Contract Drafting Traps: Can Your Water Contract Indemnity Void QLD Proportionate Liability?

Q: Can an indemnity clause in a water infrastructure contract transfer WHS duties?

No. Section 272 of the Work Health and Safety Act 2011 (Qld) expressly voids any contractual term that purports to transfer a statutory safety duty to another person. A principal cannot rely on a broad indemnity to avoid their non-delegable health and safety obligations.

KEY TAKEAWAYS

Broad indemnity clauses in Queensland government water contracts may not effectively transfer all commercial and safety risks due to strict statutory prohibitions.
Queensland is the only Australian jurisdiction that does not permit parties to contract out of the Civil Liability Act 2003 proportionate liability regime, so a purported opt-out in a water contract is generally ineffective and the statutory apportionment defence should survive.
Agreeing to indemnify a principal for workplace health and safety penalties is not just commercially dangerous—it is a direct offence under the Work Health and Safety Act 2011 (Qld).
Negotiating specific financial liability caps and carving out statutory non-delegable duties is essential before executing bespoke infrastructure agreements.

The tender documents for a new regional pump station have just landed on your desk, but the commercial terms contain a fatal trap. The local government principal has inserted a sweeping indemnity clause that demands your firm cover all costs, claims, and regulatory penalties arising from site operations—effectively treating your balance sheet as their primary insurance policy. The deadline to submit your bid is ticking, and you need to know exactly which of these risks can actually be transferred by contract and which are legally void. This article breaks down how Queensland's statutory frameworks limit absolute risk transfer and provides the tactical leverage you need to cap your exposure.

Unpacking the 100% Indemnity Demand in Government Water Contracts

You are staring at a bespoke council contract for a critical water treatment plant upgrade. The principal is demanding an absolute indemnity, expecting your civil contracting firm to assume all liability—even for a specialist process engineer's design failures. At this pre-execution stage, understanding which risks genuinely transfer and which are blocked by Queensland statute dictates your profit margin and business survival.

Separating Contractual Indemnities from Statutory Liability Caps

A contractual indemnity is designed to function as a private agreement to transfer financial risk from one party to another. However, while freedom of contract allows parties to allocate commercial risk between themselves, overriding state legislation can render this clause unenforceable.

In Queensland water infrastructure contracts, a broad contractual indemnity clause cannot override mandatory statutory protections found in the WHS Act, the Queensland Building and Construction Commission Act 1991 (Qld) (QBCC Act), or Civil Liability Act.

The kind of contractual indemnity a Queensland court will enforce is one that respects these legislative boundaries, rather than attempting to blanket all project liabilities under a single assumed-risk provision.

The Hidden Cost of Contracting Out of Proportionate Liability

Example: Consider a scenario where a civil contractor signs a water infrastructure contract containing a clause that purports to contract out of the Civil Liability Act 2003 (Qld) proportionate liability regime. In most Australian jurisdictions such a clause would shift the risk, and a principal facing a catastrophic pipe failure caused by a third-party consultant's flawed specification could pursue the civil contractor for 100% of the damages, bypassing the consultant entirely. Queensland, however, is different.

Section 7(3) of the Civil Liability Act 2003 (Qld) deliberately withholds the proportionate liability provisions from the freedom parties otherwise have to make their own contractual arrangements, with the result that a purported opt-out is generally ineffective. In practice this means the statutory apportionment defence should remain available to the contractor even where the contract attempts to exclude it — so the "you wear the entire $5 million rather than your just and equitable share" outcome that a principal may be counting on is far harder to achieve in Queensland than the drafting of the clause suggests. The practical risk therefore lies less in a valid opt-out and more in a contractor being pressured to settle, or funding rectification up front, without appreciating that the defence still exists.

Why You Must Assess Exposure Before Execution

Signing an unamended indemnity first and fighting its enforceability later often leads to uninsured losses. Before execution, contractors should conduct several critical assessments to ensure they are not assuming unmanageable contractual liabilities:

Verify alignment between the proposed indemnity and your contract works insurance, as policies typically exclude liabilities assumed by contract that would not exist at common law.
Scrutinise the terms for any attempt to contract out of proportionate liability, and treat it as a red flag to raise even though section 7(3) of the CLA means such a clause is generally ineffective in Queensland.
Identify any clauses purporting to cover regulatory fines or workplace safety penalties, which are legally invalid.
If the principal refuses to amend sweeping indemnity demands, get legal advice to negotiate specific financial liability caps and carve-outs.

