After 1940, use of the term "Militia" to describe the part-time military forces waned and by 1942 the term "Citizen Military Forces" (CMF) had become more common. Later in the war, the "Defence (Citizen Military Forces) Act 1943", officially referring to the organisation as the CMF, was passed to change the law to allow the transfer of Militia or CMF units to the AIF, if 65 percent or more of their personnel had volunteered for overseas service. Additionally, changes to the Act meant that Militia units were able to serve anywhere south of the Equator in the South West Pacific Area (SWPA), excluding western Java and northern Borneo, and as a result of this, Militia units saw action against Japanese forces in the Dutch East Indies, at Merauke, later in the war. Despite these changes, the AIF remained the Australian Army's main combat force during the war and indeed more than 200,000 members of the Militia transferred to the AIF throughout the course of the conflict. Nevertheless, 32 Militia infantry battalions, later organised into three Militia divisions (3rd, 5th and 11th), saw service over much of the South West Pacific and participated in the following campaigns: Salamaua-Lae, Huon Peninsula, Finisterre Range, New Britain and Bougainville.
