Sideia Island was sighted by Europeans when the Spanish expedition of Luís Vaez de Torres arrived on 18 July 1606.[3] Their ship, San Pedro anchored at Oba Bay in the south west, that they then named Puerto San Francisco. It was later renamed as Puerto Lerma after the 1st Duke of Lerma. Torres named the island St. Bonaventure.
The mission in that island was established on April 22, 1932 by the Australian Province of the French Congregation Missionaries of the Sacred Heart (MSC). By 1942, it was fully developed and became the base for other missions in the nearby islands. Many facilities were set up to provide education, medical assistance and ways of living to the native of the area.[4]
