 Despite having these units available, heavy Allied bombing of Japanese airfields around Wewak in August 1943 greatly reduced the number of aircraft available to the Japanese and limited their ability to apply airpower throughout the campaign.The Japanese force lacked for transport, engineer and logistical support and was hampered by a lack of cohesion due to its disparate command structure and poor infrastructure.In contrast, the Australian force had fought together in previous campaigns and was backed up by a formidable logistical support base that could deliver them a technological and industrial superiority that the Japanese were unable to match.
