Catholic Diocese of the Australian Military Services

The Catholic bishop is the head of the Catholic denomination recognised in the Defence Instructions (General) of the ADF.

The following individuals have been elected as Bishop of the Armed Services:[1]

Army and Air Force have three Principal Chaplains; one each to represent Catholicism, Anglicanism and nonconformist Protestantism. In January 2018, the Australian Navy removed the requirement to have three Principal Chaplains. They are accorded the rank relevant to the Division Five chaplain for each branch (1 star rank or O7). Principal Chaplains (who in the Catholic Military Diocese are also Episcopal Vicars, and currently are also Monsignors) oversee the chaplains of their particular Service, managing matters such as recruitment, postings, deployments, promotions, welfare and discipline.

Catholic priests who are promoted to Principal Chaplains of the ADF are traditionally nominated for and receive the title monsignor from the Pope. The current Catholic Principal Chaplains of the ADF are: Air Force - Monsignor (Air Commodore) Peter O'Keefe AM VG EV (also Vicar General of the Military Ordinariate); Navy - Monsignor (Commodore) Stuart Hall, RAN (also full-time Parish Priest in Malvern East Victoria); Army - Monsignor (Brigadier) Glynn Murphy OAM (also full-time Parish Priest Horsham Victoria). Currently all Catholic Principal Chaplains are in the Reserve Forces.

Chaplains are charged with the responsibility to care for the religious, spiritual and pastoral (welfare) needs of Defence members and their families. For Catholic chaplains, this includes providing the sacraments, especially to Defence members isolated from civilian Catholic churches/parishes or on war operations. Chaplains, especially those appointed to training establishments, conduct classes on ethics, morals, values and character development with their military units. Chaplains in the Navy, Army and Air Force undergo the same training as other ADF officers.

With only a few exceptions, ordained Catholic chaplains (priests and deacons) are "on loan" to the Military Diocese from a "civilian" diocese for an agreed period of time, which may or may not be renewed. The Bishop of the Military relies on the other Australian bishops for the supply of enough clergy to meet the chaplaincy needs of Catholics in the ADF. It is possible for a priest or deacon to be ordained solely into (incardinated) the Defence Diocese/Military Ordinariate and thus he fully belongs to the Military Diocese for life.

ADF chaplains are generally addressed by their first name by Officers of equal or superior rank or as "Sir" by those of lower ranks, however Catholic chaplains are often referred to as "Father" or as "Padre" by soldiers, sailors, and RAAF personnel irrespective of their rank.

Chaplains in the ADF are organised into five divisions:

^(1) Australian Navy Chaplains do not wear any rank insignia (instead wearing a cross and anchor emblem copied from the British Royal Navy), but under Defence Instructions - Navy, they are accorded a status equivalent to the rank listed in the table. Although differentiated by Division, Navy Chaplains in Divisions 1 to 3 are all given the status of a Commander (OF-4/O5).
