The organisation was founded in 1886 as the "Queensland Kanaka Mission" (QKM) in Queensland, Australia, as an evangelical and non-denominational church targeting Kanakas (blackbirded
labourers at the sugarcane plantations, mostly from Solomon Islands and Vanuatu).
Florence Young, the sister of Arthur, Horace and Ernest Young, the owners of the Fairymead plantation on which the mission was located, was largely responsible for the establishment of the mission, and served as secretary of the organisation. At its height in 1904–05, it employed 19 missionaries, 118 unpaid "native teachers," and celebrated 2150 conversions. Young used pidgin English and illustrations to explain the resurrection and other Christian ideas.
The South Seas Evangelical Mission (SSEM) was established in 1904 by Young as a branch of the Queensland Kanaka Mission. Its purpose was to follow the workers back to their homeland, and maintain their religious instruction there. At that time fewer workers were coming, due to the White Australia policy.
