Ex-Trainee Doctor Pleads Guilty to Secretly Filming Hundreds in Melbourne Hospital Toilets

Detailed counts by site show how heavily Cho targeted each hospital: 2185 intimate images of 541 victims at Austin Hospital (April 2–July 7, 2025); 277 victims in 720 images at Royal Melbourne Hospital (Oct 12, 2024–Jan 7, 2025); 50 victims in 81 images at Peter MacCallum Cancer Centre (Oct 10–31, 2025), plus 104 intimate videos and 3,424 photographs of a single victim (Oct 22, 2020–Sept 25, 2021).
Initial discovery of the crime included a nurse and maintenance workers finding a camera phone recording inside a mesh bag in a hospital toilet, with about three hours of footage showing Cho setting up the device before five others used the bathroom.
Investigators located thousands of videos at Cho’s home and described the scale of the offence as 'thousands of intimate images' with about 4,500 videos on devices at one point, alongside claims he had categorised at least 460 women by name and hospital.
Rolling up charges condensed hundreds of victims into fewer charges, and the next court step is a County Court appearance on November 23 for a three-day pre-sentence hearing during which victims can provide statements about how the crimes affected them.
Beyond the criminal charges, Cho remains barred from practicing by the Australian Health Practitioner Regulation Agency (AHPRA) and has been released on bail with conditions, including a $50,000 surety and mandatory medical treatment, while under ongoing psychological assessment.
A junior doctor has pleaded guilty to secretly filming hundreds of colleagues in hospital toilets across Melbourne, in one of Australia's most serious workplace privacy crimes. Ryan Yi Cho, 29, admitted hiding a phone inside a mesh bag in staff bathrooms at three major hospitals, capturing thousands of intimate images without consent, according to 7News.
Cho faced 13 charges in total, including producing an intimate image, installing a device, and stalking. Prosecutors say about 4,500 videos were found on his devices, and he had catalogued at least 460 women by name and hospital, according to Merimbula News Weekly.
The crimes came to light when a nurse and maintenance workers spotted a camera phone recording inside a mesh bag in a hospital toilet. The device had captured about three hours of footage. It showed Cho setting up the camera before five other staff members used the bathroom, according to Muswellbrook Chronicle.
Police then launched a broader investigation. They searched Cho's home and found thousands more videos. The scale of what they uncovered was staggering — prosecutors described it as involving 'thousands of intimate images' spread across multiple devices.
Cho targeted staff at the Austin Hospital, the Royal Melbourne Hospital, and the Peter MacCallum Cancer Centre. At Austin Hospital alone, he filmed 541 victims and captured 2,185 intimate images between April 2 and July 7, 2025. At Royal Melbourne, 277 victims appeared in 720 images between October 2024 and January 2025, according to Nyngan Observer.
At the Peter MacCallum Cancer Centre, 50 victims appeared in 81 images over three weeks in October 2025. Prosecutors also identified one single victim who appeared in 104 intimate videos and 3,424 photographs taken over roughly a year, between October 2020 and September 2021.
Because there were so many victims, the court condensed hundreds of individual offences into rolled-up charges. This is a legal process that groups similar crimes together into a single count. Many of the victims watched the proceedings online, according to Blue Mountains Gazette.
Cho's next court date is November 23, when a three-day pre-sentence hearing begins at the County Court. During those hearings, victims can submit statements about how the crimes affected their lives. Sentencing is expected to follow later in the year.
Cho has been stood down from clinical duties and is barred from practicing medicine. The Australian Health Practitioner Regulation Agency, known as AHPRA, which oversees medical licences in Australia, imposed the ban. He cannot work as a doctor while the case proceeds, according to 7News.
He was released on bail under strict conditions. Those include a $50,000 surety — a financial guarantee paid to secure his release — and a requirement to undergo ongoing psychological assessment and mandatory medical treatment. He must also comply with other conditions while awaiting sentencing.
