Key Takeaways
Building companies with 10 or more employees generally cannot sue for defamation in Queensland due to the Defamation Act 2005 section 9 exclusion.
Forwarding or sharing a subcontractor's defamatory social media post to a superintendent, even to rebut it, triggers a fresh publication and may expose the director to personal liability—though a carefully framed communication confined to persons with a direct contractual interest may attract the defence of qualified privilege under section 30.
Plaintiffs must demonstrate a "serious harm" threshold to pursue a claim, limiting legal action over trivial online grievances.
The defence of justification (truth) is often complex and costly to establish, making strategic de-escalation of the underlying payment dispute preferable to formal litigation.
A terminated subcontractor has just blasted your payment practices across an industry Facebook group, claiming your company routinely stiff-arms trades on progress claims. Within an hour, the project superintendent is calling to ask why the principal is seeing screenshots of the post. Your immediate instinct is to fire off a cease-and-desist letter or draft a point-by-point rebuttal to the superintendent to clear the company's name. However, attempting to control the narrative by sharing or formally addressing these online disputes can inadvertently trap you in secondary publication liability under Queensland defamation law.
The First 48 Hours: Assessing the Subcontractor's Defamatory Post
The reputational damage feels like it is escalating by the minute. Before you instruct your lawyer to draft a threatening letter or circulate a written rebuttal to stakeholders, you must answer a threshold question: does your company actually hold the legal standing to sue for defamation under Queensland law? If the answer is no—and for most mid-to-large builders it will be—then every dollar spent on defamation posturing is wasted, and your energy must pivot immediately to managing the commercial dispute.
Why the "Excluded Corporation" Test Dictates Your Next Move
A mid-to-large building company generally cannot commence a defamation claim due to strict statutory limitations. Section 9 of the Defamation Act 2005 (Qld) explicitly limits corporate defamation claims. As Australia's Unified Approach to Defamation outlines, the right to sue in order to protect a corporate reputation is restricted to very specific entities.
Under section 9 of the Defamation Act 2005 (Qld), a building company cannot sue for defamation to protect its reputation unless it qualifies as an excluded corporation, which generally means employing fewer than 10 staff and not being an associated entity of another corporation.
If your company employs 10 or more people and is not a not-for-profit entity, it holds no cause of action for defamation regarding the publication of defamatory matter. Note that "employee" under the Act is defined broadly to include any individual engaged in the day-to-day operations of the corporation (other than as a volunteer) who is subject to its control and direction—this can capture independent contractors. Part-time employees are counted as an appropriate fraction of a full-time equivalent.
Statutory Defamation Actions vs Commercial Contract Disputes
Successfully navigating a termination building contract dispute over a subcontractor's default does not establish grounds for a defamation claim. The two legal frameworks operate independently and protect entirely different rights.
A breach of contract dispute is assessed on the agreed contractual terms, payment schedules, and performance metrics. Conversely, a statutory defamation action hinges on public statements that damage reputation. Securing a favourable outcome in the commercial dispute does not create standing to sue for the social media post, just as a defamatory post does not invalidate the underlying contract termination. Directors must quarantine the contract dispute from the reputational fallout to avoid conflating the legal remedies.
The Danger of the "Empty Threat" Cease-and-Desist
Issuing a cease-and-desist letter on company letterhead often backfires if the building company employs 10 or more people. Educated respondents or their legal representatives guided by professional standards set by bodies like the Queensland Law Society will quickly recognise that the company lacks the statutory standing to actually commence proceedings. This reality turns the threat into an empty gesture, exposing the builder to counter-leverage and emboldening the subcontractor.
In practice, the pattern is remarkably consistent. A director sees a scathing post, calls their solicitor in a fury, and within 24 hours a letter goes out on firm letterhead demanding the subcontractor retract and apologise or face defamation proceedings. The problem is that nobody has turned their mind to whether the company actually has standing. When the subcontractor's solicitor responds—and they almost always do respond if they know the law—the reply is a one-paragraph letter citing section 9 and inviting the builder to commence proceedings they both know cannot be filed. At that point, the builder has handed the subcontractor a document that effectively proves the threat was hollow, which the subcontractor then screenshots and posts alongside the original grievance as evidence of attempted intimidation.
