A breach of contract happens when one party doesn’t do what the contract requires. They might not perform at all, perform late, perform badly, or make it clear they won’t perform in future. In Australia, a breach of contract opens the door to remedies like damages, termination, specific performance or an injunction, but only where you have a legally binding agreement sitting behind the promise.
Here’s the bit nobody tells you. When a contract gets broken, most people freeze. They assume it means court, lawyers and a bill they can’t afford, so they do nothing and hope it sorts itself out. It rarely does. The good news: you usually have several cheaper, faster moves before litigation is anywhere near the table.
- A breach of contract is any failure to perform an agreed obligation without a lawful excuse. That covers non-payment, late delivery, shoddy work, or refusing to perform.
- Your remedy depends on how serious the breach is. A minor slip rarely lets you walk away; a breach of an essential term or a clear repudiation usually does.
- Start cheap, escalate only if you have to. A conversation, then a notice or letter of demand, settles most disputes long before court.
- You have a deadline. In most states you get six years from the date of breach to sue (three years in the Northern Territory).
- You must try to limit your own losses. Australian law expects the wronged party to take reasonable steps to mitigate, or the claim shrinks.
What counts as a breach of contract?
Breaking a contract means failing to perform a contractual obligation without a lawful excuse. The promise can be written, verbal, or implied by conduct. What matters is whether a binding agreement existed and whether someone fell short of it.
Not every shortfall is equal, and the difference decides what you can do next. A late invoice and a supplier who never shows up are both breaches, but only one of them lets you tear up the contract. Here are the four patterns we see most.
Material (or fundamental) breach
This is the serious one. A material breach goes to the heart of the deal, so the wronged party can usually terminate and claim damages. Think of a fit-out company you paid to install commercial kitchen equipment by a fixed opening date, who installs nothing. The whole point of the contract has failed.
Minor breach
Minor breaches are smaller failures that don’t undermine the contract’s core purpose. Say a contractor finishes the job to spec but leaves a fortnight late, and the delay cost you nothing. You can claim for any real loss, but you generally can’t walk away from the whole agreement over it.
Anticipatory breach (repudiation)
Sometimes a party tells you, by words or behaviour, that they won’t be performing before the due date even arrives. That’s an anticipatory breach, also called repudiation. A renovator who takes your deposit, goes quiet, then quietly enters liquidation has repudiated the contract.
Repudiation hands you a choice, and it’s a real fork in the road. You can accept the repudiation, end the contract and sue for your losses. Or you can affirm the contract and hold them to it. Pick wrong and you can end up the one in breach, so this is the moment to get advice rather than fire off an angry email.
Substantial performance
This one trips people up. Where a contract is almost fully performed and only a tiny bit is left undone, the shortfall is usually treated as a minor breach. A painter who does your whole office but misses a patch on one ceiling has substantially performed. You still have to pay, though you can knock off the cost of fixing the patch.
One warning from our consultations: people love to seize on substantial performance to justify withholding the entire payment. That backfires. Refuse to pay a near-complete job and you can flip yourself into the breaching party.

What happens when a contract is breached? Your remedy options
When a breach of contract is proven, Australian law offers a toolkit of remedies. Money is the most common, but it isn’t the only option. Your contract’s wording shapes what’s realistically on the table, so read it before you decide what to chase.
| Remedy | What it does | When it fits |
|---|---|---|
| Damages | Money to put you where you’d have been if the contract was performed | The default remedy for most breaches |
| Termination | Ending the contract, usually with damages for losses to date | Material breach, repudiation, or where a termination clause allows it |
| Specific performance | A court order forcing the other side to actually do what they promised | Rare, used where money won’t fix it (for example, a one-of-a-kind asset) |
| Injunction | A court order to stop doing something, or to start doing something | Ongoing breaches, like someone ignoring a confidentiality clause |
| Set-off or price adjustment | Reducing what you pay to account for defects | Where your contract allows it and the breach is partial |
Damages: the types you can claim
Damages aren’t there to punish the other side. The aim is to put you in the position you’d have been in if the breach of contract had never happened. Courts split them into a few buckets, and a single claim often combines several.
- Expectation damages. The direct loss from not getting what you were promised. Paid $12,000 for a delivery van you never received? That’s the starting figure.
- Reliance damages. Money you spent getting ready for a contract that then fell over, like hiring staff or buying stock for a launch that never happened.
