Aitape can be reached by logging road from Vanimo and Wewak. Boats also leave Aitape Harbor to Vanimo and Wewak. There are two airstrips: Tadji, where most flights land, and Aitape. Tadji airstrip is located 10 km east of town.
History
First contact between the Aitape area and the outside world is believed to have occurred during the 15th century when large sailing expeditions arrived from China. It is certain that Malay fishing fleets were active along the Sepik coastline from the early 17th century when island inhabitants were recruited as navigators for these Malay fishing vessels. The first Christian missionary arrived in the Aitape area in 1896. It was Societatis Verbi Divini from Germany and Holland. The first mission station was established on the island of Tumleo in 1896. A second station was set up at Pro on the mainland the following year. The inhabitants of Pro requested that the mission station be established to protect them from raids by much larger settlements. The major native settlements at the time were at Sissano, Malol, and Arop. The island settlements of Tumleo, Ali and Seleo made up the next group of main settlements. Both the Siau and Bakla would band together annually for major trading expeditions taking in the Aitape coastline to the south east areas around Wewak. German authorities found it difficult to colonize the Siau and Bakla of the Aitape area. The Aitape area was officially described as uncontrolled during the German colonial period. Still, the Germans built a solid prison at Aitape and installed a powerful radio station which maintained quality communication with Europe. In 1908, the Aitape coastline was struck by a major tsunami event resulting in the collapse of an area of coastline between Arop and Sissano creating the Sissano Lagoon. By 1914 there were 68 missionaries and 6 new stations established along the coast. The town along with the rest of German New Guinea passed to Australian control after the First World War and became part of the Territory of New Guinea.
During the Second World War the town was occupied, along with the rest of the Territory of New Guinea, by the Imperial Japanese Army. During the recapture American forces bypassed the Japanese 18th Army based at Wewak, taking Aitape on 22 April 1944. A base was developed here and repulsed a major Japanese counter-attack. The Americans were content to hold Aitape and not advance far towards Wewak. In fact, Aitape was captured as part of a 3-pronged invasion by the Allies. There was little or no strategic gain to be had in doing so as the Japanese force based at Wewak no longer posed a real threat – cut off, short of supplies, and weakened from battle and diseases. In mid-1944, General Douglas MacArthur, the American Commander-in-Chief of Allied forces in the South-West Pacific Area, secured an agreement from the Australian government for Australian forces to take over at Aitape. MacArthur then continued island hopping in preparation for the re-capture of the Philippines. The Aitape-Wewak campaign was the final Australian military campaign on mainland New Guinea. It ran from November 1944 to the war's end in August 1945. It was fought by the 6th Division, Australian Imperial Force with air and naval support. Australian intelligence soldier Leonard Siffleet was beheaded by Japanese on Aitape beach 24 October 1943 .
Tsunami
In July 1998, the area surrounding the town suffered from a destructive tsunami that killed over 2,000 people. A magnitude 7.0 earthquake occurred offshore and triggered a large undersea landslide that generated the tsunami. The area worst hit was Warapu village about 8 km west of Aitape. The village was situated on a narrow spit between the coast and a large lagoon. It is estimated that waves with an average height of 10.5 metres passed over the spit into the lagoon.
