People targeted by damaging online content reach for "defamation" early. It's a serious-sounding word that captures the feeling of being wronged.
But "feels defamatory" and "is legally defamatory" are very different things in Australian law. Most matters that feel like defamation aren't. Of the ones that are, only some are worth pursuing through the court system. Getting the threshold right early saves money, time, and disappointment.
This isn't legal advice. ORMA isn't a law firm. Understanding the actual shape of Australian defamation law lets you have a more useful conversation with counsel when the time comes.
The legal framework
Australian defamation is governed by state and territory legislation, materially aligned across jurisdictions since the 2021 uniform reforms. The relevant statute in NSW is the Defamation Act 2005, with equivalent acts in VIC, QLD, WA, SA, TAS, ACT, and NT.
The 2021 reforms (taking effect July 2021) introduced the most significant changes in a generation: a statutory serious-harm test, mandatory pre-action concerns-notice processes, and tightened defence regimes. The practical effect is that low-grade complaints face higher dismissal thresholds while well-founded matters proceed more efficiently.
The statute of limitations is one year from publication, extendable to three years only in exceptional circumstances. For online content, courts have moved toward treating the original posting date as the relevant trigger rather than each subsequent download. Old content that's been live for years is often past the window.
What has to be proved
Australian defamation requires three elements, all of which must be established.
Publication. The statement must have been communicated to at least one person other than the subject. Online posts that anyone can read clearly qualify. Private messages between two parties don't. Anything in between (closed forums, private group chats) gets assessed on the facts.
Identification. The statement must identify the subject. Naming is the clearest case. Identification by description, photo, or context also qualifies. A vague reference that could apply to many people generally doesn't.
Defamatory imputation. The statement must convey a meaning that would lower the subject in the eyes of ordinary reasonable members of the community. The test is objective (what would an ordinary reader take from it), not subjective (what did the speaker intend).
If any one element fails, there's no defamation. Most rejections at publishers and many dismissals at the concerns-notice stage turn on identification or imputation problems, not on the truth or falsity of the content.
The serious-harm test
Introduced in the 2021 reforms, the serious-harm test requires the plaintiff to show the publication caused (or is likely to cause) serious harm to reputation. For corporations, the threshold is higher: serious financial loss.
This is a substantive shift. Before 2021, harm was presumed once the other elements were established. Now it has to be proved with evidence: reduced business, lost employment opportunities, social ostracism, documented impact. Soft complaints ("it's embarrassing") don't pass the threshold.
The serious-harm test is the most common reason defamation matters that look strong on paper fail. Counsel will press hard on what evidence of harm actually exists before taking a matter forward.
Defences
Even where the elements are met and serious harm is established, several defences can defeat a claim.
Truth (justification). If the imputation is substantially true, there's no defamation. The burden is on the defendant to prove truth, which is why publishers stand by their reporting only when they're confident the underlying facts are sound.
Honest opinion. A statement of opinion (not fact) on a matter of public interest, based on accurate underlying facts, is protected. The line between opinion and fact is heavily litigated. Even strong opinion is generally protected if the factual basis is clear.
Qualified privilege. Statements made in certain contexts (employer references, complaints to authorities, communications between parties with a shared interest) attract qualified privilege. This is the basis for many newsroom defences of investigative reporting.
Public interest (the new defence). Introduced in the 2021 reforms, a public-interest defence covers reasonable publication on matters of public concern. The defendant must show they reasonably believed publication was in the public interest. This codifies and extends what was previously the common-law Lange defence.
Absolute privilege. Statements in parliament, in court proceedings, and in certain official capacities are absolutely immune. Reports of these (Hansard, court judgments) are also protected.
The combination of these defences means publishers in well-resourced newsrooms successfully defend most defamation claims that reach trial.
The concerns-notice process
Since 2021, sending a concerns notice is a precondition to court proceedings in most cases. The process is structured.
The plaintiff sends a written concerns notice specifying the published matter, the imputations they say are defamatory, and the basis for the serious-harm claim. The publisher has 28 days to respond with an offer to make amends. The offer can include correction, apology, removal, payment of reasonable expenses, and (for serious matters) damages.
If a reasonable offer is made and accepted, the matter resolves. If a reasonable offer is made and rejected, that becomes a defence in any subsequent proceedings. If no offer or an inadequate offer is made, the plaintiff can proceed.
Most defamation matters in Australia resolve at the concerns-notice stage. Court proceedings are expensive and uncertain. Settlement through the concerns-notice mechanism is the more common outcome.
What's NOT defamation
A few categories worth understanding because they catch out plaintiffs constantly.
Mere opinion or criticism. A negative review, a critical blog post, an unfavourable rating are usually opinion and protected. "I had a bad experience" is opinion. "X embezzled funds" is a factual claim that needs to be true.
Generalised statements. "Doctors in this area are terrible" doesn't defame any specific doctor. Identification is required.
Satire and parody. Clearly satirical content that no reasonable reader would take as fact is generally protected, though the line can be litigated.
Statements of fact that are true. Truth is an absolute defence. Coverage of a conviction, a court judgment, an ASIC banning order is not defamatory simply because it harms the subject.
Communications outside Australia in specific circumstances. Australian courts can sometimes hear defamation matters involving overseas publishers, but jurisdiction issues complicate enforcement.
When ORMA fits in
For matters that do qualify as defamation, ORMA's role is the platform-side coordination and the suppression work that runs in parallel with whatever legal pathway counsel is pursuing.
Legal action takes time. Even successful matters can sit through 6 to 18 months of process. During that window, the defamatory content is often still live and ranking on branded searches. Suppression work over the same period can significantly reduce the visible damage while the legal pathway resolves.

Getting started
If you're trying to decide whether a piece of content is realistically actionable as defamation, the most useful next step is a structured assessment of the content itself (free, no obligation) combined with a conversation with a defamation lawyer. ORMA does the former. Counsel does the latter. Start with the assessment and we'll be honest about whether the matter looks like defamation or whether suppression alone is the workable path.
