Prime Minister Scott Morrison said any extradition plans had "nothing to do with Australia," and that Assange would receive only standard assistance from Australian consular officials. Tthe 47-year-old would have to face the consequences of any breach of the law in foreign jurisdictions, Morrison said.
Foreign Minister Marise Payne, however, responded to fears from Assange's supporters over his possible punishment in the U.S., saying Australia is "completely opposed to the death penalty." She said Britain had sought assurances from the U.S. that Assange would not be exposed to the death penalty if he was extradited.
Signs of support for Assange emerged in his home country on Friday, where about 30 people marched in central Sydney after gathering outside the British Consulate and calling for the release of a figure they regard as a crusader for truth, and freedom of speech.
Holding signs with messages including "Free Assange — No U.S. extradition," they chanted: "Free the truth; Free Assange; Don't shoot the messenger."
Another small protest in support of Assange took place in Melbourne later on Friday.
Australia's journalists' union, the Media Entertainment and Arts Alliance, also supported calls for Assange's release.
The union's Federal President Marcus Strom said Assange was being pursued for "acts of journalism." Pointing out that WikiLeaks had in 2011 been bestowed with Australian journalism's highest honor, the Walkley Award, Strom said Assange's case was a press freedom issue.
"Julian Assange is being pursued over acts of journalism committed by WikiLeaks ... and that was revealing information that was clearly in the public interest, around atrocities and possible war crimes committed in Iraq and Afghanistan," Strom told the Australian Broadcasting Corp.
Strom said those reports had been published in newspapers such as the New York Times, Britain's the Guardian, and in Australia in the Sydney Morning Herald and the Melbourne Age.
"So on those grounds it becomes a press freedom issue," he said. "It's not a personal issue about Julian Assange."
Strom suggested there'd been less than universal support from journalists for Assange because "as a personality, he's clearly a divisive figure."
"But now that ... the issues are around questions of journalistic principle, people will gain a stronger voice to stand up and call for Julian Assange to be released."
The MEAA awarded Assange, a long-term member of the union, lifelong membership in 2010 as a show of solidarity.
Also on Friday, Assange's mother, Christine Assange, took to Twitter to call for police and prison and court staff to be gentle with her son.
She tweeted he had been "8 years detained WITHOUT charge," and for six years had been "deprived fresh air, exercise, sun," for three years had been "sick/in pain denied proper medical/dental care" and for one year he'd been "isolated/tortured."
"Please be patient, gentle & kind to him," she said.
Assange took refuge in the Ecuadorian Embassy in London in 2012 after he was released on bail in Britain while facing extradition to Sweden on sexual assault allegations that have since been dropped. He refused to leave the embassy, fearing arrest and extradition to the U.S. for publishing classified military and diplomatic cables through WikiLeaks.
Morrison confirmed Assange would receive "normal" consular assistance following a request put by his legal team to the Australian High Commission in London.
"It's the normal consular support that is provided by our missions overseas for people who are going through justice systems," he told Australia's Channel 7 television network. "He will have to face the justice system. When Australians go overseas and if they violate other countries' laws, then obviously they have to face the process for those alleged actions.
"He won't be getting special treatment from Australia. He will be getting the same treatment that any other Australian would get in those circumstances," Morrison said.