How the Civil Liability Act Restricts Blanket Design Indemnities

When a pump station process fails due to a flawed engineering specification, an unamended indemnity clause might suggest you foot the entire rectification bill. But you may not have to. Queensland's statutory apportionment regime is designed to spread blame fairly between everyone at fault — which directly clashes with a principal's demand that you carry the loss alone.

The Operation of Section 31 on Apportionable Claims

The CLA outlines the primary legislative framework governing civil liability and negligence apportionment in Queensland. When a dispute involves concurrent wrongdoers on a Queensland construction project, the legislation provides a statutory mechanism designed to prevent one party from shouldering the entire financial burden of a shared fault. Specifically, section 31 of the CLA states that "the liability of a defendant who is a concurrent wrongdoer in relation to the claim is limited to an amount reflecting that proportion of the loss or damage claimed that the court considers just and equitable".

Critically, Queensland does not allow parties to bargain this protection away. Section 7(3) of the Act extends the parties' freedom to make their own contractual arrangements to most matters the Act governs, but expressly excludes the proportionate liability provisions — making Queensland the only Australian jurisdiction in which a contractual opt-out from proportionate liability is not permitted.

In plain terms: if a consultant's design caused the failure, section 31 is the mechanism that can stop the principal recovering the consultant's share from you — and in Queensland, unlike other states, a contract term that purports to opt out of that mechanism is generally ineffective.

This statutory limit inherently frustrates the enforcement of absolute back-to-back indemnity clauses. Because section 7(3) withholds the proportionate liability provisions from the parties' freedom of contract, an attempt to opt out of the regime in a Queensland contract is generally ineffective, and the section 31 defence should survive. If you face a principal attempting to enforce an unamended indemnity, consulting an experienced Queensland commercial lawyer is an essential step in assessing your true legal exposure.

Practitioner Insight: Contract Drafting to Reconcile Council Indemnities with Proportionate Defences

Most council and water authority contracts do not sit down and expressly opt out of the proportionate liability regime — which is just as well for principals, because in Queensland such an opt-out would generally be ineffective under section 7(3) in any event. What they do instead is bolt a broad indemnity onto a general conditions suite — often an AS 4300 or AS 4902 base heavily amended by special conditions — and assume the indemnity does the same job. It usually does not.

The gap opens up because the indemnity is drafted as a risk-transfer promise, while section 31 operates as a statutory apportionment defence at the point of judgment. Unless the special conditions contain clear words directed at excluding the Part governing apportionable claims, a contractor sued on the indemnity has real room to run the argument that its liability is still capped at its just and equitable share.

The tactical reality is that this argument is far stronger before you sign than after. If you can get the principal to acknowledge in the special conditions that the indemnity operates "subject to" the contractor's statutory apportionment rights, that piece of contract drafting converts a litigated argument into a drafting certainty. Even though a Queensland opt-out is generally ineffective under section 7(3), it is still worth confirming the contract does not contain a buried attempt at one — the phrase to hunt for is any clause purporting to exclude the operation of the Part relating to proportionate liability, or wording that fixes the contractor's liability "irrespective of the acts or omissions of any other party". Removing it up front spares you the cost and uncertainty of having to argue the point later.

The practical trap is the fit-for-purpose obligation sitting alongside the indemnity. A fit-for-purpose warranty can pull design risk back onto the contractor as a contractual promise, which may sit outside the apportionable claim framework entirely. When both appear in the one contract, treat the fit-for-purpose clause as the real exposure and negotiate it first.

The WHS Penalty Trap: Why Section 272A Voids Safety Indemnities

Government principals routinely fold regulatory penalties into the same catch-all indemnity used for costs and claims. Many directors do not realise that agreeing to indemnify a principal against WHS penalties is not merely a commercial risk — it is a direct statutory offence.

The Strict Prohibition Under Section 272

Section 272 of the Work Health and Safety Act 2011 (Qld) defines the strict statutory prohibition against contracting out of WHS duties in Queensland. The legislation expressly states that "a term of any agreement or contract that purports to exclude, limit or modify the operation of this Act or any duty owed under this Act or to transfer to another person any duty owed under this Act is void".

Section 272 of the WHS Act expressly voids any contractual term that purports to transfer a statutory safety duty to another person.

This renders any portion of a broad indemnity clause that attempts to outsource non-delegable workplace health and safety obligations legally useless, meaning principals cannot rely on contractual wording to shield themselves from regulatory enforcement.

