In 2026, the Offender Database recorded that 69-year-old William “Rob” Gilfillan—a former PE teacher at Traralgon High School—was found guilty of a series of “disgusting” sexual assaults dating back to the 1980s. Gilfillan appeared via video link from Barwon Prison, where he is currently serving Australia’s longest sentence for child sex abuse. It was reported that the investigation established Gilfillan used his position of authority in the school gymnasium to target and sexually penetrate a 15-year-old girl and indecently assault another student.
The investigation established that Gilfillan used “sadistic” methods to facilitate his abuse, including using callipers to pinch the intimate parts of a student’s body under the guise of preparing for a “slimmers weekend” camp. the prosecution reported that Gilfillan has occupied a position of extreme trust as a teacher, which the court heard was a significant aggravating feature of his crimes. One survivor provided a “heartbreaking” impact statement, detailing “lost decades” spent battling alcohol misuse, bulimia, and body dysmorphia as a direct result of his actions.
Judicial Findings and Investigative Detail
The court reported that Gilfillan is already serving a 48-year sentence with a 36-year non-parole period for the rape and torture of his own daughter in New South Wales. The investigation established that he has shown “not a modicum of remorse” and continues to deny all charges against him despite overwhelming evidence. The prosecution reported that since he was first jailed in 2016, his refusal to admit his guilt demonstrates that he has failed to rehabilitate himself and remains a “depraved” threat to society.
Judge-led proceedings at the Victoria County Court concluded with Chief Justice Amanda Chambers hearing that Gilfillan will not even be eligible for parole for his prior crimes until he is 96 years old. For his actions at Traralgon High School and the “selfish and sadistic” reasons behind his offending reported, the prosecution has pushed for a significant sentence to be served on top of his existing term. The judge noted the survivor’s courage in finally speaking out after decades of shame, with final sentencing for these 1980s crimes scheduled for June 2026.

Monitoring and Public Protection
Gilfillan is managed as one of Australia’s highest-risk dangerous sex offenders within the maximum-security prison system. Due to the nature of his conduct—specifically his “serial, sadistic targeting of children under his care and his own family members”—his management is a national priority for the Australian Criminal Intelligence Commission. Authorities state that his history identifies him as a man who utilised institutional structures to gain access to victims, requiring permanent exclusion from any form of social reintegration or proximity to minors.
As a registered sex offender for life, the 69-year-old’s details are permanently logged on the Australian National Child Offender Register. Authorities state that the lifting of a decade-long media suppression order in December 2025 was a vital step in ensuring public transparency regarding his “vile” history. Any future sentencing will reflect the “prolonged psychological destruction” he caused his victims, ensuring that the man described as a “disgusting paedophile” remains behind bars for the remainder of his natural life.
QUESTION – Given that the offender is already serving a sentence that likely exceeds his natural life, do you believe that “Cumulative Sentencing” for non-recent crimes is necessary to provide survivors with the formal judicial recognition that their specific trauma has been accounted for by the state?
