The field of sexual homicide research is relatively recent, with many existing studies limited by small sample sizes and sampling bias. In Australia and New Zealand specifically, only one study to date addresses this phenomenon but there is a lack of comprehensive descriptive data. This study aims to fill this research gap using a representative sample gathered from public legal databases. A total of 118 cases of sexual homicide offenders are described to create a portrait of this type of offender, their victims and their offence behaviour. Findings are similar to those found in other large samples from the UK, Canada and Germany. Because this crime is rare and practitioners tend to have limited experience of them, the findings of this research have the potential to inform investigative, criminal justice and clinical practice.

性凶杀研究领域相对较新，许多现有研究受到样本量小和抽样偏差的限制。特别是在澳大利亚和新西兰，迄今为止只有一项研究解决了这一现象，但缺乏全面的描述性数据。本研究旨在使用从公共法律数据库中收集的代表性样本来填补这一研究空白。总共描述了 118 起性杀人犯罪者的案例，以创建此类犯罪者、他们的受害者和他们的犯罪行为的画像。发现与来自英国、加拿大和德国的其他大型样本中的发现相似。由于这种犯罪很少见，而且从业人员往往经验有限，因此这项研究的结果有可能为调查、刑事司法和临床实践提供信息。
