The Australian Baptist Missionary Society came to Papua New Guinea as a member of the Evangelical Alliance which commenced educational work in the Territories in the 1950s. The 1980 census recorded 2.3 percent of the Christian population as Baptists. Baptists did not appear as a separate denomination in the 1990 census. However, in 1993 the Baptist Union, the largest of several Baptist groups, was a member of the Papua New Guinea Council of Churches. Other Baptist groups were members of the Evangelical Alliance.