The reputational damage doubles overnight. Worse, the failed cease-and-desist can be deployed in any subsequent adjudication or Queensland Civil and Administrative Tribunal (QCAT) proceeding to paint the builder as a party that uses legal threats to suppress legitimate payment claims rather than addressing them on their merits. The tactical lesson is blunt: if your company employs 10 or more people, a defamation threat letter is not a weapon—it is a gift to the other side. The proper first step is always to confirm standing before any correspondence leaves the office, and if standing does not exist, the director's energy must immediately pivot to managing the commercial dispute rather than the social media post.
The Rebuttal Trap: Secondary Publication to the Superintendent
Your immediate instinct is likely to capture a screenshot of the offending post, attach it to an email, and send it directly to the principal or superintendent to prove the subcontractor is lying. While you understandably feel defensive and eager to clear your name with key stakeholders, this reactive step can inadvertently hand the subcontractor a new legal weapon. Repeating or circulating the very statement you are trying to suppress may trigger a statutory liability pathway by satisfying the publication element of a defamation claim.
How Forwarding the Post Creates Fresh Liability
Sharing a defamatory social media post to a project superintendent may constitute a fresh publication under Queensland law, potentially exposing the sender to secondary liability even if they did not author the original content.
Warning: Sharing, forwarding, or emailing a defamatory post to project stakeholders constitutes a fresh publication under Queensland law. Each new recipient represents an independent act of publication, and the sender—not the original author—bears liability for that dissemination. A director who attaches a screenshot of the subcontractor's post to an email addressed to the superintendent is personally exposed to a defamation claim by the subcontractor, regardless of the director's intention to rebut the content. Directors should consult Queensland building and construction lawyers before sending any disputed online content to third parties, and speak with our team regarding a safe correspondence strategy.
Navigating the Innocent Dissemination Defence
Section 32 of the Defamation Act provides a specific procedural mechanism to protect individuals who unknowingly share harmful content. It is a defence to the publication of defamatory matter if the defendant proves three cumulative elements: (a) they published the matter merely in the capacity of a subordinate distributor; (b) they neither knew, nor ought reasonably to have known, that the matter was defamatory; and (c) their lack of knowledge was not due to any negligence on their part. An individual who shares or reposts defamatory material may rely on this defence only if they satisfy all three limbs—acting merely in the capacity of, or as an employee or agent of, a subordinate distributor, having no actual or constructive knowledge the content was defamatory, and demonstrating their ignorance was not negligent.
In practice, this defence is almost certainly unavailable where a director knowingly forwards a subcontractor's grievance post to a principal. The director is aware the content is defamatory—that is precisely why they are rebutting it—which means limb (b) fails at the threshold. The innocent dissemination defence is designed to protect passive conduits such as internet service providers or newsagents, not active participants who deliberately circulate material they recognise as harmful to someone's reputation. Directors in this position must look to other defences, most notably qualified privilege under section 30 of the Defamation Act, which is discussed below.
Establishing the "Serious Harm" Element
To deter trivial claims over minor online grievances, recent legislative updates introduced a strict threshold for defamation actions. Under section 10A of the Defamation Act, it is an element (the serious harm element) of a cause of action for defamation that the publication of defamatory matter has caused, or is likely to cause, serious harm. A plaintiff cannot successfully sue for defamation over a social media post unless they can prove the post caused or is likely to cause serious harm to their reputation. For excluded corporations specifically, section 10A(2) imposes an additional requirement: harm to the reputation of an excluded corporation is not serious harm unless it has caused, or is likely to cause, the corporation serious financial loss.
This statutory trigger prevents parties from commencing litigation over minor venting on community forums that does not materially impact commercial standing or project prospects. For related considerations regarding the assessment of harm and financial exposure, directors should review the principles surrounding Aggravated Damages in Queensland: A Strategic Guide for Developers Facing Defamation.
Relying on the Justification Defence When the Dispute Escalates
If you are accused of publishing defamatory material—perhaps because you forwarded the subcontractor's claims to a principal to debunk them—you may need to formally defend your actions. You are now facing the stark financial reality of a legal fight. Before allowing the dispute to deepen, you must understand the heavy evidentiary burden required to prove that the claims were true, and weigh the cost of defending your reputation against the cost of simply resolving the underlying contract issue.
Proving Substantial Truth in a Payment Dispute
A builder or subcontractor sued for defamation can successfully defend the claim by proving the defamatory statements they posted were substantially true.
Under Queensland defamation law, a party can successfully defend a claim by proving the defamatory imputations regarding the building contract dispute are substantially true.
