Review of Model Defamation Provisions

Standing Council of Attorneys-General, Stage 2 Review of the Model Defamation Provisions (MDPs)

Part A (internet intermediary liability for third-party content)

Part A of the Stage 2 Review of the MDPs concerned internet intermediary liability in defamation for the publication of third-party content. New South Wales led the Part A work.

On 22 September 2023, the Standing Council of Attorneys-General approved by majority the final amendments for Part A, subject to some jurisdictions’ Cabinet processes where necessary. Jurisdictions in the majority (all jurisdictions except South Australia) agreed they will use best endeavours to enact the Part A amendments to the MDPs for commencement on 1 July 2024. The public communique for the meeting can be viewed here.

The amendments include:

  • Two conditional, statutory exemptions from defamation liability for a narrow group of internet intermediaries, including search engines in relation to organic search results
  • A new innocent dissemination defence for internet intermediaries, subject to a simple complaints process (Model B)
  • A new court power to make orders against non-party internet intermediaries to prevent access to defamatory matter online
  • A requirement that courts consider balancing factors when making preliminary discovery orders
  • Updates to the mandatory requirements for an offer to make amends for online publications
  • Additional electronic means by which documents may be given or served

The Part A amendments are available on the Australasian Parliamentary Counsel’s Committee website.

In addition to the Part A amendments to the MDPs, the Australian Government will prepare an exemption to state and territory defamation laws from section 235(1) of the Online Safety Act 2021 (Cth).

Part B (absolute privilege)

Part B of the Stage 2 Review of the MDPs was led by Victoria. It considered whether absolute privilege should be extended to cover reports of conduct such as sexual harassment and sexual assault to police and other complaints-handling bodies.

On 22 September 2023, the Standing Council of Attorneys-General approved the final reforms for Part B, subject to some jurisdictions’ Cabinet processes where necessary. The Part B amendments to the MDPs extend absolute privilege to matter published to police. The amendments are available on the Australasian Parliamentary Counsel’s Committee website. Guiding principles will be used by jurisdictions to determine whether to extend absolute privilege to matter published to a complaints-handling body for the purposes of the Part B reforms.

Further information on the Part B reforms can be found on the Engage Victoria website.

Stage 1 Review of the MDPs

The Model Defamation Amendment Provisions have commenced in New South Wales, Victoria, South Australia, Queensland, Tasmania and the Australian Capital Territory.

This followed the former Council of Attorneys-General (CAG) approving amendments to Australia's Model Defamation Provisions (MDPs) on 27 July 2020, marking the end of the Stage 1 Review of the MDPs.

On 31 March 2021, Attorneys-General agreed that New South Wales, South Australia, Victoria and all other jurisdictions that are able to do so will commence the Model Defamation Amendment Provisions 2020 on 1 July 2021, and remaining jurisdictions will commence those provisions as soon as possible thereafter.

The Model Defamation Amendment Provisions can be viewed on the Parliamentary Counsel Committee's website. Consolidated Model Defamation Provisions (as at 27 July 2020) including amendments in Model Defamation Amendment Provisions 2020 can be viewed here.

The amendments follow wide-ranging consultations with media companies, peak legal bodies, academics, digital platforms and lawyers who represent both plaintiffs and defendants. The CAG's Defamation Working Party considered more than 70 submissions (see below).

The amendments have reset defamation law by improving the balance between protecting individual reputations and freedom of expression, particularly in matters of public interest.

Key changes include:

  • Clarification of the operation of the cap on non-economic damages;
  • Introduction of a new public interest defence modelled on section 4 of the UK Defamation Act 2013;
  • Introduction of a serious harm threshold for defamation claims, to be determined by the judicial officer as soon as practicable before the trial;
  • Introduction of a single publication rule which will enable the limitation period to run from the first publication of alleged defamatory material;
  • A requirement that concerns notices must be served with sufficient time for an offer to make amends to be made before proceedings can be commenced;
  • Introduction of a new defence for peer reviewed matters published in academic or scientific journals.
CAG also agreed to progress a second stage reform process focusing on the responsibilities and liability of digital platforms for defamatory content published online, as well as other issues Attorneys-General ask the DWP to consider.

Background to the Model Defamation Provisions reforms

The Model Defamation Provisions were endorsed in 2005 and each state and territory enacted legislation to implement the provisions. While responsibility for defamation law falls to individual states and territories, a national approach to reform is essential.

Led by the NSW Department of Communities and Justice, the Defamation Working Party invited feedback on draft amendments to the Model Defamation Provisions [PDF, 234kb] (PDF, 233.8 KB) (PDF, 233.8 KB) (PDF, 233.8 KB) (PDF, 233.8 KB). An unofficial consolidation [PDF, 441kb] (PDF, 444.1 KB) (PDF, 444.1 KB) (PDF, 444.1 KB) (PDF, 444.1 KB) was also prepared to assist review, which tracks the draft amendments to the existing Model Defamation Provisions.
