27.1 In this chapter, the ALRC recommends that a ‘Data Quality’ principle, applicable to agencies and organisations, should be included in the model Unified Privacy Principles (UPPs). The ALRC considers a number of changes from the present data quality obligations set out in the Information Privacy Principles (IPPs) and National Privacy Principles (NPPs). In particular, it recommends that agencies and organisations should take steps to ensure that the personal information they collect, use and disclose is ‘relevant’. The ALRC also considers the interaction between the ‘Data Quality’ principle and other obligations set out in the model UPPs.
