The Papuan campaign led to a significant reform in the composition of the Australian Army. During the campaign, the restriction banning CMF personnel from serving outside of Australian territory hampered military planning and caused tensions between the AIF and CMF. In late 1942 and early 1943, Curtin overcame opposition within the Labor Party to extending the geographic boundaries in which conscripts could serve to include most of the South West Pacific and the necessary legislation was passed in January 1943. The 11th Brigade was the only CMF formation to serve outside of Australian territory, however, when it formed part of Merauke Force in the NEI during 1943 and 1944.
