A folding kayak is a direct descendant of the original Inuit kayak made of animal skins stretched over frames made from wood and bones. A modern folder has a collapsible frame made of some combination of wood, aluminium and plastic, and a skin made of a tough fabric with a waterproof coating. Many have integral air chambers inside the hull, making them virtually unsinkable.
The Battle of Timor occurred in Portuguese Timor and Dutch Timor during the Second World War. Japanese forces invaded the island on 19 February 1942 and were resisted by a small, under-equipped force of Allied military personnel—known as Sparrow Force—predominantly from Australia, United Kingdom, and the Dutch East Indies. Following a brief but stout resistance, the Japanese succeeded in forcing the surrender of the bulk of the Allied force after three days of fighting, although several hundred Australian commandos continued to wage an unconventional raiding campaign. They were resupplied by aircraft and vessels, based mostly in Darwin, Australia, about 650 km (400 mi) to the southeast, across the Timor Sea. During the subsequent fighting, the Japanese suffered heavy casualties, but they were eventually able to contain the Australians.
Operation Jaywick was a special operation undertaken in World War II. In September 1943, 14 commandos and sailors from the Allied Z Special Unit raided Japanese shipping in Singapore Harbour, sinking six ships.
The Borneo campaign or Second Battle of Borneo was the last major Allied campaign in the South West Pacific Area during World War II to liberate Japanese-held British Borneo and Dutch Borneo. Designated collectively as Operation Oboe, a series of amphibious assaults between 1 May and 21 July 1945 were conducted by the Australian I Corps, under Lieutenant-General Leslie Morshead, against Imperial Japanese forces who had been occupying the island since late 1941 – early 1942. The main Japanese formation on the island was the Thirty-Seventh Army under Lieutenant-General Masao Baba, while the naval garrison was commanded by Vice-Admiral Michiaki Kamada. The Australian ground forces were supported by US and other Allied air and naval forces, with the US providing the bulk of the shipping and logistic support necessary to conduct the operation. The campaign was initially planned to involve six stages, but eventually landings were undertaken at four locations: Tarakan, Labuan, North Borneo and Balikpapan. Guerilla operations were also carried out by Dayak tribesmen and small numbers of Allied personnel in the interior of the island. While major combat operations were concluded by mid-July, localised fighting continued throughout Borneo until the end of the war in August. Initially intended to secure vital airfields and port facilities to support future operations, preparatory bombardment resulted in heavy damage to the island's infrastructure, including its oil production facilities. As a result, the strategic benefits the Allies gained from the campaign were negligible.
Z Special Unit was a joint Allied special forces unit formed during the Second World War to operate behind Japanese lines in South East Asia. Predominantly Australian, Z Special Unit was a specialist reconnaissance and sabotage unit that included British, Dutch, New Zealand, Timorese and Indonesian members, predominantly operating on Borneo and the islands of the former Dutch East Indies.
Operation Rimau was an attack on Japanese shipping in Singapore Harbour, carried out by an Allied commando unit Z Special Unit, during World War II using Australian built Hoehn military MKIII folboats. It was a follow-up to the successful Operation Jaywick which had taken place in September 1943, and was again led by Lieutenant Colonel Ivan Lyon of the Gordon Highlanders, an infantry regiment of the British Army.
The Snake-class junks were a class of six small vessels operated by the Royal Australian Navy (RAN) to support special forces operations in 1944 and 1945. The ships were lightly armed and were used to infiltrate special forces parties and their supplies into Japanese-held territory.
Operation Python was carried out by the Allied commando unit Z Special Unit, during World War II. The objective of the mission was to set up a wireless station near Labian Point in North Borneo and undertake covert operations reporting on the sea lane of the Imperial Japanese Navy in the Sibutu Passage and the Balabac Strait of the Sulu Sea. The operation was split into Python I and Python II.

Operation Copper was carried out by the Allied commando unit Z Special Unit, during World War II. The objective of the mission was to investigate the Japanese defences on Muschu Island, capture a Japanese officer for interrogation and discover the location of two naval guns on the island that covered the approaches to Wewak Harbour. Eight commandos were landed as part of the operation; only one survived.
Operation Semut was a series of reconnaissance operations carried out by Australia's Z Special Unit in 1945, during the final stages of World War II. This operation was the part of the Borneo Campaign, and was undertaken in Sarawak, northwestern Borneo, in support of Allied operations to secure North Borneo. Another closely related operation codenamed Agas was carried out concurrently in North Borneo. Both operations combined and relayed their intelligence through the Stallion Project to Australian forces and carried out guerrilla warfare against the Japanese in the region with the full support of the local population. A total of four operations were undertaken under the auspices of Operation Semut, concluding in September and October 1945.
