I’ve spent one semester in Adelaide on exchange from Italy.
The university is great from all points of view. Courses are well organised and schedule conflicts are easily solved. Professors and TAs are very competent, clear and always helpful, humble and available for any query. Labs and infrastructures are new and useful.
Students offices are well organised, efficient and proactive, organising lots of different activities for all students (especially international ones), and the student association is organising something nice every week as well.
The campus is great, located between the river and the city centre, with lots of green areas and places for students to relax or study, and the library is amazing.
