Contact Reporting Scheme

ASIO uses the Contact Reporting Scheme (CRS) to identify hostile activity directed against Australia and its interests, government employees and contractors, and people with an Australian Government security clearance. ASIO also uses the CRS to identify trends, including:

  • what information is of interest to foreign intelligence services;
  • who is interested in the information; and
  • the methods foreign intelligence services are prepared to use to collect information.

ASIO uses this information to formulate threat assessments and security intelligence advice. Threat assessments help agencies understand threats to their resources and formulate appropriate countermeasures to mitigate threats and manage risks.

If an Australian Government employee, contractor or clearance holder has been the subject of contact by a foreign national which meets the reporting criteria, they should report the incident to their Agency Security Adviser (ASA) or equivalent. The ASA will provide employees with a Contact Report form and send the completed form to on relevant systems.

Employees should report contact, either social or official with:

  • any foreign national, regardless of geographic location, when contact seems suspicious, persistent or unusual in any respect, or becomes ongoing; For example: exchanging contact details (i.e. phone number/email/Facebook/Instagram) and/or foreign nationals who are likely to engage with the employee on a regular basis due to their relationship with a friend or a family member.
  • any Australian nationals where the contact is suspicious, unusual or persistent; and/or; For example:an Australian national who consistently asks-directly or indirectly - about specific information relating to the activites of the employee's role, or agency/company even when questions are deflected or the topic has changed.  Persistent contact could include persons who continue to contact the employee even after attempts have been made to disengage contact.
  • any individual or group, regardless of nationality, who seeks to obtain information they do not have a need to know.  For example: an employee asking colleagues probing questions relating to activities or capabilities they do not have a demonstrated need to know and/or appropriate clearance/briefings.
