On Dit is a student newspaper funded by the Adelaide University Union and advertising revenue which is published fortnightly during semester time. Founded in 1932, it is the third oldest student newspaper in Australia along with Semper Floreat (which was first published in the same year as On Dit). The paper replaced its precursor the Varsity Ragge which ran from 1928 to 1931 when it ended because of what On Dit described in its first edition as 'student apathy'. The Varsity Ragge returned in 1934 for a single edition as a rival to On Dit.
