Members of the Young, Deck and Grant families established the Queensland Kanaka Mission in 1886 and extended it to various centres along the Queensland coast. A Solomon Islands Branch of the Queensland Kanaka Mission was formed in 1904. It established a principal mission station at Onepusu on the west coast of Malaita in 1905 and changed its name to the South Sea Evangelical Mission in 1907. The Mission continued to operate in the Solomon Islands, and in New Guinea after World War II, till it was localised in the 1980s.
