Domestic/family violence (DFV) and child protection co-occurrence of risk is common, with related homicides remaining a grave public concern. Recognising and prioritising high-risk cases that pose a lethal risk remains a complex challenge for practitioners across a range of services and legal jurisdictions. There are significant gaps in practice knowledge about how to assess and respond to high-risk cases involving child protection and DFV concerns, while working safely and effectively. This paper reports on qualitative research conducted with practitioners from a range of justice and service delivery organisations in Queensland, Australia. A community of practice, supported by the U.S. based Safe & Together Institute, provided the forum for data to be collected on participants’ reflections and observations. An action research framework was employed to connect practice learning into research data through an iterative cycle of reflection and review. Ethnographic note taking was used to document arising policy and practice issues. Discussions in the CoP were also recorded and transcribed verbatim. Thematic analysis was undertaken combining inductive and deductive techniques. Key findings include: learning from and partnering with women; applying a perpetrator pattern-based approach in high-risk cases; engaging with men as fathers; and improving the role of the judicial system. Practice needs to be informed by centring the victim/survivor perspective, which requires a collaborative approach while maintaining system integrity to hold the perpetrator within system responses to ensure accountability. There are important learnings for developing service sector responses and future research on high-risk cases.

家庭/家庭暴力（DFV）和儿童保护并存的风险很普遍，相关的凶杀案仍然引起公众的严重关注。对于各种服务和法律管辖区的从业人员来说，识别和确定具有致命风险的高风险案例仍然是一项复杂的挑战。在如何安全有效地开展工作的同时，有关如何评估和应对涉及儿童保护和DFV问题的高风险案件的实践知识存在很大差距。本文报告了与来自澳大利亚昆士兰州各种司法和服务提供组织的从业人员进行的定性研究。在美国安全与共同研究所的支持下，一个实践社区为收集有关参与者的思考和观察数据提供了论坛。采用了行动研究框架，通过反复的反思和复习，将实践学习与研究数据联系起来。民族志笔记被用来记录新出现的政策和实践问题。还记录了CoP中的讨论并逐字记录。结合归纳和演绎技术进行主题分析。主要发现包括：向妇女学习和与妇女合作；在高风险案件中采用基于犯罪者模式的方法；与男人作为父亲交往；并改善司法系统的作用。需要通过以受害人/幸存者的观点为中心来告知实践，这需要一种协作方法，同时保持系统完整性，以使肇事者在系统响应之内，以确保责任制。
