The 25th/49th Battalion, Royal Queensland Regiment (25/49 RQR) is a Reserve light infantry battalion in the Australian Army, based in the state of Queensland. Although it was officially formed in 1997, the unit can trace its lineage back to units that were formed in 1875 as part of the colonial defence force of the state of Queensland. Additionally, in order to preserve the honours and traditions of the Australian Imperial Force, the battalion is the custodian of the battle honours awarded to two battalions that were formed for service during World War I. Following the end of the war, these units were raised again as militia units. During World War II, these battalions were called upon to participate in the fighting in the Pacific. Following the end of the war, these units were disbanded although they were later re-raised as part of the Citizen Military Forces, which was the forerunner to the Australian Army Reserve that exists today.
In 1960, the Pentropic division was introduced into the Australian Army and many of the old CMF units were disbanded or subsumed into the newly raised state-based regiments. As a result, the previously existing 25th Battalion became part of the 1st Battalion, Royal Queensland Regiment while the 49th Battalion became a special conditions unit responsible for training national servicemen who were unable to meet their training obligations due to their location. In 1965, however, the Pentropic division was discontinued and it was decided to reintroduce the regional numerical designations of many of the CMF battalions. In 1997, with the cessation of the Ready Reserve scheme the 25th and 49th Battalions were amalgamated to form the 25th/49th Battalion, Royal Queensland Regiment.
Up until 2007 the battalion was part of the 7th Brigade, headquartered at Enoggera Barracks in Brisbane; however, on 8 July 2007 the battalion was transferred to the 11th Brigade. It currently contains a mix of Reserve and Regular Army soldiers and has companies based across Southeast Queensland. In 2006, the Battalion provided the nucleus of a composite company of Reserve soldiers that deployed to the Solomon Islands as part of the United Nations Regional Assistance Mission. Individual members of the unit have also deployed to East Timor, Iraq and Afghanistan as part of the round-out and reinforcement program with the Regular Army.
