In an Australian business contract, an indemnity is a promise by one party to pay for the losses that the other party suffers in a defined situation. If you have ever signed a contract containing a line about "indemnifying" the other party, you have already agreed to carry some of their risk. The question is how much.
Drafted properly, an indemnity is a clean way to allocate risk: the party best placed to control a risk agrees to carry it. Drafted carelessly, it can become an open-ended promise to pay for losses you had no part in causing. This guide explains what an indemnity means in Australian law, the parts that every indemnity clause contains, how courts read them, and the misunderstandings that regularly cost small businesses money.
The building blocks of an indemnity clause
An indemnity is not an abstract legal concept that sits apart from your contract. It is a clause, and its meaning comes entirely from its wording. Every indemnity clause answers the same five questions, and the answers determine how much risk actually moves between the parties:
- Who indemnifies whom: whether the promise runs one way or both ways
- Which losses are covered: damages, legal costs, settlement amounts, fines
- Which events trigger it: breach, negligence, a third-party claim
- What limits apply: financial caps, exclusions of loss, time limits
- What procedures attach: notice obligations and who controls the defence
The core promise is usually simple. One party agrees to compensate the other for losses falling within a described category, such as losses caused by the indemnifier's breach, its infringement of intellectual property, or its negligence. Because the promise is contractual, it can be narrower or wider than the liability the law would otherwise impose. That is the point of an indemnity: it replaces the ordinary legal tests with whatever the parties have written.
Legal costs deserve special attention, because they are often the largest part of an indemnity claim. Some clauses expressly include the other party's lawyers' fees, sometimes "on a full indemnity basis". Others refer only to "loss" or "damages", and whether legal costs are covered then becomes a question of construction that can be disputed. If you are agreeing to indemnify someone, check whether the clause covers their legal costs, settlement amounts, internal management time and regulatory penalties, because a broad clause can leave you funding the other party's response from the first letter of demand.
Indemnities can operate without anyone being at fault
One feature of indemnities surprises most business owners: an indemnity does not depend on fault unless the wording says so. A clause triggered by "any loss arising out of or in connection with" your work can capture losses even where you did everything correctly, where the other party contributed to the loss, or where the loss was caused by something outside your control. This is what makes an indemnity riskier than an ordinary liability clause, which usually requires proof of negligence or breach.
Australian courts are alive to this. Indemnity clauses are construed strictly, meaning that if the wording is ambiguous, it is read against the party seeking to rely on the indemnity. The High Court stated the principle in Andar Transport Pty Ltd v Brambles Ltd (2004) 217 CLR 424, and the New South Wales Court of Appeal applied it in BI (Contracting) Pty Ltd v AW Baulderstone Holdings Pty Ltd [2007] NSWCA 173, holding that an indemnity clause is construed strictly in the context of the contract as a whole and, where ambiguous, in favour of the party giving the indemnity.
Strict construction cuts both ways in practice. If the clause is vague, a court is unlikely to stretch it to cover a loss that was not clearly in contemplation. But if the clause plainly says "any loss arising out of the services", a court will enforce those words, and a fault-free loss will still fall within them. The protection is in the drafting, not in the courts' sympathy.
An indemnity in action: the sign installer
A realistic example shows how this works. Metro Signs Pty Ltd installs a large illuminated sign for Harbourline Shopping Centre. The installation contract contains this clause: "Metro indemnifies Harbourline against all loss arising out of or in connection with the installation works."
Eight months later the sign falls and damages a parked car, and a pedestrian makes a claim against Harbourline. An investigation finds the sign fell because of a faulty bracket supplied by Harbourline's own contractor. Metro installed the sign exactly as instructed, so under ordinary negligence principles Harbourline's claim against Metro would be weak, and any damages might be apportioned between the parties.
Harbourline does not need to prove negligence, however. It points to the indemnity: the loss arose out of Metro's installation work, and the clause does not require Metro to have been at fault. Unless Metro can show the clause should be read down, it is now funding the claim, the investigation and, depending on the wording, Harbourline's legal costs. This is the moment when many business owners discover what "arising out of" actually means.
