The Australian government says it's committed to the principle of not exposing its citizens to the death penalty as the US moves in on Julian Assange.
Australian consular officials will visit the WikiLeaks founder in a London jail on Friday after he was arrested at the Ecuadorian embassy and promptly convicted of skipping bail.
Supporters fear Assange could face the death penalty if the US succeeds in a bid to extradite and try him over the release of thousands of classified US government documents years ago.
Foreign Minister Marise Payne says Australia remained "completely opposed" to the death penalty.
She said the UK had sought assurances from the US that Assange would not be exposed to death if he was extradited.
"The extradition process itself is a matter between the United States and the United Kingdom, but we have also been provided with that advice from the UK," she told reporters.
"Australia ... is completely opposed to the death penalty and that is a bipartisan position and one which we have continued to advocate."
Senator Payne said the Australian High Commission was seeking to have officials meet with Assange on Friday.
News of the planned jailhouse meeting came as Amnesty International called on the UK not to send Assange to the US if he was at risk of human rights violations.
The group's Europe spokesman Massimo Moratti said those violations might include "detention conditions that would violate the absolute prohibition of torture", and the possibility of an unfair trial followed by possible execution.
"We urge the UK authorities to comply with the assurances provided to Ecuador that he would not be sent anywhere he could face the death penalty, torture or other ill-treatment," he said.
Assange was dragged from the Ecuadorian embassy in London overnight, charged and promptly convicted in court of skipping bail in 2012.
That was the year he sought asylum at the embassy, saying he feared his life could be at risk if he was sent to the US to be tried for the biggest leak of classified government documents in American history.
