International Relations and Diplomacy is a multidisciplinary field of study that examines how countries, international organisations, non-governmental bodies, and global actors interact with one another. Covering diplomacy, security, governance, political economy, and conflict resolution, these courses equip students with a deep understanding of the forces shaping our world — from trade agreements and human rights to climate change, terrorism, and geopolitical competition. Students explore theoretical frameworks alongside real-world case studies, developing the analytical and communicative skills needed to engage with complex global issues. The field is especially relevant in the Indo-Pacific context, with Australian programs placing strong emphasis on Australia's relationships with Asia, the Pacific, and the wider international community.

These courses are designed for students who are curious about the world, passionate about global justice, international security, or foreign policy, and who want to make a meaningful contribution to shaping Australia's place in the world. Employers of graduates span a wide range of sectors, including the Department of Foreign Affairs and Trade (DFAT), other federal and state government agencies, the Australian Defence Force, United Nations agencies, international NGOs, think tanks, multinational corporations, international media organisations, and university research centres. Whether a student is drawn to frontline diplomacy, policy advisory work, development assistance, or international business, this field of study provides the intellectual foundation and professional networks to get there.

For undergraduate programs such as a Bachelor of International Relations or Bachelor of International Studies, Australian domestic students typically need to complete Year 12 with an ATAR score in the range of 75–90, depending on the institution and the level of demand for the program. Some universities, such as the Australian National University, set a minimum ATAR of 85 for their Bachelor of International Relations. However, many institutions also accept alternative entry pathways, including diplomas, TAFE qualifications, mature-age entry, and completion of a university bridging program. There are no specific subject prerequisites for most programs, though a background in English, History, Politics, or a second language is considered advantageous. Postgraduate applicants (Master of International Relations or Master of Diplomacy) typically require a completed bachelor's degree in a relevant discipline, along with a competitive academic record.

For international students, or domestic students completing their secondary schooling in a language other than English, English language proficiency tests are required. The standard requirement across most Australian universities is an IELTS Academic score of at least 6.5 overall, with no individual band below 6.0. Equivalent scores via TOEFL iBT (typically around 79–87), PTE Academic, or other accepted tests are also accepted. At the postgraduate level, some universities require a minimum GPA or credit average from prior undergraduate study, and relevant work or research experience may strengthen applications to competitive programs. Alternative pathways such as graduate access schemes, bridging programs, or commencing study through Open Universities Australia are available for those who do not meet standard entry requirements.
