The Doctor of Philosophy (Design) is Australia's highest research qualification in the design discipline, situated within the Creative Arts field. It is a research-intensive degree in which candidates undertake an original, substantial inquiry into a focused area of design practice, theory, history, or methodology. The program encompasses a broad range of design specialisations — including graphic design, industrial design, interaction and UX design, spatial design, fashion design, service design, design thinking, and sustainable design — allowing candidates to shape the direction and scope of their own research under expert academic supervision. Rather than following a prescribed curriculum, doctoral candidates develop and execute an independent research project that makes a demonstrable and original contribution to design knowledge. This may take the form of a traditional thesis, a practice-led research project combining creative artefacts with written exegesis, or a thesis by publication, depending on the institution and the nature of the inquiry. The degree typically spans three to four years full-time (or up to six to eight years part-time) and is structured around supervisory milestones, confirmation of candidature, and final examination by independent assessors. Graduates emerge as expert researchers capable of applying rigorous analytical and creative methodologies to complex design challenges. Employers of PhD (Design) graduates span a wide spectrum: universities and research institutes, government innovation and policy agencies, large corporations with in-house design research divisions, cultural institutions such as museums and galleries, technology companies, design consultancies, NGOs, and independent practice. The qualification is valued both for the deep discipline expertise it confers and for the transferable high-order research, critical thinking, and communication skills it develops.

To be eligible for a Doctor of Philosophy (Design) at an Australian university, applicants typically require a bachelor's degree with at least upper second-class honours (2:1 or above) in design or a closely related discipline, or a master's degree — preferably one with a significant research component such as a thesis or research project. Many institutions specifically require first-class or upper second-class honours, with some guidelines indicating that the equivalent of an average grade between 70–100% in final-year study is expected. Applicants without an honours degree may be considered if they can demonstrate equivalent research experience through industry publications, technical reports, or professional practice. A key requirement across all Australian institutions is the submission of a detailed research proposal outlining the intended research question, methodology, significance, and scope, as well as securing agreement from an eligible academic supervisor prior to enrolment. In the case of design disciplines, applicants are often also required to submit a creative portfolio showcasing recent design work alongside critical written discussion that demonstrates scholarly engagement with their practice. Shortlisted applicants may be invited to attend an interview with a supervisory panel. International students must also satisfy English language proficiency requirements, typically an overall IELTS score of 6.5 with no band below 6.0, though some institutions require higher scores. Australian citizens, permanent residents, and New Zealand citizens may be eligible for tuition fee exemptions under the Australian Government's Research Training Program (RTP), which covers up to four years of full-time doctoral study. Scholarships offering living stipends are also competitively awarded to high-achieving domestic and international candidates.
