It is possible that some wholly-secret trials occurred in Australia during
World War I or
World War II. In the 21st century, several secret trials have occurred or are set to occur in
Australia: • In 2018, "
Witness J" was tried and imprisoned by the Australian government in near-total secrecy. The existence of Witness J was discovered only by chance by a judge, and the scant details were reported to the media. The Attorney General of the
Australian Capital Territory, where Witness J was imprisoned, was not aware of the case. Witness J is a former employee of one of Australia's intelligence agencies, but the identity and alleged crimes are still not public. Independent National Security Legislation Monitor James Renwick said that the level of secrecy in Witness J's case was "unprecedented". • From 2018 to 2021, the lawyer
Bernard Collaery and "Witness K" were prosecuted by the Australian government with a high degree of secrecy, and part of their upcoming trial will be held in secret. The Liberal-National Coalition government of
John Howard had helped secure the independence of impoverished
Timor Leste from
Indonesia. Negotiations were underway over fossil fuel deposits located in the sea between Timor Leste and Australia. The Howard government spied on the new Timor Leste government, and used that as leverage in negotiations to aid Australian company
Woodside Petroleum. Collaery and Witness K are accused of sharing this with the Australian media and the Timor Leste government. Collaery was Witness K's lawyer at the time. Witness K has pleaded guilty, while Collaery has not. Indictments against Collaery were dropped on 7 July 2022 by new Attorney-General
Mark Dreyfus SC. • From 2018 to 2021, the former military lawyer
David McBride was prosecuted by the Australian government for leaking details of alleged
war crimes committed by Australian soldiers in Afghanistan. McBride reported the crimes to superiors in the
Australian Defence Force but felt that the evidence was not being taken seriously. He went to the
Australian Broadcasting Corporation, which in 2017 published a series of articles on the killings and corpse-mutilations called "The Afghan Files". Then, the military began to investigate the war crimes, which led to the 2020
Brereton Report. Part of McBride's upcoming trial will be held in secret. On 14 May 2024, McBride was sentenced to 5 years and 8 months in prison, with a non-parole period of 2 years and 3 months. ==Soviet Union==
