31st/42nd Battalion, Royal Queensland Regiment
31st/42nd Battalion, Royal Queensland Regiment (31/42 RQR), was officially formed in January 2008 by the amalgamation of 31st Battalion, Royal Queensland Regiment, and 42nd Battalion, Royal Queensland Regiment.
However, the unit has a long history and can trace its lineage back to units formed in 1881 as part of the colonial defence forces of the state of Queensland.
These units were mainly used in home defence duties, although during the Second Boer War and World War I many of their members volunteered for overseas service and, by virtue of this service, battle honours from these wars were bestowed upon these units.
During World War II, both of these units were called upon to play an active role in the fighting in the Pacific, thus earning more battle honours.
After World War II, these units were disbanded and then reformed as part of the Citizens Military Force in 1948, which was a forerunner to the current Army Reserve. As a part of that organisation, both 31st Battalion and 42nd Battalion continued to exist in various forms for the next 60 years before it was decided to amalgamate the two units early in 2008.
Currently, 31/42 RQR has depots located along the Queensland coast from Gladstone to Cairns. In February 2009, 31/42 RQR returned from a successful deployment as part of Rifle Company Butterworth Rotation 84.
The motto of the Royal Queensland Regiment is 'Pro Aris Et Focis', which is Latin for ‘For Alters and Hearths’.
