The student union organises the annual Prosh week events inspired by the medieval tradition of ragging or "an extensive display of noisy disorderly conduct, carried on in defiance of authority or discipline".
[1][2] The annual Procesh procession began in 1905 as a means for students to poke fun at established South Australian institutions, though ragging at the university dates back to the late 19th century.
[1][2] In one example, multiple alarm clocks set and hid by students behind books made constant interruptions during a 1896 ceremony at the former Mitchell Building library.
[1][3] Among notable pranks, students suspended a car on Adelaide University Footbridge in 1974 above the River Torrens as part of Operation Bridge-hang.
[1][2] Following the end of free university education, the event has toned down in more recent times as a result of increased work commitments by students and the rise of social media for activism.
