Native Administration Act 1905

The Native Administration Act, originally titled the Aborigines Act, and later renamed to the Native Welfare Act; was a legislative act of the Western Australian legislature. Alongside the Aborigines Protection Act (1905), the act enabled the surveillance and control of Aboriginal people by agents of the colonial state government in the early 20th century.

The act sought to regulate Aboriginal people "more than any other legislation in Western Australia". It was formerly named the Aborigines Act on its original passage in 1905, and remained in its original form until substantial amendments in 1936. Both forms of the act were passed by the WA Labor governments.
