PERTH, WA, NOV 4 (Reuters) — WA police have used a facial‑recognition AI to scan 1.3 million images, generating 122 arrests in the first six months of the trial. The rollout, overseen by the Western Australia Department of Justice, marks the largest deployment of biometric surveillance in Australia.

WA Police Facial Recognition Arrests

The trial began in March 2026, targeting high‑crime precincts in Perth, Fremantle and Joondalup. Police reported 5,800 system‑generated alerts; 122 led to charges ranging from drug possession to violent assault. A timeline of key events:

• Mar 15, 2026: Pilot approved under a limited‑scope amendment.
• Apr 1, 2026: First live feed integrated at Perth Central Station.
• Jun 30, 2026: Mid‑trial audit released 3,200 false positives.
• Oct 20, 2026: Public report disclosed 122 arrests.

Operational Mechanics and Accuracy

The AI, supplied by Clearview AI Ltd., cross‑references live CCTV frames with a database of 1.3 million indexed images sourced from driver licences and social media. Independent testing by the Australian National University recorded a true‑positive rate of 87 % and a false‑positive rate of 0.04 %, aligning with police‑reported figures. The system requires a manual review by an officer before any enforcement action.

Legal and Privacy Reactions

Western Australia’s Privacy Commissioner, Julie Bishop, warned that "mass‑scale biometric scanning without explicit consent risks eroding public trust." The Civil Liberties Union of WA filed a class‑action suit alleging breaches of the Surveillance Devices Act 1998. In response, the Department of Justice pledged a quarterly independent audit and a public register of all matches.

Future Outlook and Official Statements

Police Commissioner Mark Simmons said the pilot “has demonstrably reduced repeat offenses in targeted zones.” He indicated plans to extend the system to regional hubs pending legislative review. The state government has commissioned a legislative task force to assess privacy safeguards before any permanent rollout.
