Most of us spend a portion of our lives on social media, right? In particular, Facebook has transformed the way people communicate and the way reputations are damaged. Social media defamation is now one of the most common forms of reputational harm in Australia. A defamatory post can reach hundreds or thousands of people within hours, and unlike a spoken comment, it leaves a permanent record visible through search engines.
In Australia, defamation law applies to online publications in exactly the same way it applies to print or broadcast media. If someone has published false and damaging statements about you on Facebook or other online platforms, you have legal options.
This factsheet explains what Facebook defamation is, who can be held liable, how to preserve evidence, how to pursue removal, and what the litigation process looks like if legal action becomes necessary.

Key Takeaways
- Australian defamation law applies fully to social media. A Facebook post, comment, or share can ground a legal claim.
- The serious harm threshold must be met, not every offensive or embarrassing post is necessarily defamatory in law.
- Time limits are strict. You generally have one year from the date of publication to commence proceedings, so early legal advice is critical.
- Evidence disappears. Content can be deleted, edited, or set to private at any time. Screenshot and preserve everything immediately.
- Australian courts have awarded substantial damages for online defamation, including $279,000 for a Queensland Facebook case in 2023 and $750,000 in an online review case in 2020.
- O’Brien Criminal & Civil Solicitors have extensive experience representing clients in defamation matters involving social media.
What Constitutes Defamation on Facebook
Defamation occurs when a false statement is published that damages a person’s reputation. On Facebook, defamatory content can take various forms:
- a post on a personal page,
- a defamatory comment on someone else’s post,
- a shared article with a defamatory caption, a message in a Facebook group,
- or content in a Facebook Story.
The legal elements a plaintiff must establish are:
- The statement was published, posted on Facebook or otherwise communicated to at least one other person
- The statement identifies you, or is reasonably understood by an ordinary reasonable reader to refer to you
- The statement has caused, or is likely to cause, serious harm to your reputation
That third element is important. Under Australian defamation law as it has applied since the Stage 1 reforms commenced on 1 July 2021, a person no longer has a cause of action unless the publication caused or is likely to cause serious harm to their reputation. This serious harm requirement is designed to filter out trivial claims and protect free speech, while still providing genuine redress for real reputational damage.
Note also that large corporations and other organisations with 10 or more employees generally cannot sue for defamation, if a business is affected, your lawyer can advise whether a defamation claim is available or whether another cause of action may apply.
On the question of truth: truth is a complete defence to a defamation claim, not something the plaintiff must disprove up front. If a defendant can prove that the published statement was substantially true, they will not be liable. This is why the factual basis for any claim matters from the outset.
Who Can Be Sued for Facebook Defamation
More than one person may be legally responsible for defamatory material published on Facebook. The following people can be sued for Facebook defamation.
The original poster is always the primary potential defendant, they authored and published the defamatory statements.
Anyone who shares or reposts the content can also be liable. Sharing is republication, and each such publication is a fresh defamatory publication for defamation purposes.
Facebook page administrators may have exposure in some circumstances. In Fairfax Media Publications Pty Ltd v Voller [2021] HCA 27, the High Court held by a 5:2 majority that media outlets which created and administered public Facebook pages, and actively encouraged third-party comments on those pages, were publishers of the resulting comments. The case established that any voluntary act of participation in the communication of defamatory content can give rise to liability, regardless of whether the defendant knew the specific content was of a defamatory nature.
Suing the Meta (Facebook) organisation
Stage 2 reforms in NSW (from 1 July 2024) and Victoria (from 11 September 2024) introduce potential defences for various social media platforms classified as “digital intermediaries.” These defences may be available where a platform has a compliant complaints system and takes reasonable steps to deal with defamatory content once properly notified. However, the exact operation and availability of these defences is more nuanced than a simple on/off switch — it depends on the jurisdiction, the platform’s specific complaints processes, identity disclosure requirements, the nature of the steps taken, and the particular facts of the case.
These Stage 2 reforms are not yet in force across all Australian jurisdictions: Queensland, Western Australia, the Northern Territory and South Australia have not yet fully enacted them. This means the applicable law on platform liability may vary significantly depending on where the publication occurred and where proceedings are brought.
