The Queensland MP hopes the Australian will be returned home and wants to verify reports that his health is failing Mr Christensen says it is a "crazy situation" that Mr Assange charged under US laws when he is not a US citizen or resident

"It's about the principle of someone who's published information on the internet and fallen afoul of laws [in a country] that they're not a citizen of, that they actually haven't set foot in," Mr Christensen said.

"You've got to question how that is possible. That's a crazy situation that I don't think most Australians would actually agree with."

The Mackay-based Member for Dawson is co-chair of a cross-party Parliamentary Working Group, a role shared with independent MP Andrew Wilkie, questioning whether the Australian citizen should be forced to face espionage charges in the United States.

If found guilty in the US, Mr Assange faces a maximum sentence of 175 years in jail.

But Mr Christensen said WikiLeaks had acted in the public interest when it published classified information, including diplomatic cables leaked by US intelligence analyst leaked by US intelligence analyst Chelsea Manning in 2010.

"He has published information that may have been sensitive in the United States, but he wasn't in the United States when he published it, nor is he a citizen of the United States," Mr Christensen said.

"So, I question how someone can fall foul of a law when they are not a citizen or resident of that country."

Determined to 'see and talk' with Assange

Mr Christensen said the working group would seek permission to visit Mr Assange in order to determine what support they can provide.

Its members have reached across the political divide, with Greens leader Richard Di Natale, Adam Bandt and Peter Whish-Wilson joining Centre Alliance MPs Rebekha Sharkie and Rex Patrick, plus independent MP Zali Steggall.

It comes after former deputy prime minister Barnaby Joyce also called for the Federal Government this month to step in and try to stop the Australian being extradited from the United Kingdom to the US on espionage charges.

"I think that it's right that interested members of Parliament from Julian Assange's home country should be able to see and talk with him," Mr Christensen said.

"I certainly will be putting that request to the British Government.

"What I'd like to know is whether poor treatment [may have affected] his poor state of health and [how] the circumstances of his jailing have impacted on that.

"I'd like to know that by looking at him and talking to him myself."

'His mental health is suffering terribly'

It follows a challenging period for Mr Assange and his legal team, whose request to have his hearing postponed was denied by Judge Vanessa Baraitser in London earlier this month.

Spokesperson for lobby group Bring Assange Home, Louise Bennet, said the whistleblower's health has deteriorated dramatically since being arrested seven months ago at the Ecuadorian embassy in London.

"He's in a really horrific situation where his mental health is suffering terribly," Ms Bennet said.

"I understand he's in solitary confinement. He's not allowed to speak to anyone and he's in this situation 23 hours of the day.

"A lot of people that have been working with him closely have said they're not sure he will survive the process if it drags out too long, let alone if it goes to the US, which is a death sentence for him."

Mr Christensen said his message to Mr Assange was simple.

"I'd just like him to know that there are people fighting for him back in Australia and are fighting for the principles of freedom that underpin his case. It is my hope that he is returned to Australia," he said.

"Before the inception of this working group I had made contact with people in my Government and the British Government about this.

"They probably weren't going to listen to me — a little, old backbencher from North Queensland — but I wanted it on record that I thought there was something incredibly wrong going on."

The next case management hearing will be held on December 17.
