Adjacent to the accommodation blocks is the Academy Cadets Mess, which is the largest Officers Mess in Australia. The Cadets Mess is designed to seat 1000 people and cater for up to 1200 officer cadets and midshipmen.
The Cadets Mess comprises food preparation areas, kitchens, dining areas, bars, recreation rooms and a shop. Recreation areas include pool tables, a TV entertainment area and lounges. While attending ADFA, cadets and midshipmen are generally offered three cooked meals a day in the Mess, with several options each meal. Vegetarian, halal and low fat options are also provided.
Division Staff organise a number of social activities for cadets during the year, which may be catered by the Cadets Mess through barbeque packs which can be cooked in the accommodation precinct or at nearby Lake Burley Griffin.
Staff at ADFA have access to a separate Officers Mess and Sergeants Mess located on site, but will often join officer cadets and midshipmen for meals during the year.