Preserving Evidence of Facebook Defamation: How to make a defamation claim in NSW
If you see defamatory content about you on Facebook, preserve it immediately. Offending content can be deleted, edited, or made private at any time, and once it is gone it becomes significantly harder to prove what was said and when.
Screenshots: Take full screenshots of the defamatory post, capturing the author’s name, profile, date of publication, and any comments. Do this across multiple devices if possible and store copies in more than one location.
Record the URL: Copy the direct link to the post from your browser address bar. This documents exactly where the content appeared.
Metadata and context: Note the exact date and time of publication, the visibility settings (public, friends, group), and the number of likes, shares, or comments. This information is relevant to establishing the extent of publication.
Web archiving: Consider archiving publicly visible content using a service such as the Wayback Machine. This is not always possible for restricted or group content, but it creates an independent record for publicly accessible pages.
Do not engage: Avoid liking, commenting on, or replying to the defamatory post. Engagement can complicate your legal position and may be used against you.
Forensic certification: Your lawyer can engage digital forensics experts to produce certified copies of online content. These carry substantially more evidentiary weight than personal screenshots and are much harder to challenge for authenticity.
Requesting Removal from Facebook of Defamatory Content
Before commencing formal legal proceedings, you may attempt to have the content removed through Facebook’s reporting system. Facebook’s Community Standards prohibit harassment and harmful content, which can cover some forms of defamation.
To report a post:
- Click the three dots (menu) on the post or comment
- Select “Find support or report post”
- Choose “It’s abusive or harmful” or the closest applicable category
- Follow the prompts and submit the report
Facebook’s review processes are not always fast or consistent, and moderators may not identify subtle or contextual defamatory conduct. If the platform does not remove the content, your lawyer can send a formal legal takedown notice, which carries considerably more weight and puts Facebook on notice of potential liability. For posts falling within the scope of the Stage 2 digital intermediary reforms, a written complaint in the correct form activates Facebook’s seven-day removal obligation and its obligations under the defence framework.
If all else fails, courts can issue a court order requiring digital intermediaries to prevent access to defamatory information, even where the platform is not itself a party to the proceedings.
The Concerns Notice Process in NSW Defamation Matters
Before commencing defamation proceedings in Australia, you are required by law to first serve a Concerns Notice on the person responsible for publishing the defamatory material. This is a mandatory procedural step.
A valid Concerns Notice must:
- Identify the specific defamatory statements you consider actionable, including the defamatory imputations you say those statements carry
- Explain the serious harm caused or likely to be caused to your reputation, including any significant harm to your professional reputation
- Specify where the material was published, including the Facebook URL
- Give the publisher a genuine opportunity to respond
What happens after service:
The recipient has 28 days to make an “offer of amends”, which might include a correction, an apology, or a payment of compensation. Accepting a reasonable offer can resolve the matter without litigation. If a person makes an unreasonable rejection of an offer of amends, that is itself a factor courts consider in subsequent proceedings.
If no acceptable offer is made, you can commence proceedings. You must wait a minimum of 28 days after serving the Concerns Notice before filing.
Time limits: A defamation claim must generally be commenced within one year from the date of first publication. Under the “single publication rule” introduced in the Stage 1 reforms, the limitation period runs from the date the material was first published online, not each time it is accessed. The court has limited discretion to extend this to three years in appropriate circumstances, but you should not rely on that possibility.
Timeline for Action
| Timeframe | Action Required |
| Immediately (Day 1) | Screenshot and preserve all defamatory content; record the URL and metadata; consult a defamation lawyer; do not engage with the post |
| Within days | Attempt removal through Facebook’s reporting process; archive publicly visible content |
| Within 1–2 weeks | Your lawyer sends a formal legal takedown notice to Facebook if the content remains |
| Within 28–56 days | Serve a Concerns Notice on the publisher (author, page admin, or person who shared the content) |
| 28+ days after Concerns Notice | Publisher has 28 days to respond with an offer of amends; if no acceptable offer is made, proceedings can commence |
| Within 1 year of publication | Court proceedings must be commenced within the limitation period |
Damages and Compensation
If defamation is established, the court can award damages to compensate for the harm suffered. Awards vary significantly based on the circumstances and are not predetermined. Courts consider:
- Your professional reputation and standing before the publication
- The seriousness of the imputations conveyed
- The extent of publication, how many people saw or shared the content
- The conduct of the defendant, including whether they acted with malice, refused to apologise, or continued republishing
- Emotional distress and injury to feelings
- Economic losses such as lost income, lost clients, or damage to business dealings
Courts have made substantial awards in Australian online defamation cases. In Rodgers & Anor v Gooding [2023] QDC 115, a Queensland woman was ordered to pay $279,000 in damages, including aggravated damages, after making false allegations against her neighbours in a community Facebook group.
