turns on the media and starts talking about how they are dishonest and then the crowd turns around and they throw bottles.

BRUCE WOLPE, FORMER DEMOCRATIC ADVISER: Donald Trump supporters, white working class Americans under economic threat feel the media is an enemy of theirs.

CROWD (Chanting): USA, USA.

MATT PEACOCK: Journalist Nick O'Malley covered the Trump campaign for Fairfax Media.

NICK O'MALLEY: There was the constant threat of being expelled from his rallies. His own security who followed you around and if they didn't like your behaviour or what you are asking, they would throw you out.

And now that he is about to walk into the White House, he is reshaping the press corp itself, deciding who will get access and who will not.

And it looks as though he's doing that differently than has been done in the past.

UNKNOWN: The fact BuzzFeed and CNN made the decision to run with this unsubstantiated claim...

MATT PEACOCK: Already the stage has been set at the President-elect's first media conference where CNN and Donald Trump battled over who would get the next question.

REPORTER: Since you are attacking us, can you give us a question?

DONALD TRUMP: Go ahead.

REPORTER: Mr President-elect.

DONALD TRUMP: Go ahead, go ahead.

REPORTER: Mr President-elect. Since you are attacking ...

DONALD TRUMP: Not you, not you, your organisation is terrible.

REPORTER: You are attacking our news organisation.

DONALD TRUMP: Your organisation is terrible.

REPORTER: Give us a chance to ask a question sir.

DONALD TRUMP: Go ahead, quiet. Quiet.

REPORTER: Mr President-elect, can you say categorically, Mr President-Elect ...

DONALD TRUMP: She's asking a question. Don't be rude. Don't be rude.

REPORTER: Mr President-elect, can you give us a question, you are attacking us ...

DONALD TRUMP: Don't be, no, I'm not going to give you a question.

REPORTER: Can you state categorically ...

DONALD TRUMP: You are fake news. Go ahead.

REPORTER: Sir, can you state categorically that nobody ...

LAURA INGRAHAM, POLITICAL COMMENTATOR: The press has a terrible reputation right now, let's face it. Most of them got this election wrong from the beginning.

They were not tuned in to the pulse of the American people.

Most Americans think the media was rooting for Hillary and I think they have a lot to prove to the public that they are going to cover this presidency fairly.

NICK O'MALLEY: By convention, the President gives access to, if not the White House press corp, then to a pool reporter at all times and he shows no sign of doing that, he shows no interest in doing that.

It is only a convention, he can do what he likes.

To try and counter that, the press corp has written an open letter to him saying they will stand united in pursuing access and if he doesn't give them access, then they will turn to his government and look for leaks and look for other sources and they will do that.

But it's already a very combative relationship as a result.

MATT PEACOCK: Donald Trump has already shown he has an alternative - at least 18 million followers on Twitter.

BILL O'REILLY, FOX NEWS: I used to think all this tweeting hurt Donald Trump but now it's a necessity because he can expect to be attacked every day. He must have a rapid defence mechanism in his own words and Twitter provides that.

JIM ANDERSON, CEO, SOCIALFLOW: He tweets maybe 125 to 150 times a month on average. The real impact though comes from the media coverage of what he says.

And let's not forget that that's one of the important parts of his candidacy and I think will be one of the important parts of his presidency, is he says something provocative on Twitter, yes, a lot of people hear about it but the amount of media coverage that comes in and provides the amplification to that message is huge.

Three hundred times at least by comparison just on Twitter alone.

MATT PEACOCK: Now it will be President Trump, the question is: Will the media change or will he?

NICK O'MALLEY: The Washington Post has just hired dozens of new reporters to investigate his administration, to cover his administration. The New York Times is ramping up its coverage.

BRUCE WOLPE: The media will not make or break him. The media will report on him. What makes the difference is whether President Trump can deliver on the promises to the people who support him. If he disappoints them, he will fail.
