Experience in New Guinea in 1942, particularly around Buna–Gona demonstrated that, like almost all vehicles, the Universal Carrier was ill-suited to the dense jungle terrain common throughout the south-west Pacific. As a result, when the Australian Army restructured its six front-line infantry divisions as Jungle Divisions in 1943 the infantry battalion carrier platoons were disbanded and replaced by a single divisional carrier company. The divisions which were retained on the British-pattern organisation retained their battalion carrier platoons. Due to the Universal Carrier's vulnerability in jungle terrain the divisional carrier companies were mainly used to transport supplies to forward positions and to provide defence for the division's rear areas, although there were some examples of them being used for patrol work in New Guinea. For example, in April 1944, after being ferried into position by several aircraft, a platoon from the 11th Division's carrier company clashed with an isolated group of Japanese around Wantoat during the advance towards Madang.
