Australia’s Most Decorated Veteran Ben Roberts-Smith Loses Final Legal Battle

Australia’s High Court has ended Ben Roberts-Smith’s last chance to overturn devastating legal findings against him. The ruling means the most decorated living Australian soldier remains branded, in civil law, as responsible for unlawful killings and serious misconduct in Afghanistan. It is the final chapter in a six-year legal fight that began as an attempt to protect his reputation but instead exposed him as the central figure in Australia’s reckoning with its conduct during the war in Afghanistan.

The High Court announced Thursday it would not hear Roberts-Smith’s appeal of a 2023 Federal Court decision that found four murder allegations against him were substantially true. That verdict came after an extraordinary 110-day defamation trial, one of the longest and most expensive in Australian legal history. Three Federal Court judges upheld the findings in 2024, and the High Court’s refusal in 2025 closes off his final legal avenue.

For Roberts-Smith, once celebrated as the embodiment of Australian gallantry, the decision represents a complete reversal of fortune.

From Decorated Soldier to National Icon

Benjamin Roberts-Smith was born in Perth in 1978 and joined the Australian Army in 1996. He rose through the ranks into the Special Air Service Regiment (SASR), Australia’s elite special forces unit. He served in East Timor, Iraq, and Afghanistan, where he earned a reputation for aggressive courage under fire.

In 2010, during a mission in Afghanistan’s Kandahar province, Roberts-Smith led an assault against Taliban machine-gunners. His actions were credited with saving his platoon, and in 2011, he received the Victoria Cross for Australia, the nation’s highest award for gallantry. He had already earned the Medal for Gallantry in 2006 and a Commendation for Distinguished Service. These honors made him Australia’s most decorated living soldier.

He was hailed as a national hero, the modern face of the Anzac legend.

After leaving the military in 2013, he transitioned into civilian life, taking on leadership roles in the media industry. His public image was that of a war hero who had exemplified bravery in combat and then successfully moved into corporate life.

The Allegations Emerge

That carefully built reputation began to unravel in 2018. The Sydney Morning Herald, The Age, and The Canberra Times published a series of investigative reports alleging that Roberts-Smith had committed war crimes in Afghanistan between 2009 and 2012.

The articles described the killing of unarmed Afghans, assaults on captives, and a culture of intimidation within the SAS.

Roberts-Smith denied the claims. He launched a defamation case against the newspapers, insisting the reports were false and had destroyed his good name. His lawsuit set the stage for an unprecedented courtroom battle that would reveal the hidden world of Australia’s special forces.

The ‘Trial of the Century’

The civil trial stretched across 110 days, involving more than 40 witnesses, including Afghan villagers, a former government minister, and numerous current and former SAS soldiers. Some soldiers described a “code of silence” within the regiment, where misconduct was rarely reported. Others defended their actions as legitimate combat decisions.

The evidence was often contested, with witnesses contradicting one another. Some soldiers were subpoenaed to appear and did so reluctantly. Three refused to answer certain allegations, citing the risk of self-incrimination.

Journalists Nick McKenzie, Chris Masters, and David Wroe, who broke the original stories, called the case “the trial of the century.” It exposed not only the allegations against Roberts-Smith but also the broader culture and internal conflicts within Australia’s most secretive military unit.

The Findings, Appeals, and Final Verdict

In June 2023, Justice Anthony Besanko delivered his judgment. He ruled that four of six murder allegations were proven to the civil standard of balance of probabilities.

Among the findings was that Roberts-Smith had kicked a handcuffed farmer off a cliff, knocking out his teeth, before the man was shot dead. Another Taliban fighter, already captured, was shot at least ten times in the back. His prosthetic leg was later kept as a trophy and used by soldiers as a drinking vessel.

Besanko also found that Roberts-Smith had ordered or agreed to two murders to blood inexperienced soldiers. In addition to these killings, the court found that he had assaulted captives and bullied fellow soldiers.

Two other murder allegations were not proven, nor were claims that he had assaulted a woman with whom he was having an affair or threatened a junior colleague. Even so, the judge concluded the newspapers had largely succeeded in their defense of truth.

The judgment was historic. It was the first time an Australian court had assessed allegations of war crimes committed by the nation’s soldiers.

Roberts-Smith immediately appealed the ruling. In May 2024, three Federal Court judges unanimously rejected his challenge, upholding Justice Besanko’s findings. Then, in September 4, 2025, the High Court confirmed it would not hear a further appeal. That refusal locked in the outcome and left Roberts-Smith with no legal options.

Although he has never faced criminal charges, which require proof beyond reasonable doubt, the civil court findings now define his public legacy.

Wider Reckoning for Australia

The Roberts-Smith case is part of a broader examination of Australia’s military conduct in Afghanistan. A landmark 2020 report recommended 19 current and former soldiers face investigation for 39 unlawful killings between 2007 and 2013.

So far, only one former SAS soldier, Oliver Schulz, has been charged, accused of murdering an unarmed civilian in 2012. He has pleaded not guilty and awaits trial.

The only Australian veteran convicted in connection with the Afghanistan campaign is David McBride, a former army lawyer who leaked classified documents to the media. His disclosures formed the basis of the “Afghan Files” reports published by the ABC in 2017. In 2023, McBride was sentenced to more than five years in prison.

For some observers, Roberts-Smith’s downfall is a precursor to further war crimes prosecutions. War historian Peter Stanley described his case as a “litmus test” for how Australia confronts its military’s actions in Afghanistan.

Once hailed as Australia’s greatest living soldier, Roberts-Smith now stands as the most prominent figure in the nation’s reckoning over its longest war.
