Chaplains have been associated with the military for centuries and were often referred to in historical records of famous battles.

The chaplain always had a dual role - rendering spiritual support to the king and his court, and to the soldiers who went into battle.

In Australia, the first chaplains were appointed to the Australian Military Forces in 1913.

On 24 October 1786, the Reverend Richard Johnstone was appointed by George 111 to accompany the fleet to serve as Colonial Chaplain.

The first informal provision of police chaplaincy in the United Kingdom occurred in 1842 when the London City Mission offered pastoral support to widows of serving police officers. This was formalised in 1851.

In NSW, the Guild of St Christopher was founded in 1933. They provided support and fellowship for Catholic police officers decades before a formal arrangement was put in place. The Chaplain to the Guild was part of the ministry belonging to St Mary's Cathedral.
