His office sent us the following convoluted public servant jargon about privacy, without answering our question.

There are existing privacy safeguards in place under the Privacy Act 1988 and the confidentiality rules in the Social Security (Administration) Act 1999. These laws provide that protected information, including any personal information such as health information, can only be accessed, used or disclosed in limited circumstances. Under the social security law, this includes for the purposes of administering that law; for research, statistical analysis or policy development; and where it has been certified as being in the public interest. These existing safeguards will apply to any information gathered as part of this trial.

A comprehensive Privacy Impact Assessment will be undertaken in conjunction with the Office of the Australian Information Commissioner as part of the implementation of the trial to ensure the protection of privacy in accordance with the Australian Privacy Principles.
