To achieve optimal outcomes from its new or improved national IT systems, CrimTrac had worked hard for a new and better culture of information sharing between police services. Regular and informative liaison characterises CrimTrac's "modus operandi" with police and strong arguments accompany all CrimTrac business cases where police services may be asked to contribute or share information. The impact of the Commonwealth Privacy Act 1988 is also taken into account through the requirement for all new projects that involve the national sharing of sometimes sensitive and usually confidential personal information to prepare a privacy impact assessment.
