Macquarie scholarships can apply across many subjects, and eligibility can vary by your field of study (as well as your country and achievements). You’ll commonly see scholarship eligibility for broad areas like business, engineering, STEM (including IT/data-related fields), and humanities/social sciences, depending on the scholarship rules. From a real recipient example, Anupam Sarkar studied accounting (business-related) and noted he received a scholarship “awarded to the top 1% of international students.”
Medicine: Macquarie does offer an international pathway into medicine via a combined Bachelor of Clinical Science/Doctor of Medicine (Macquarie MD) package for international high school graduates. However, not every scholarship applies to clinical/medicine degrees. Some large international scholarships explicitly exclude degrees such as Bachelor of Clinical Science and Doctor of Medicine, so medicine applicants should double-check scholarship exclusions.