Under Section 25 of the Defamation Act, it is a defence to the publication of defamatory matter if the defendant proves that the defamatory imputations carried by the matter of which the plaintiff complains are substantially true. However, establishing justification requires robust documentary evidence demonstrating the factual accuracy of the underlying payment grievance. A director attempting to mount this defence must present compelling records of the building contract dispute, including payment schedules, variations, and communications. They must also act within the strict timeframes governing civil actions under the Limitation of Actions Act 1974 (Qld). Relying on substantial truth is a complex procedural mechanism that often forces the parties to litigate the underlying commercial dispute within the defamation proceedings.
The Commercial Reality of Defending a Subbie's Claims
Subcontractors who take to social media to "name and shame" almost universally believe they are bulletproof because the money is genuinely owed. The logic feels intuitive—if the claim is true, there is no defamation. But the gap between something being true and proving it is substantially true in court proceedings is vast and expensive. Justification is not simply a matter of waving an unpaid invoice at a judge. The defendant must prove the precise imputations conveyed by the post, not merely the general flavour of the complaint. If the post says the builder "routinely stiff-arms trades," the subcontractor must prove that systemic conduct, not just their own unpaid claim.
The evidentiary cost of marshalling witnesses, subpoenaing payment records across multiple projects, and engaging forensic accounting expertise to substantiate a broad allegation can, depending on the complexity of the matter, reach $80,000 to $150,000 or more before trial. A subcontractor already chasing $40,000 in unpaid progress claims simply cannot absorb that litigation spend. Head contractors with deeper pockets know this, and in practice the defamation suit—or the credible threat of one from a director who does have personal standing even where the company does not—becomes a parallel pressure point that forces the subcontractor to agree to mutual non-disparagement undertakings as part of a commercial settlement.
The subcontractor ends up deleting the post and signing a deed of release, not because the post was false, but because they cannot afford to prove it was true. Directors considering this strategy should be clear-eyed about proportionality: pursuing a defamation claim purely as a silencing mechanism carries its own risks, including adverse costs orders if the claim is struck out for abuse of process, and potential regulatory scrutiny if the conduct is seen as leveraging legal proceedings to suppress payment claims in contravention of the spirit of security of payment legislation.
Strategic Alternatives to Defamation Litigation
Defamation proceedings are notoriously slow, public, and expensive, making them a poor vehicle for resolving what is ultimately a construction payment dispute. You have now moved past the initial reactive anger and must pivot to practical risk management. Your focus should immediately shift to quarantining the commercial damage and addressing the root cause through appropriate industry procedural mechanisms, protecting your commercial relationships without incurring massive legal fees.
Managing the Project Principal's Concerns Directly
When addressing a subcontractor's public allegations with a superintendent, building directors should rely on verified payment schedules and progress reports rather than forwarding the disputed claims. To effectively manage the project principal's concerns without risking secondary defamation liability, consider the following practical steps:
Present objective, contractually compliant progress updates that focus on project milestones rather than acknowledging the subcontractor's social media posts.
Issue formal payment schedules that clearly detail the reasons for withholding any funds, aligning with industry best practices endorsed by Master Builders Queensland.
Ensure all site operations maintain strict compliance with the regulatory expectations of the Queensland Building and Construction Commission (QBCC), demonstrating to the principal that your company operates professionally regardless of online noise.
Utilising QCAT for the Underlying Payment Dispute
Shifting the battleground away from defamation and focusing on the actual commercial dispute via the Queensland Civil and Administrative Tribunal (QCAT) often provides a much faster and cost-effective resolution to the subcontractor's grievances. Rather than engaging in a protracted Supreme Court battle over reputation, directors can utilise the Building Industry Fairness Act guide framework to compel the subcontractor to formally substantiate their financial claims. Redirecting the conflict into formal building dispute resolution Queensland channels strips the emotion from the dispute and grounds it in contractual reality.
The strategic calculus here is straightforward but not without risk: a subcontractor who is willing to post inflammatory claims on Facebook is often far less willing to file a formal application and swear to the accuracy of their figures in a tribunal. Conversely, if the subcontractor's claim has genuine merit and is well-documented, directing the dispute into QCAT may accelerate rather than suppress the builder's obligation to pay—directors must be prepared for that outcome and ensure their own payment records withstand scrutiny. QCAT forces specificity—the subcontractor must identify the precise invoices, the contractual basis for each claimed amount, and the dates on which payment became due. Vague grievances about being "ripped off" collapse quickly when a member asks for the variation directive or the signed progress claim.
