The Defence International Training Centre (DITC) is an Australian Defence Force training unit, located at RAAF Williams, 20 km from the centre of Melbourne. DITC is a modern complex consisting of classrooms, library, language laboratory, computer laboratory and television and sound studio, as well as a large and well equipped student common room open to students 24 hours a day. Students are accommodated in comfortable single rooms in four-room units that are adjacent to, but detached from, the main buildings. Each unit has its own common room, television and video, as well as laundry and toilet facilities. Some accommodation units are also equipped with computers for student use.

Meals for students are provided in the RAAF Williams Officers, Sergeants and Airmens messes. All messes provide Australian and Asian food, as well as meals to meet the special requirements of the many cultural and religious groups attending DITC.

After hours, students can relax at the base cinema, work out in the gymnasium, enjoy a round of golf, play squash or tennis, or go for a swim in the pool. Sporting equipment is provided for students.

Just outside the base there are several shops and a supermarket, as well as a railway station where trains depart regularly for Melbourne; a journey of about 35 minutes.

Most students at DITC come from the defence forces of more than 30 Asian, Middle Eastern, South East Asian and South West Pacific nations. They range in rank from newly enlisted personnel to senior officers. Scientists, engineers and other ranks also attend DITC courses from time to time. Over 800 students a year pass through DITC, with an average of fifty students in residence at any one time.

The Defence International Training Centre (DITC) was originally established in 1979 when the Army Languages Training Wing amalgamated with the RAAF School of Languages. The Centre became Detachment A. In 1982 it was retitled the RAAF Defence Co-operation Language School, and became a tri-Service unit in 1985 when it was renamed the Defence Co-operation Language School. Another name change occurred in 1990 when the unit adopted its current title. Joint Directive 3/94 signed on 30 November 1994 by the Chief of the Defence Force (Admiral Beaumont) and the Secretary (Ayres) formally established the unit in its current form.
