Modern Australian Republicanism is predicated on the supremacy of the individual, and the government deriving their legitimacy to make laws from the consent of the people. The basis for this consent is void when individual rights are violated by the government. Rights exist for all individuals under the jurisdiction of the government's ability to make and execute laws - a right is not unique to a citizen, nor an individual from a majority - they are universal to all.

Torture is a vehicle of state oppression and intimidation. It has no place in an Australian Republic. (more)
