Witness Protection Act 1996

If, in any proceeding in a court, a tribunal or a royal commission or board of inquiry, the identity of a participant is in issue or may be disclosed, the court, tribunal, commission or inquiry must, unless it considers that the interests of justice require otherwise—

hold that part of the proceeding that relates to the identity of the participant in private; and

make the order relating to the suppression of publication of evidence given before the court, tribunal, commission or inquiry that, in its opinion, will ensure that the identity of the participant is not disclosed.

If in any proceeding in a court, a tribunal or a royal commission or board of inquiry, a participant who has been provided with a new identity under the witness protection program is giving evidence, the court, tribunal, commission or inquiry may hold that part of the proceeding in the absence of the public.
