 Each province was governed by an Administrator, appointed by the central government, and had a legislature in the form of a unicameral Provincial Council; four members of the Council joined with the Administrator to form a five-member executive committee that acted as the Province's Cabinet.Unlike Canada and Australia, which became dominions through the Federation of British colonies, the South Africa Act created a centralized, unitary state.Each of the four provinces became subordinate entities and had far fewer powers than the Canadian provinces or Australian states.
