Julian Assange, founder of WikiLeaks, returns to Australia after pleading guilty to one charge of espionage in a Saipan court and subsequently being released by the United States Department of Justice.

Julian Paul Assange is an Australian editor, publisher, and activist who founded WikiLeaks in 2006. He came to international attention in 2010 after WikiLeaks published a series of leaks from Chelsea Manning, a United States Army intelligence analyst: footage of a U.S. airstrike in Baghdad, U.S. military logs from the Afghanistan and Iraq wars, and U.S. diplomatic cables. Assange has won over two dozen awards for publishing and human rights activism.

WikiLeaks is a non-profit media organisation and publisher of leaked documents. It is funded by donations and media partnerships. It has published classified documents and other media provided by anonymous sources. It was founded in 2006 by Julian Assange. Kristinn Hrafnsson is its editor-in-chief. Its website states that it has released more than ten million documents and associated analyses. WikiLeaks' most recent publication of original documents was in 2019 and its most recent publication was in 2021. From November 2022, numerous documents on the organisation's website became inaccessible. In 2023, Assange said that WikiLeaks is no longer able to publish due to his imprisonment and the effect that US government surveillance and WikiLeaks' funding restrictions were having on potential whistleblowers.

A plea bargain, also known as a plea agreement or plea deal, is a legal arrangement in criminal law where the defendant agrees to plead guilty or no contest to a charge in exchange for concessions from the prosecutor. These concessions can include a reduction in the severity of the charges, the dismissal of some charges, or a more lenient sentencing recommendation. Plea bargaining serves as a mechanism to expedite the resolution of criminal cases, allowing both the prosecution and the defense to avoid the time, expense, and uncertainty of a trial. It is a prevalent practice in the United States, where it resolves the vast majority of criminal cases, and has been adopted in various forms in other legal systems worldwide.