The Offence of Indemnifying Against WHS Penalties

Warning: Contractors reviewing sweeping government indemnities must be aware that Queensland law now imposes serious consequences for attempting to transfer regulatory fines. Section 272A makes it a specific offence under Queensland law to enter into an arrangement that indemnifies a person for WHS penalties, stating that a person must not, "without reasonable excuse", "enter into a contract of insurance or other arrangement that purports to insure or indemnify a person for a liability for all or part of a monetary penalty under this Act".

The prohibition is not limited to entering into such an arrangement; it also extends to providing the insurance or indemnity, and to taking the benefit of it. Where an accused seeks to rely on a reasonable excuse, section 272A places the evidential burden of establishing that excuse on the accused. While the principal's indemnity clause is intended to shift all financial risk to the contractor, the enforceability of this clause is entirely defeated regarding safety fines, as the Act both voids these indemnities and penalises them. Directors who agree to these terms may expose themselves to targeted investigation and potential prosecution by Workplace Health and Safety Queensland.

Practitioner Insight: Navigating Unlawful Council Indemnity Demands

The recurring problem is not malice on the principal's side — it is template lag. Standard indemnity wording in bespoke water contracts frequently predates the section 272A prohibition and still sweeps up "all fines, penalties and regulatory costs" in a single catch-all. Contractors tendering to large water entities routinely sign these without anyone on either side registering that the penalty limb has become an offence rather than a commercial term.

The exposure is asymmetric and worth pausing on. Even if the indemnity is unenforceable as to the penalty, the act of entering the arrangement is itself the offence under section 272A, subject only to the "without reasonable excuse" qualifier the section contains — and the burden of raising that excuse falls on the accused. You do not get to rely on unenforceability as a defence — the risk crystallises at signing, not at the point someone tries to call on it.

The clean fix is narrow and rarely contentious. Rather than attacking the whole indemnity, propose a single carve-out confirming the indemnity does not extend to any monetary penalty imposed under the WHS Act. Framing it as bringing the contract into line with a statutory prohibition — not as a refusal to wear risk — is what gets it through a procurement team without escalation.

Two practical notes. First, insurers will not indemnify a WHS penalty in any event, so the carve-out costs the principal nothing they could have actually recovered. Second, watch the flow-down. This is the trap most head contractors miss.

Tactical Negotiation: Capping Your Indemnity Exposure Before Execution

Knowing that a blanket indemnity is flawed under statute does not mean you should blindly sign it and argue later. You must proactively carve out statutory protections and insert commercial liability caps to ensure your business remains viable if a catastrophic pipeline or treatment plant failure occurs.

Carving Out Statutory Building Defect Obligations

The QBCC Act imposes strict limitations on how construction defect liabilities can be allocated by contract. Section 108D of the QBCC Act explicitly provides that "a person can not contract out of the provisions of this Act". The strongest voiding language in the section, however, is confined to domestic building contracts: section 108D(2) renders a domestic building contract void to the extent it "purports to annul, exclude or change a provision of this Act", while section 108D(3) voids other agreements only to the extent they seek to exclude, change or restrict a right conferred under the Act "in relation to a domestic building contract". A council water treatment plant or pump station contract will ordinarily fall outside the definition of a domestic building contract, so a contractor cannot assume that section 108D operates on a commercial water infrastructure agreement in the same way it operates on domestic work. The threshold question is therefore whether any part of the contract engages the Act's domestic building contract provisions at all; where it does not, the general prohibition on contracting out in section 108D(1) must be read together with the more specific limbs in subsections (2) and (3) rather than treated as a stand-alone bar on every exclusion clause.

Under section 108D of the QBCC Act, a contractual indemnity that attempts to exclude or alter statutory obligations is void where the contract engages the Act's domestic building contract provisions; contractors on commercial water infrastructure work should confirm whether section 108D applies before relying on it.

Leveraging Statutory Protections in Tender Negotiations

Successfully pushing back against a principal's demand for an unamended indemnity requires a targeted approach during the pre-execution phase. To cap exposure and align the contract with the legal implications of breach, contractors should assess the following points:

Insurance Policy Alignment: Confirm that the requested indemnity does not extend beyond the coverage provided by your contract works and public liability policies, as assuming uninsured risks can lead to significant financial exposure.
Proportionate Liability Preservation: Although section 7(3) of the CLA means a purported opt-out is generally ineffective in Queensland, ensure the contract does not attempt one, so your liability is clearly restricted to your just and equitable share of any shared design or execution failure without you having to litigate the point.
WHS Penalty Exclusion: Require the principal to carve out monetary penalties for WHS breaches from the indemnity clause to avoid committing a statutory offence under section 272A of the WHS Act.
Engaging Legal Support: If the principal resists these essential amendments, consider obtaining advice from Queensland building and construction lawyers to negotiate enforceable commercial caps.