The example also shows why the other building blocks matter. If Metro had negotiated a cap tied to the fees paid under the contract, its exposure would stop at a figure it could price in. If the clause had required Harbourline to give prompt notice and let Metro control the defence, Metro could have investigated the faulty bracket itself and negotiated the pedestrian's claim before costs ran up. An indemnity is not a single sentence to be accepted or rejected; it is a bundle of choices about who carries which risk, and each choice can be negotiated.
Misconceptions that cost money
Several common assumptions about indemnities are wrong, and each one has a price tag attached:
-
An indemnity only bites when you were at fault: Not unless the wording says so. A clause tied to "to the extent caused by your negligence or breach" requires fault. A clause triggered by "any loss arising out of" does not. The trigger wording, not your conduct, decides the question.
-
An indemnity is the same as insurance: Insurance is a regulated contract under which an insurer bears specified risks in return for a premium. A contractual indemnity is a promise between two businesses, and your insurer is not automatically on the hook for it. Professional indemnity and public liability policies often exclude or limit liability that you assume by contract, which is why a significant indemnity should be reviewed alongside your policies before you sign.
-
An indemnity is the same as a warranty: A warranty is a promise that a state of affairs is true, such as a warranty that services will be provided with due care and skill. Breach of a warranty gives the other party a claim for damages. An indemnity is a promise to compensate for defined losses, and it can require payment without any breach occurring at all.
-
Any indemnity is enforceable, whatever the law says: There are hard statutory limits. Under s 64 of the Australian Consumer Law, which is Schedule 2 of the Competition and Consumer Act 2010 (Cth), a term that excludes, restricts or modifies the consumer guarantees, or liability for failing to comply with them, is void to that extent. And under s 199A of the Corporations Act 2001 (Cth), a company must not indemnify an officer against a liability owed to the company, a pecuniary penalty or compensation order, or a liability to someone else that did not arise out of good faith conduct. A company constitution or shareholders agreement cannot give directors a blanket indemnity for bad faith.
One further confusion comes from the courts themselves. When a judge orders costs "on the indemnity basis", that is a different use of the word, describing a more generous costs order, and it has nothing to do with the indemnity clause in your contract.
There is a final misconception worth naming: that an indemnity you give is always enforceable against you by a third party. Indemnities only bind the parties to the contract. A consumer who buys your product cannot rely on the indemnity you gave your supplier in the supply agreement, because they are not a party to it. What the consumer can rely on is the consumer guarantees, and those cannot be excluded by any side agreement between businesses, which is why indemnities between suppliers and retailers often sit alongside, rather than instead of, ACL obligations.
When a lawyer earns their fee on an indemnity clause
Indemnity clauses are where lawyers earn their keep twice: once when the contract is signed, and again when a claim arrives.
At the drafting and negotiation stage, a commercial lawyer will read the indemnity alongside the rest of the contract, because an indemnity is never understood in isolation. They will check the limitation of liability clause, the exclusions of loss, the scope of services and the other party's obligations to see what the indemnity adds on top. They will test whether the trigger wording is fault-based, negotiate a financial cap and a time limit, and identify whether the clause picks up legal costs, consequential loss or regulatory penalties. They will also check whether the indemnity runs up against a statutory limit such as the consumer guarantees or the officer indemnity rules in the Corporations Act.
When a claim arrives, a lawyer assesses whether the clause actually responds to the loss, whether the notice obligations have been met, who is entitled to control the defence, and whether the indemnity can be limited or resisted. Early advice at either stage is far cheaper than discovering the meaning of "arising out of" in the middle of a dispute.
The question to ask before you sign
Every indemnity clause in front of you can be reduced to one question: if this clause is triggered tomorrow, who pays, and can your business survive that payment? The most expensive mistake is assuming the answer is "only if I was at fault". Before you sign, find the trigger words and read them literally. If the clause says "to the extent caused by", you are covered for your own conduct. If it says "any loss arising out of", you have agreed to carry the risk regardless, and you should want a cap, an exclusion or a lawyer's opinion before the contract is executed.
