Australian Catholic University

What you'll study

The Diploma provides a broad grounding in how societies understand and respond to crime. Core subject areas typically include criminological theory, the structure and operation of criminal justice institutions, crime prevention, and contemporary issues such as youth offending, victimology and restorative justice. You will also study research methods for the social sciences and develop academic skills in writing, critical thinking and ethical practice.

Study is usually delivered as a sequence of short, focused units combining lectures, tutorials and applied learning activities. Typical module topics you can expect include:

• Introduction to Criminology and Crime Typologies
• Criminal Law and the Justice System
• Policing and Community Safety
• Youth Justice and Diversionary Responses
• Victims, Restorative Justice and Corrections
• Research Methods and Data in Criminology
• Ethics, Policy and Indigenous Perspectives on Justice

Entry requirements

Entry is designed to be accessible to both recent secondary-school completers and mature-age applicants. Typical requirements include a completed secondary qualification (senior secondary certificate) or an equivalent vocational qualification. Applicants with relevant work experience in community services, justice or allied fields may be considered through alternative entry pathways. International applicants must meet Australian tertiary English language requirements and provide recognised academic documentation.

ACU also offers pathway arrangements so successful completion of the Diploma can provide credit or direct entry into the university's undergraduate criminology or related degrees; applicants should consult ACU admissions for specific credit-transfer policies.

Career prospects

The Diploma equips graduates with foundational knowledge and transferable skills useful in entry-level roles across the justice and community sectors. Typical employment outcomes include support and administrative roles in community justice agencies, victim support services, youth support programs, court administration, and community advocacy organisations. Many students use the Diploma as a stepping stone to a Bachelor degree, which opens further careers in policing, corrections, probation and parole services, social work, forensic practice and policy roles.