Why Ambiguous Indemnities Fail Under Common Law

Beyond statutory restrictions, the common law provides its own constraints that strictly limit the application of broad indemnities. Courts construe indemnity clauses strictly and, where they are ambiguous, against the party seeking to enforce the indemnity (a principle closely related to the contra proferentem rule). As demonstrated in Andar Transport Pty Ltd v Brambles Ltd [2004] HCA 28, courts will strictly construe sweeping indemnity clauses, particularly when they attempt to cover a party's own negligence or safety breaches. If a government water contract relies on vague, catch-all phrasing to shift liability for a specialist consultant's design failure, that ambiguity frequently renders the indemnity unenforceable against the civil contractor.

Conclusion

When a principal's demand for a 100% indemnity lands as a take-it-or-leave-it condition of award, it can feel like a commercial ultimatum you have no room to refuse. However, as this article has established, sweeping indemnities that attempt to transfer all safety, design, and defect risks are heavily restricted by Queensland statute. Broad clauses that try to bypass the proportionate liability regime, outsource strict WHS duties, or cover regulatory fines are not only commercially dangerous but, in the case of section 272A, explicitly unlawful.

Understanding the boundaries of the WHS Act, the QBCC Act, and the CLA provides the necessary leverage to push back against unreasonable risk allocation. In Queensland, section 7(3) of the CLA means a purported opt-out from proportionate liability is generally ineffective, so the statutory apportionment defence should shield you from bearing the full cost of a third-party consultant's design failure — but failing to carve out WHS penalties still exposes your firm's directors to direct regulatory prosecution.

Do not sign an unamended government indemnity on the assumption that it will be unenforceable later — with section 272A, the risk crystallises the moment you sign, not when someone tries to call on it. Before you execute anything, have the indemnity and special conditions reviewed while you still have the leverage to negotiate. Send us the indemnity clause and the special conditions from your water contract, and we will provide a fixed-scope pre-execution review — identifying the void terms, the exposure gaps against your insurance, and the specific carve-outs and caps to put into your redlines before the tender closes.

FAQs

Can an indemnity clause in a water infrastructure contract transfer WHS duties?

No. Section 272 of the Work Health and Safety Act 2011 (Qld) expressly voids any contractual term that purports to transfer a statutory safety duty to another person. A principal cannot rely on a broad indemnity to avoid their non-delegable health and safety obligations.

Is it legal to indemnify a principal against workplace safety penalties in Queensland?

No. Section 272A of the Work Health and Safety Act 2011 (Qld) makes it an offence, without reasonable excuse, to enter into, provide, or take the benefit of an arrangement that purports to indemnify a person for all or part of a monetary penalty under the Act. Contractors who agree to cover these fines may expose themselves to regulatory prosecution.

How does proportionate liability affect an indemnity clause?

In Queensland, section 31 of the Civil Liability Act 2003 limits a concurrent wrongdoer’s liability to an amount the court considers just and equitable. This statutory apportionment can frustrate absolute back-to-back indemnity claims, and because section 7(3) withholds the proportionate liability provisions from the parties' freedom of contract, a purported opt-out is generally ineffective in Queensland.

Can a civil contractor use an indemnity to avoid QBCC defect liabilities?

Not by general exclusion clauses. Section 108D of the Queensland Building and Construction Commission Act 1991 prohibits contracting out of the Act, and voids a domestic building contract to the extent it purports to annul, exclude or change a provision of the Act. Its strongest voiding limbs are framed around domestic building contracts, so contractors should first confirm whether their contract engages those provisions before relying on section 108D.

What happens if a government contract opts out of proportionate liability?

In Queensland, section 7(3) of the Civil Liability Act 2003 withholds the proportionate liability provisions from the parties' freedom of contract, so a purported opt-out is generally ineffective — Queensland is the only Australian jurisdiction that does not permit contracting out. The section 31 apportionment defence should therefore remain available even where a contract attempts to exclude it, limiting the contractor to its just and equitable share rather than 100% of an apportionable claim.

How do Queensland courts interpret ambiguous indemnity clauses?

Courts construe indemnity clauses strictly and, where they are ambiguous, against the party seeking to enforce the indemnity (a principle closely related to the contra proferentem rule). If a broad clause attempts to cover a principal's own negligence without explicit wording, a court may find it unenforceable.
