"How much will this cost?" is invariably the first question a prospective client asks. It is also the hardest to answer with precision, because defamation litigation is driven by variables that differ radically from case to case: the number of publications, the defences raised, the volume of evidence, and whether the matter settles early or proceeds to a contested trial.
What I can do — drawing on current fee scales, court filing fees, and the costs figures that have emerged in recent high-profile proceedings — is set out a realistic framework so that you can make an informed decision before committing to litigation.
The Short Answer
For a straightforward defamation matter resolved by a well-drafted concerns notice and negotiation, total costs might sit between $5,000 and $20,000. For a matter that proceeds through the interlocutory phase and settles at mediation, expect $30,000 to $80,000. A fully contested Supreme Court or Federal Court trial — with multiple witnesses, expert evidence and a hearing running several days — can easily exceed $150,000 to $500,000 per side, and in complex media cases the figures climb into the millions.
The Roberts-Smith litigation, for example, is estimated to have cost in the range of $13.5 million to $40 million across both parties over seven years of proceedings. The Reynolds v Higgins matter in Western Australia resulted in costs orders exceeding $1 million, on top of $315,000 in damages. These are extreme outliers, but they illustrate how quickly defamation litigation can escalate when neither party is prepared to resolve the dispute early.
Stage-by-Stage Cost Breakdown
1. Initial Consultation and Advice
Most defamation lawyers offer an initial consultation at either a fixed fee or on an hourly basis. In the current market, specialist defamation consultation fees typically range from $500 to $1,500 (including GST). Some firms charge $550 for a fixed-fee consultation; others bill at their standard hourly rate of $400 to $700 per hour for the first conference.

2. Concerns Notice
Under the uniform Defamation Act 2005 (and its state equivalents), a concerns notice is a mandatory prerequisite before commencing proceedings. The notice must identify the defamatory matter, specify the imputations, and explain why they are defamatory.
Preparing a properly particularised concerns notice — one that satisfies the statutory requirements while maximising settlement leverage — typically costs between $3,000 and $8,000. This includes reviewing the publications, formulating the imputations, and drafting a notice that is legally precise yet strategically effective.
If you are the publisher who has received a concerns notice, obtaining legal advice on your response — including whether to make an offer to make amends under sections 13–18 of the Act — will typically cost a similar amount.
3. Offer to Make Amends and Early Resolution
The Defamation Act creates a statutory incentive to resolve disputes without litigation. A publisher who receives a concerns notice has 28 days to make an offer to make amends, which must include an offer to publish a reasonable correction and to pay expenses reasonably incurred by the aggrieved person. The offer may also include an apology and payment of compensation.
If a matter resolves at this stage — through an accepted offer to make amends or negotiated settlement — total costs for both sides are typically $5,000 to $20,000. This represents the best possible costs outcome, and it is the reason we always advise clients to take the pre-litigation phase seriously.
4. Filing Proceedings and Interlocutory Applications
If pre-litigation efforts fail, the next step is filing a statement of claim. Court filing fees are not trivial:
- Federal Court: $1,735 for an individual; $5,050 for a corporation (from 1 July 2025)
- Supreme Court of Victoria: approximately $900 to $1,600 depending on the nature of the filing
- Setting down for hearing (Federal Court): $3,470 for an individual; $8,450 for a corporation
- Daily hearing fees (Federal Court): escalate from $1,375 per day (days 2–4) to $6,955 per day (day 15 onwards) for individuals
Solicitor costs for drafting the statement of claim, particulars of imputations, and any interlocutory applications (such as applications to strike out defences or for discovery) typically add $15,000 to $40,000 before trial.
5. Discovery and Evidence Gathering
Discovery — the process by which each party discloses relevant documents — is often the most labour-intensive phase of defamation litigation. In cases involving online defamation, this may include preliminary discovery applications to identify anonymous publishers, subpoenas to internet service providers, and forensic analysis of social media posts.
The costs of discovery alone can range from $10,000 to $50,000+, depending on the volume of documents and whether electronic discovery tools are required.
6. Mediation
Courts in Victoria and New South Wales strongly encourage — and in some cases mandate — mediation before trial. A mediator's fees for a full-day mediation typically range from $3,000 to $8,000 (split between the parties). Your solicitor's preparation and attendance will add another $5,000 to $15,000.
