The Privacy Act is administered by which of the following bodies?

The Privacy Act is administered by the Office of the Australian Information Commissioner. This body is responsible for overseeing compliance with the Privacy Act, which includes ensuring that organizations adhere to privacy principles regarding the handling of personal information. The Commissioner plays a vital role in promoting and protecting the privacy rights of individuals, providing guidance to organizations, and handling complaints related to breaches of privacy.

The other choices do not have a role in administering the Privacy Act. The Department of Justice primarily deals with legal enforcement and policy-making but is not specifically responsible for privacy issues. The Australian Competition and Consumer Commission focuses on consumer protection and competition, while Parliament of Australia is responsible for legislation and policy-making rather than enforcement of privacy laws specifically. Therefore, the Office of the Australian Information Commissioner is the correct body responsible for administering the Privacy Act.
