DEFAMATION ACT 2005 – SECT 27
Defence of absolute privilege
(1) It is a defence to the publication of defamatory matter if the defendant proves that it was published on an occasion of absolute privilege.
(2) Without limiting subsection (1), matter is published on an occasion of absolute privilege if–
(b) the matter is published in the course of the proceedings of an Australian court or Australian tribunal, including (but not limited to)–
(i) the publication of matter in any document filed or lodged with, or otherwise submitted to, the court or tribunal (including any originating process), and
(ii) the publication of matter while giving evidence before the court or tribunal, and
(iii) the publication of matter in any judgment, order or other determination of the court or tribunal, or
(d) the matter is published by a person or body in any circumstances specified in Schedule 1.
