How Police Identified Over 120 Families in Major Child Abuse Case

The Australian Federal Police have reached out to 121 families in Australia and overseas after identifying their children in child abuse material. The material was allegedly created by Hamish Tait, a 35-year-old former Sydney childcare worker now facing 329 charges The Guardian.

What the charges allege

Tait is accused of abusing 136 children over 16 years. The charges break down into specific categories: 162 counts of producing child abuse material, 24 counts of using a child under 14 to produce it, 22 counts of aggravated use of a child under 14 for the same purpose, and 18 counts of intentionally sexually touching a child under 10. The aggravated production charges carry a maximum penalty of 20 years' imprisonment The Guardian.

As of July 2026, 22 of the 136 alleged victims remain unidentified. That number matters because police are likely to contact more families as those identifications happen.

How the investigation unfolded

Operation Moonbi, as police named it, began in June 2025 when an online tip flagged a user uploading abuse material. Investigators then analyzed 2.4 million electronic files over a 12-month period using 12 search warrants. One warrant was executed at a property in Glossodia in Sydney's north-west. Tait was arrested and charged in July 2025, and his childcare accreditation was suspended immediately.

According to acting commander Luke Needham, all alleged offending occurred in New South Wales, with some in South Australia. The abuse material was allegedly shared overseas three times. Police identified 62 early childhood education facilities where Tait worked or visited during his 16-year employment history—concentrated in Sydney's north-west—and allege he committed multiple offences at five of them: four childcare centres and one private business of his own.

Why the numbers are so large

The scale of this case sets it apart from typical childcare abuse prosecutions in Australia. Because Tait worked across 62 different sites over 16 years, police must contact families whose children attended any of those centres during his tenure, not just the five locations where the worst offences allegedly occurred. Checking enrolment records against 16 years of employment history across dozens of centres is far slower and more thorough work than confirming abuse at a single location would be. That explains why 121 families have been contacted rather than a smaller number tied only to the five high-allegation sites.

For law enforcement, analyzing 2.4 million files sits near the upper limit of what AFP child exploitation taskforces have processed in one operation. That reflects both the long offending period and the international reach of the alleged material-sharing. The involvement of overseas families also means the AFP has activated its standard cooperation channels with foreign law enforcement through tools like INTERPOL's image-comparison databases and bilateral agreements once material is matched to identified children.

The identification challenge ahead

The remaining 22 unidentified victims present a typical problem in historical abuse cases. The easiest identifications tend to surface first—those with clearer imagery, distinctive settings, or connections to known missing children. The remaining victims may be harder to identify because their material offers fewer visual clues. The AFP has seen this pattern before in large-scale operations.

The case now moves toward committal proceedings in the NSW court system, where 329 charges will likely make the prosecution lengthy. Police have not said whether additional charges will emerge as the remaining victims are identified or as further analysis of the 2.4 million files continues. The AFP has also not indicated when it expects the identification process to finish.
