Is a Nationally Co-ordinated Criminal History Check suitable for multiple purposes/jobs?

In short, no. A NCCHC is not suitable for reuse for multiple purposes. For example, a check conducted for the purpose of becoming a volunteer netball coach cannot be used later to apply for a job as an administration officer. This is because the purpose identified on the NCCHC application is used to determine what (if any) police information is released, based on the various state and territory spent convictions legislation and police information release policies that apply. Additionally, they  are considered a ‘point in time’ check. Charges or convictions that occur after the check result has been issued are not captured on the applicant’s existing NCCHC, deeming the result unsuitable for re-use. This is the same if you apply directly through Police.
