Criminal Procedure Act 1986

If during any criminal proceedings an accused person is given sensitive evidence, or a copy of sensitive evidence, by the prosecuting authority in the proceedings, the court must, on application by the prosecuting authority, direct the accused person to return the sensitive evidence or copy to the custody of the prosecuting authority at or before the end of each day during which the proceedings are heard.

At the completion of any criminal proceedings in which sensitive evidence is tendered by the prosecuting authority, or sensitive evidence given to the accused person by the prosecuting authority is tendered by the accused person, the court must, on application by the prosecuting authority, direct that the sensitive evidence, and any copies of the sensitive evidence made for the purposes of the proceedings, be returned to the custody of the prosecuting authority.
