 The Protection of Aboriginals and Restriction of the Sale of Opium Amendment Act 1934 extended the provisions of the 1897 Act and the powers of the Chief Protector.It enabled compulsory medical examinations, and also allowed for "uncontrollable" Aboriginal people or "half-castes" (the definition of this term was changed to include South Sea Islander people) to be sent to an institution.The latter enabled the incarceration of people at the Fantome Island lock hospital for non-medical reasons.
