At this time three structures (a drill hall, wagon shed and earth closet) were removed from Mount Morgan and re-erected at the training depot. The drill hall and wagon shed, although modified, have remained on the property since that time. Plans to renovate the 1906 drill hall were carried out in 1937, when it was extended on the southern side. By 1943, the original armoury had been replaced with an ablutions and store block. A petrol/oil store was located to the west of the drill hall. This was later removed and a brick store was constructed in the north-west corner. The drill hall moved from Mt Morgan was being used for administration and also as a lecture hall, while the wagon shed moved from Mt Morgan was in use as a garage. By far the most construction taken place on the site was at the northern end. Buildings included another store, latrines, officers' mess and two buildings used as sleeping quarters, as well as an administration building, kitchen/officers' mess, other sleeping quarters and sergeants quarters. By 1943 the brick Q store had also been constructed. According to the oral histories from those who were associated with the site, the Q store had been constructed at least by 1939. A section of this building was also utilised as a magazine, until it was decommissioned in the 1980s. During the Second World War, army medicals were held in the 1906 drill hall, which, by then, was also used as a recruiting depot. Similarly, in the 1950s, medicals for National Servicemen were held in the hall. The adjacent parade ground was the assembly point for servicemen on route to camp. Following the war, the drill hall was a popular venue for functions and dances and the 42nd Battalion used to cater for refreshments as a fundraiser. By 1939, the rifle range has also been constructed. The range was used for firing 22 calibre bullets inside modified 303 and other rifles. This served the dual purpose of allowing reservists to have regular weapons handling practice and to provide experience prior to using larger calibre bullets at a regular, but less easily accessible, firing range. The range was used by school cadets from at least the Second World War. Besides defence units, the range was also used by civilian clubs, until the late 1980s. At various times sections of the 1906 drill hall have been used as a Q Store, armoury, sergeant's mess and secure storage for vehicles loaded with goods. Immediately before its decommissioning, the drill hall fulfilled a number of purposes for the 42nd Battalion, as offices for Battalion headquarters staff, officer's mess and hall.