In practice, many subcontractors who are vocal online quietly drop or substantially reduce their claims once they are required to particularise them under oath. The builder, meanwhile, gains a procedural forum where verified payment schedules and contractual documentation carry far more weight than social media rhetoric. The filing fees are modest, the timeframes are compressed compared to Supreme Court proceedings, and critically, the outcome addresses the actual commercial irritant driving the online behaviour. Once the money dispute is resolved—or the subcontractor's claim is formally dismissed—the social media post loses its oxygen. A QCAT determination that the builder paid in accordance with the contract is worth more to your superintendent relationship than any defamation judgment ever could be.
Conclusion
The initial shock of seeing a terminated subcontractor trash your building company on Facebook can quickly drive directors toward reactive, high-risk decisions. However, as Queensland law dictates, firing off a defamation threat is often an empty gesture if your company employs 10 or more staff and fails the "excluded corporation" test. Worse still, attempting to clear your name by forwarding the defamatory post to your project superintendent may inadvertently trigger a fresh publication, exposing you to personal liability even if you were just trying to set the record straight.
Defamation law is a blunt and exceptionally expensive instrument that rarely serves the commercial realities of the construction industry. Where a director must communicate with a superintendent about the allegations, the safest path is a carefully framed summary—never a forwarded screenshot—confined to persons with a direct contractual interest, which may attract qualified privilege under section 30. The heavy evidentiary burden required to prove the "serious harm" threshold and the "justification" of substantial truth means that reputational disputes can easily consume project profits and executive focus.
Rather than taking the bait online or risking secondary publication, directors must actively quarantine the reputational fallout from the underlying contract issue. The most effective forward-looking action is to redirect the subcontractor's financial grievances into formal commercial channels, such as a QCAT application or a BIF Act adjudication, forcing them to substantiate their claims with hard evidence rather than social media rhetoric.
FAQs
Can my Queensland building company sue a subcontractor for defamation?
Perhaps. Under section 9 of the Defamation Act 2005, a company that employs 10 or more people—broadly defined to include contractors subject to its control and direction—cannot sue for defamation unless it is a not-for-profit. Directors of excluded corporations should focus on resolving the underlying commercial dispute through adjudication or QCAT rather than pursuing a defamation claim the company lacks standing to bring.
Does sharing a defamatory post about my business create legal risk?
Yes, forwarding or emailing a defamatory post to a third party, such as a project superintendent, constitutes a fresh publication. This secondary publication can expose the sender to personal defamation liability, even if they did not author the original online content. A director who must address the allegations with a superintendent should summarise the claims in neutral terms rather than attaching the original post, and confine the communication to persons with a direct contractual interest, which may support a defence of qualified privilege under section 30 of the Defamation Act 2005.
What is the "serious harm" threshold in Queensland defamation claims?
Under section 10A of the Defamation Act 2005, a plaintiff must prove that the publication of the defamatory matter has caused, or is likely to cause, serious harm to their reputation. This statutory requirement limits the ability to pursue litigation over trivial online grievances that do not materially impact commercial standing.
How does the defence of innocent dissemination work for online posts?
Section 32 of the Defamation Act 2005 provides a defence if the defendant proves three cumulative elements: (a) they published the matter merely in the capacity of a subordinate distributor; (b) they neither knew, nor ought reasonably to have known, that the matter was defamatory; and (c) their lack of knowledge was not due to any negligence on their part. An individual sharing a post may rely on this defence only if they satisfy all three limbs, including demonstrating they had no actual or constructive knowledge the content was defamatory.
Can a director rely on qualified privilege when addressing a subcontractor's allegations with a superintendent?
Potentially, yes. Under section 30 of the Defamation Act 2005, a director may have a defence of qualified privilege if the superintendent has a legitimate interest in the information, the communication is made in the course of providing information on that subject, and the director's conduct is reasonable in the circumstances. To maximise the prospects of this defence, the director should summarise the allegations in neutral language rather than forwarding the original post, confine the communication to those with a direct contractual interest, and avoid any language motivated by a desire to damage the subcontractor. The defence is defeated by proof of malice.
Can I defend a defamation claim by proving my online statements were true?
Yes, under section 25 of the Defamation Act 2005, a party can defend a claim by proving the defamatory imputations are substantially true. However, establishing this justification defence often requires extensive documentary evidence and can be a costly, protracted process.
Should I send a cease-and-desist letter for a bad Google review?
Issuing a formal notice can backfire if your company is not an excluded corporation under the Defamation Act 2005. Because companies with 10 or more employees generally lack standing to sue for defamation, the threat may be ignored by legally represented parties. Directors should typically consider resolving the underlying commercial dispute through appropriate legal channels instead.
