The first Malay people who came to Cocos Island were Banjar people from South Borneo (now part of Indonesia) who brought by Alexandar Hare, resident of Banjarmasin, at 1826. In 1827, John Clunies-Ross established coconut farm in Cocos Island. He need more worker, so recruited a number of workers who came from few ethnics in Nusantara, including Java, Bali, Sumatran people,etc. Some source said he got those workers in Batavia (now Jakarta) which was 'international city' where people from various ethnics lived there for business and seek a job. They joined Banjar people community who came earlier.
There was few waves of recruitment which John Clunies-Ross recruited worker from other places too, including Malacca and Penang (Malaysia).
Actually not all of Cocos Malay are Malay, but there were few Papua Melanesian too from Eastern Nusantara archipelago (now Eastern Indonesia). Notice the dark skinned man in 1:12, he is Papuan.
Why did Cocos migrated to Sabah?. In 20th century Cocos Malays started to thinking to leave the island to seek new life. Some of them migrated to Australia (mainland) and establish few Cocos communities there. But there were Cocos people who wanted to migrate to Malay region. They told about it to British colonial authority that then gave them an empty area in Sabah. So they migrated to Sabah in early of 1950's.
