[6] In 1989 the Trinity College Foundation Studies program was established to prepare international students for entry to the University of Melbourne.

Situated to the north of the main University of Melbourne campus, as part of College Crescent, Trinity's buildings surround a large grassed area, known as the Bulpadock.

Trinity College participates in many different sports in intercollegiate competition, including Australian rules football, soccer, netball, hockey, athletics, swimming, volleyball, squash, tennis and badminton.

The current college song was written by the fifth warden, Evan Burge (1974–1996), set to the hymn tune "Thaxted" derived from the "Jupiter" movement from Gustav Holst's The Planets.

The Choir of Trinity College has become known, especially but not exclusively, for choral music in the tradition of English cathedrals and the collegiate chapels of Oxford and Cambridge universities.

The choir also performs locally and tours internationally and have made a number of radio broadcasts and CD recordings, including five albums for ABC Classics.

Leadership of theological education at Trinity was originally the responsibility of the college chaplains under the supervision of the warden.

Many alumni served during the world wars; however, unless they pursued a military career or were killed in action it is their later achievements in the field of endeavour in which they are listed.
