  HISTORY OF FINGERPRINTS IN AUSTRALIA  

In 1901, Mr. Sam McCauley, Deputy Controller of Prisons and Inspector of Prisons in New South Wales, investigated the use and classification of fingerprints at New Scotland yard and on his return recommended that fingerprinting and classification under the Henry System be introduced to New South Wales Gaols.

In 1902, fingerprinting commenced in New South Wales Gaols, and a Fingerprint Bureau was established in the Darlinghurst Gaol under the Direction of Sam McCauley. Following its successful introduction, it was recommended that the system be introduced in the other States of Australia and New Zealand.

In 1903, Senior Sergeant W.H. Childs, of the New South Wales Police Force, received training from Mr. McCauley and also spent several weeks at the Darlinghurst Gaol Bureau. In June 1903, the Prisons Department handed over approximately 6,000 copies of fingerprint impressions to the New South Wales Police Department. The New South Wales Police Fingerprint Bureau was established at the Detectives' Office of Police Headquarters, with Senior Sergeant Childs as Officer in Charge.
