 This was achieved by amalgamating the 2nd and 3rd Battalions of the 24th Infantry Regiment, and subsuming part of the 29th Light Horse Regiment to form a single battalion, The 24th Battalion was raised in Victoria with its headquarters in Surrey Hills, with detachments spread out around the area including depots at Camberwell, Box Hill, Upper Hawthorn, Ringwood and Belgrave.In 1927, territorial designations were adopted by the Citizens Forces and the battalion became known as the 24th Battalion (Kooyong Regiment); the battalion's motto – "I Hold Fast" – was also approved at this time.Initially, the battalion was manned through a mixture of voluntary and compulsory service; however, in 1929 the Scullin Labor government abolished the compulsory service scheme and replaced it with the all-volunteer Militia.
