The States were careful to include provision that the complex interrelationship between the Sovereign, the Commonwealth and the states was not affected by the Act, as unlike the Canadian provinces, Australian states have relationships with the Crown which are independent of the Commonwealth. For example, a Canadian lieutenant governor is appointed by the Governor General of Canada on the advice of the prime minister and subject to their authority, whereas the governors of the Australian states are appointed by the Sovereign on the direct advice of the premier of the state in question, and are not subject to the authority of the Governor-General. The governors hold a dormant commission to assume the position of Administrator of the Commonwealth should the Governor-General die, resign or be absent from Australia. A dormant commission can be revoked by the Commonwealth, such as when the dormant commission of Sir Colin Hannah, Governor of Queensland, was revoked for making partisan political comments shortly before the 1975 constitutional crisis.
