Now investigators in NSW are licensed pursuant to the Security Industry Act 1997 which defines a private investigator as a person who is employed or engaged for the purposes of either or both of the following:

  • (a) the investigation of persons, being any activity carried out by a person on behalf of a second person (not being his or her employer) that involves finding a third person or investigating a third person’s business or personal affairs,
  • (b) the surveillance of persons, being any activity carried out by a person on behalf of a second person (not being his or her employer) that involves the surveillance of a third person.

Private inquiry agents are now known as private investigators and are regulated by the Security Licensing Enforcement Directorate (SLED) under the Security Industry Act 1997. Private investigators require a Class 2E (Private Investigator) security operative licence to carry on investigation or surveillance activities, or a Master security licence to carry on business in either or both of activities.

To be eligible for a Class 2E security licence, an applicant must have completed CPP30619 Certificate III in Investigative Services, and must provide their qualifications within 42 days of lodging their application.

A Master security licence authorises the holder to provide a specified number of licensed operatives on any one day to carry on security activities.

Note that from 8 June 2022 SLED is exempt from Automatic Mutual Recognition legislation.