If a matter settles at mediation, total costs to that point are typically in the range of $40,000 to $80,000. While that figure may seem high, it is a fraction of what a contested trial would cost — and it provides certainty of outcome.
7. Trial
A defended defamation trial is expensive. The main cost drivers are:
- Barrister's fees: A junior counsel experienced in defamation will charge between $5,000 and $12,000 per day at trial, plus preparation fees (often a multiple of the daily rate). Senior counsel or King's Counsel can charge $15,000 to $30,000+ per day.
- Solicitor's fees: Your instructing solicitor will charge for trial preparation and attendance at rates of $400 to $700 per hour for a senior practitioner.
- Expert evidence: Where relevant — for example, damages quantification, forensic linguistics, or media impact analysis — expert fees add $5,000 to $20,000 per expert.
- Witness expenses: Travel, accommodation, and loss-of-time payments for witnesses.
For a trial running three to five days, total legal costs (solicitor and barrister) typically fall between $150,000 and $350,000 per side. Longer or more complex trials — involving multiple publications, extensive cross-examination, or appeals — can exceed $500,000.
Who Pays? Costs Orders in Defamation
The general rule in Australian courts is that costs follow the event — the losing party pays the winning party's costs. In practice, a "party and party" costs order typically recovers 60 to 70 per cent of the successful party's actual costs, leaving a gap that must be borne by the winner.
However, the Defamation Act contains specific costs provisions that can shift the balance dramatically:
- Section 40(2)(a): If a plaintiff succeeds and the defendant unreasonably failed to make or accept a settlement offer, the court must assess costs on an indemnity basis — meaning the defendant pays close to the plaintiff's full legal bill.
- Section 40(2)(b): If a defendant succeeds and the plaintiff unreasonably refused a settlement offer, the court must assess costs on an indemnity basis against the plaintiff.
Indemnity costs are significantly higher than standard costs. In Prouten v Buxton [2024] NSWSC, the unsuccessful plaintiff was ordered to pay the defendant's costs of $178,223.50 — a sum the Court acknowledged was "devastating" for an ordinary member of the community.
The practical lesson is clear: unreasonably refusing a settlement offer creates an acute costs risk. This is why settlement strategy must be front-of-mind from the earliest stage of any defamation dispute.
The Damages Cap: Is It Worth It?
As at 1 July 2025, the statutory cap on damages for non-economic loss in defamation proceedings is $500,000. This cap is indexed annually and applies uniformly across all Australian jurisdictions. Damages for actual economic loss (such as lost income or business revenue) are uncapped and may be claimed in addition.
It is important to weigh the potential damages recovery against the likely costs of litigation. If the defamatory publication caused moderate reputational harm and damages are likely to be assessed at $30,000 to $50,000, spending $200,000 to get to trial is rarely a sound commercial decision — unless the case also involves an injunction, a vindication objective, or a significant economic loss claim that sits outside the cap.
A candid early assessment of the likely damages range, combined with realistic costs estimates, is essential to making a rational litigation decision.
How to Manage and Reduce Costs
In my experience, the following strategies are the most effective at keeping defamation costs proportionate:
- Act early and strategically. A well-crafted concerns notice, issued promptly, resolves many matters without litigation. Delay increases costs and complicates evidence preservation.
- Choose the right forum. The Federal Court, Supreme Courts, and in some cases District or County Courts each have different procedural requirements and costs implications. Forum selection matters.
- Use the offer-to-make-amends regime. Whether you are plaintiff or defendant, engaging meaningfully with the statutory settlement process can avoid the enormous expense of trial — and protect you from adverse indemnity costs orders.
- Embrace mediation. The majority of defamation matters that proceed to mediation settle. A skilled mediator and well-prepared submissions can resolve even entrenched disputes at a fraction of trial costs.
- Agree on costs arrangements up front. Discuss fee structures with your lawyer at the outset — whether hourly, fixed-fee for defined stages, or a capped arrangement. Transparency about costs is essential.
- Consider the serious harm threshold. Since the 2021 reforms, a plaintiff must establish that the publication has caused, or is likely to cause, serious harm to reputation. If serious harm is doubtful, the economics of proceeding may not stack up.
