Graduate Research applications may only be submitted once you have obtained an invitation to apply from the Faculty that offers the degree in which you wish to enrol. Different Faculties have different processes, so it is important that you read and follow the information that each Faculty provides.
This will depend on the expectations of the discipline. At a minimum a three page proposal with a research question, methodological approach and the citing of some key researchers should be undertaken. Refer to the learning support page.
