This report presents the results of a performance audit of the Australian Department of Social Services’ (DSS) success in implementing a national plan to reduce violence against women and children. The audit found that while DSS had established effective governance arrangements to support implementation of the plan, the effectiveness in implementing the plan was reduced by a lack of attention to planning implementation and measuring performance. While the Department’s funding and actions were aligned with the plan’s key priorities and DSS had established the two mechanisms required to improve the evidence base, the Department could not demonstrate that the actions taken were prioritised based on available evidence, or that they were collectively contributing to the outcomes of the national plan. The Auditor-General noted it was necessary to better target research activities towards projects that identify what works for whom and in what circumstances. Five recommendations were made to address these issues.
