Over a period of 40 years, from the mid-19th century to the early 20th century, labor for the sugar-cane fields of Queensland, Australia included an element of coercive recruitment and indentured servitude of the 62,000 South Sea Islanders. The workers came mainly from Melanesia – mainly from the Solomon Islands and Vanuatu – with a small number from Polynesian and Micronesian areas such as Samoa, the Gilbert Islands (subsequently known as Kiribati) and the Ellice Islands (subsequently known as Tuvalu). They became collectively known as "Kanakas".
