 In 1948 , with demobilisation of Australia 's wartime army complete , the decision was made to re @-@ raise the part @-@ time forces of the Militia , albeit with the new name of the Citizens Military Force , on a reduced establishment . The 27th Battalion was re @-@ raised in May 1948 , and was once again assigned to the 3rd Division , attached to the 9th Brigade . In 1951 , the compulsory training scheme was reintroduced and as a result the size of many CMF units swelled . The march , The Campbells Are Coming , was approved as the battalion 's regimental march in 1953 . In 1959 , the national service scheme was suspended , and as a result numbers dropped once more . Following the introduction of the Pentropic divisional structure in early 1960 , the CMF was reorganised and a number of infantry battalions were disbanded or amalgamated together to form six new State @-@ based regiments .
