Uploaded 55 years to the day this is a film shot by Australia's internal intelligence agency ASIO of the National Congress of the Communist Party. It takes place in Sydney and the camera is looking at the corner of Sussex St and Sussex lane. This film is unusual in that ASIO have added sound in the form of a commentary in which an officer identifies the persons of interest captured on camera. The film would then have been shown on a regular basis to ASIO staff to enable them to identify persons of interest in the street. This surveillance film now forms part of the documentary series PERSONS OF INTEREST.