In Cheng v Lok [2020] SASC 14, an Adelaide barrister was awarded $750,000 after a woman who had never been his client posted a series of false and damaging statements about his practice on Google. Both cases illustrate that courts take online defamation seriously and are prepared to award compensation that reflects the real-world consequences of spreading false and damaging statements designed to damage someone’s reputation.
Frequently Asked Questions
Can I sue someone for a defamatory Facebook post?
Yes, provided the post has caused or is likely to cause serious harm to your reputation, identifies you, and was published to at least one other person. Defamation law applies to Facebook posts in the same way it applies to newspapers or television, provided the serious harm threshold is met. Because that threshold must be established, it is worth getting early legal advice to assess whether your situation qualifies before investing time and money in a defamation action.
It is also worth noting that not all entities can sue for defamation. Large corporations, those with 10 or more employees, generally cannot bring a defamation claim unless specific circumstances apply. Smaller businesses, not-for-profits, and individuals are not subject to this restriction. If the person or entity affected by the Facebook post is a business, your lawyer can advise whether a defamation action is available or whether another cause of action, such as injurious falsehood, may be more appropriate. Defences such as honest opinion, contextual truth, and public interest may also be raised by a defendant, so court action should only be pursued on proper legal advice.
Who is responsible in NSW defamation matters, the person who posted or the person who shared it?
Both can be liable. The original poster is the primary defendant. Anyone who shares or reposts the content is also a publisher and may be sued for that republication separately. A Facebook page administrator may also have exposure for such defamatory actions in some circumstances, following the principles established in Fairfax v Voller, but this depends on the facts of each case. Your lawyer can advise on the best respondents to pursue.
How do I preserve evidence of Facebook defamation?
Take full screenshots immediately, including the author’s name, date, post text, and any comments. Save the URL directly from your browser. Note the date, time, and visibility settings. Do not like, comment on, or engage with the post. Your lawyer can also engage forensic experts to produce certified copies, which carry greater evidential weight in proceedings.
What damages can I claim?
Damages depend on the facts of your case. Courts award compensation for harm to reputation, emotional distress, and economic loss such as lost income or lost business. Awards in Australian online defamation cases have ranged from modest amounts to several hundred thousand dollars in serious cases. Your lawyer will assess the likely value of your claim based on the nature of the imputations and the extent of harm suffered.
What if Facebook does not remove the content?
If the platform’s internal reporting process fails, your lawyer can send a formal legal takedown notice. Under the Stage 2 digital intermediary reforms (in NSW, ACT and Victoria), a written complaint in the correct form requires Facebook to take access prevention steps within seven days or lose its defence. Courts also have the power to order non-parties, including social media platforms, to prevent access to defamatory content regardless of whether the platform is a defendant in the proceedings.
Can I remain anonymous if I pursue a defamation claim?
Defamation proceedings are generally heard in open court and parties are identified in judgments. There are limited exceptions where courts may suppress identifying information. Your lawyer can advise whether any suppression orders may be appropriate in your circumstances.
What to Do Now
Preserve evidence immediately. Content can disappear without notice. Screenshots, URLs, and metadata should be captured and stored the moment you become aware of the problem.
Consult a defamation lawyer promptly. The one-year limitation period runs from the date of first publication, not from when you discovered the content. Delayed advice narrows your options.
Do not engage with the post. Liking, commenting, or sharing, even in response, can complicate your position and potentially extend the chain of publication. Even responding to personal attacks in online posts can be used against you.
Report the content to Facebook using the platform’s own process, while your lawyer prepares more formal action in parallel.
Act on legal advice before making any public statements about the matter. What you say in response can affect your position in subsequent proceedings.
