The first entry into mainland Australia by Torres Strait Islanders from the Torres Strait began in about the 1940s. Prior to that pre-colonisation the Indigenous peoples of the Torres visited Keo Daudai(mainland Australia)based on reciprocal trade relations in their double outrigger canoes. There are records of their journey for up to 800km from the Torres Strait. During the late 1800s Torres Strait Islanders came under the Aboriginal Protection Act which restricted their movements and confined them to the Torres Strait. The home of Torres Strait Islanders became their prison. Torres Strait Islanders lived in missions run by the LMS.
