Operation SEMUT was a series of reconnaissance operations carried out by Australia's Z Special Unit during World War II as part of the Borneo Campaign. Operation GIRAFFE 3, connected with the reconnaissance operations of SEMUT East of Borneo, was a party of nine deployed via HMAS Blacksnake, commanded by Sub-Lieut John Key. On the 26th April 1945 they anchored off the West coast of Maloe Island in the Celebes. Using Hoehn military folboats (collapsible canoes), the party of four, including Key, landed at Pasirpoeth to gain information from the natives and repair their boats, which were used in reconnaissance work. The GIRAFFE 3 team then sailed on to nearby Tifore Island to give assistance and medical attention to natives. On the 30th April 1945, Blacksnake returned to Morotai.
