Criminal Code Act 1983

Any person who in any judicial proceedings, or for the purpose of instituting any judicial proceedings, knowingly gives false testimony touching any matter that is material to any question then depending in the proceedings, or intended to be raised in the proceedings, is guilty of an offence that is called perjury.

It is immaterial whether the testimony is given on oath or under any other sanction authorized by law.

The forms and ceremonies used in administering the oath or in otherwise binding the person giving the testimony to speak the truth are immaterial if he assents to the forms and ceremonies actually used.

It is immaterial whether the false testimony is given orally or in writing.

It is immaterial whether the court or tribunal is properly constituted, or is held in the proper place or not, if it actually acts as a court or tribunal in the proceedings in which the testimony is given.

It is immaterial whether the person who gives the testimony is a competent witness or not, or whether the testimony is admissible in the proceedings or not.
