Six 'peace pilgrims' who trespassed at Australia's top secret military intelligence base Pine Gap last year could face up to seven years in jail.
The anti-war activists were this month found guilty of unlawful entry at the joint US defence facility near the Northern Territory's Alice Springs, where they were found chanting, praying, and playing music.
Queenslanders Jim Dowling, Franz Dowling, Andy Paine, Tim Webb, Margaret Pestorius and Paul Christie will appear for sentencing in the Brisbane Federal Court on Monday.
When Mr Christie was arrested he was found with a Tibetan singing bowl, a silver goblet, a ceremonial rattle, a red cockatoo feather, a kangaroo skin, a prayer shawl and a pocket knife.
Mr Webb was also charged with filming during the incident on September 29, 2016, with the group representing themselves in court.
The Christians argue their action to disrupt the spy base was necessary to stop atrocities escalating the war on terror.
"It is pivotal in the operation of the US drones program responsible for killing innocent people in Afghanistan, Pakistan, Somalia, Yemen, Syria and Iraq," Ms Pestorius said.
"People are dying every day in these wars and Australia is aiding and abetting war crimes."
Mr Paine added that they have no regrets and pledged to continue resisting Australia's involvement in US-led wars.
Melbourne University professor Richard Tanter, who appeared as a witness during the trial, said Pine Gap supplies geolocation data that is essential for US drone strikes.
"In the case of Pakistan, Somalia and Yemen, countries with which neither Australia nor the US are at war, this makes Australia complicit in illegal extrajudicial killings or assassinations," he said.
"Pine Gap has a critical role in US nuclear war operations, battlefield operations in wars in Iraq, Syria and Afghanistan, and in a possible second Korean war."
Experts say Pine Gap is expected to play a role in any American intervention or interception of North Korean missiles, but is not likely to be on the rogue state's hit list.
