The campaign also served to highlight the strengths and weaknesses of the individual soldiers and the lower level commanders. Following this and the fighting that followed at Buna–Gona, the American and Australian armies would take steps to improve individual and unit training and medical and logistic infrastructure would also be greatly improved, with an increased focus upon air transport to solve the supply problem. Within the Australian Army, there was a major restructure with the formation of Jungle divisions which addressed manpower issues and were more suited to operations in jungle environments. There was a significant reduction in the scale of motor transport, and Jeeps, with greater cross-country mobility, were employed rather than trucks. At battalion level, changes included increasing the number of mortars to eight, the addition of a machine gun platoon with four Vickers guns to enhance organic fire support, and a removal of the carrier platoon. The Land Warfare Centre, as it is now known, was established at Canungra, Queensland, with an emphasis on training for jungle warfare. Adrian Threlfall, in his thesis and subsequent book explores the challenges faced and how these shaped the Australian Army as a jungle warfare force.
