The arrest of Ben Roberts-Smith at Sydney Domestic Airport marks a watershed moment in Australian legal and military history. After stepping off a flight from Brisbane, the former Special Air Service Regiment (SASR) soldier was taken into custody, capping a grueling five-year journey to Ben Roberts-Smith’s arrest that has shifted from the halls of civil defamation courts to a high-stakes criminal investigation.
The operation, led by the Australian Federal Police (AFP) and the Office of the Special Investigator (OSI), represents the culmination of an investigation into the conduct of the Australian Defence Force (ADF) that began in 2021. Roberts-Smith, 47, is expected to face five counts of alleged war crime—specifically murder—charges that carry a maximum penalty of life imprisonment.
This case is poised to become the largest war crime prosecution in the history of the Australian Commonwealth. It serves as a stark illustration of the tension between the nation’s highest military honors and the stringent requirements of international humanitarian law.
The trajectory of a decorated soldier
For over a decade, Ben Roberts-Smith was regarded as one of Australia’s most distinguished warriors. His career with the SASR was defined by multiple deployments to Afghanistan, where his actions earned him the nation’s most prestigious awards. In 2006, he was awarded the Medal for Gallantry, and later, in 2011, he received the Victoria Cross for “most conspicuous gallantry” and “valour” during the Battle of Tizak on June 11, 2010.
By 2012, his reputation as a patrol commander was cemented through more than 50 high-risk operations, earning him a Commendation for Distinguished Service. He retired from full-time service in 2013, transitioning into the private sector by forming his consultancy, RS Group Australia. That same year, he was named the Australian Father of the Year, symbolizing a public image of heroism and familial stability.
From defamation to criminal liability
The public perception of Roberts-Smith began to fracture in June 2018, when investigative reports identified an anonymous SAS soldier, referred to as “Leonidas,” accused of war crimes. After an unsuccessful attempt by his legal team to block the reports, Roberts-Smith was named and subsequently launched a massive defamation lawsuit in the Federal Court.
The resulting legal battle was one of the most expensive and exhaustive in Australian history. Over 14 months, the trial spanned 110 days and called 41 witnesses. Although the case was initially delayed by the COVID-19 pandemic, it eventually concluded in July 2022.
In 2023, Justice Anthony Besanko dismissed the defamation claims, ruling that the allegations of war crimes and bullying were substantially true. Crucially, the judge found that, under the civil standard of proof, Roberts-Smith had killed four unarmed Afghan men and violated military rules of engagement. A final attempt to appeal this decision was rejected in September 2025, with total legal costs for the trial and appeal estimated to exceed $30 million.
The Brereton Report and the OSI investigation
While the defamation trial focused on reputation, a parallel administrative inquiry known as the Brereton Report was uncovering systemic issues within the Special Operations Task Group. The report found credible evidence of 23 incidents where 39 Afghan nationals were unlawfully killed by Australian special forces, identifying 25 personnel as potential perpetrators.
This findings led to the creation of the Office of the Special Investigator (OSI) in 2021 to pursue criminal charges. The current allegations against Roberts-Smith stem from two primary periods of deployment in the Uruzgan Province:
- April 2009 (Kakarak): The AFP alleges Roberts-Smith intentionally caused the death of a person on or about April 12, and further alleges he aided or abetted another person in causing a death on the same date.
- September and October 2012 (Darwan and Syahchow): Charges are expected regarding the alleged murder of an individual on September 11, and two further counts related to the death of a person on October 20, including allegations of aiding, and abetting.

The next critical checkpoint will be the formal filing of charges and the first court appearance, where the judiciary will determine bail conditions and the timeline for the prosecution’s evidence. This trial will likely serve as a definitive test of Australia’s commitment to holding its most elite soldiers accountable for actions taken in the field.
