patrols throughout the northern sector, before being relieved for a rest out of the line. This rest did not last very long, however, as a company from the 31st/51st were called upon to carry out an amphibious landing at Porton, as the rest of the battalion advanced further north from the line that had been set up at Ratsua–Ruri. The landing occurred on 7 June, however, the company was quickly surrounded by the Japanese and as the rest of the battalion attempted to break through to them, they were evacuated by sea. This brief second campaign on Bougainville lasted until 28 June when the 11th Brigade was relieved by the 23rd Brigade. During this time the 31st/51st had suffered 100 casualties, consisting of seven missing, 14 killed and 79 wounded. The battalion took no further part in the fighting and after the Japanese surrender the battalion was moved to Nauru and Ocean Island to carry out garrison duties where they remained until December 1945 when they were transferred to Rabaul on New Britain. They remained there as an occupation force until May 1946 when the unit returned to Australia, where the 31st/51st Battalion (Kennedy and Far North Queensland Regiment) was disbanded on 4 July 1946. For their involvement during World War II, members of the 31st/51st Battalion received 43 decorations, including: one Distinguished Service Order, one Distinguished Conduct Medal, three Military Crosses, ten Military Medals, one British Empire Medal and 27 Mentions in Despatches. Post World War II After World War II the militia units were re-formed as part of the Citizens Military Force (CMF) and subsequently the battalion was re-raised in 1948, this time as the 31st Battalion, North Queensland Regiment. John Peel was approved as the battalion's regimental march in 1953. In 1960, the battalion's designation was changed again when it was decided to introduce the Pentropic organisation into the Australian Army, a part of which required the reorganisation of the regionally based CMF battalions into six State based regiments. As a result of this the battalion became the 2nd Battalion, Royal Queensland Regiment. The battalion received its World War II battle honours in 1961, and was entrusted with those earned by the 2/31st Battalion at the same time. In 1965, the Australian Army moved away from the Pentropic organisation and returned to the previous establishment and it was decided to return to the CMF battalions to their