- Damages for lost opportunity. Compensation for a genuine chance the breach cost you. Harder to prove, since you must show the opportunity was more likely than not to come off.
- Liquidated damages. A figure the parties agreed in the contract up front. Courts enforce it if it’s a genuine pre-estimate of loss, not a penalty dressed up as compensation.
- Nominal damages. A token amount where a breach happened but you can’t prove any real loss. It marks the wrong without a meaningful payout.
There’s a catch most people miss. You have a duty to mitigate, which means taking reasonable steps to keep your losses down. If a supplier lets you down, you’re expected to find a replacement at a fair price rather than sit back and watch the damage pile up. Sit on your hands and a court will trim what you can recover.
Specific performance and injunctions
Sometimes money won’t fix it. Specific performance is a court order making the breaching party keep their promise. It’s reserved for cases where damages fall short, classically the sale of a unique property or a rare asset. Courts won’t order it where damages would do, where the obligations are unclear, or where it would force two parties to keep working together.
An injunction is the stop sign. A court can order someone to stop breaching (a prohibitory injunction) or, less often, to take a specific action (a mandatory injunction). If a former contractor starts poaching your clients in breach of a non-compete or confidentiality clause, an injunction is how you switch that off fast.
What should you do first if someone breaches a contract?
The instinct is to threaten court on day one. Resist it. Litigation is slow, expensive and stressful, and most breaches resolve well short of a courtroom. Work through these steps in order.
1. Read the contract and gather your evidence
Before you do anything, pin down exactly what was promised. Pull the contract, the emails, the invoices, the messages, and any photos or records of what happened. Check for notice and cure clauses too, because many contracts spell out a process you must follow before you can terminate. Skip it and you weaken your own position.
2. Talk to the other party
Plenty of breaches come down to a misunderstanding, a cash-flow wobble, or a missed email. A quick conversation can sort it in a day. When you eventually speak to a lawyer, one of the first things they’ll ask is whether you’ve raised it with the other side, so get that on the record first.
3. Send a formal notice or letter of demand
If a chat doesn’t land, put it in writing. The right document depends on the breach. To formally call out the breach and demand it be fixed, a Notice to Remedy Breach of Contract sets out the problem and the time frame to put it right.
Chasing money instead? Start with a Letter of Demand, then a second and final attempt if they ignore you. Want them to stop doing something, like using your confidential information? A Cease and Desist Letter does that job. Each one creates a paper trail that matters if the dispute escalates.
4. Negotiate and lock in the deal
Most disputes end in an agreed fix: a discount, a payment plan, revised scope, or a clean exit. When you reach terms, get them in writing. A deed of settlement makes the agreement binding and releases both sides from further claims, so the matter is actually closed rather than simmering.
5. Escalate: mediation, then court
If negotiation stalls, check your contract for a dispute resolution clause. Many require good-faith talks or mediation before anyone files. Mediation is faster and far cheaper than litigation, and it works more often than people expect. Court is the last resort, and for smaller amounts your state’s small claims tribunal handles the claim without the full cost of a higher court.
How do you prove a breach of contract?
To win a breach of contract claim, you need to establish three things: a valid contract existed, a term was breached, and the breach caused you a loss. Miss any one and the claim struggles.
The “valid contract” part catches people out. A binding agreement needs offer and acceptance, consideration, an intention to create legal relations, capacity, and certainty about the terms. Without all five, there’s no contract to breach in the first place, which is why a vague verbal arrangement is so much harder to enforce than a signed document.
Watch the trap at the other end too. Withholding payment, terminating early, or downing tools because you think the other side breached can put you in breach if you’ve read the situation wrong. Reserve your rights in writing while you sort it out, and don’t accept late performance without comment, because quietly carrying on can waive the very rights you want to rely on.
How long do you have to sue for breach of contract?
You don’t get forever. Each state and territory sets a limitation period, and miss it and the other side can have your breach of contract claim thrown out no matter how strong it is. The clock starts on the date of the breach, not the day you discovered it or finally lost patience.
| Type of contract | Time limit to sue |
|---|---|
| Simple contract (most business deals) | 6 years from the date of breach, in every state except the NT |
| Simple contract in the Northern Territory | 3 years from the date of breach |
| Contract signed as a deed | Longer, commonly 12 years (15 years in Victoria and South Australia) |
In New South Wales, for example, the six-year window comes from the Limitation Act 1969 (NSW). One detail worth knowing: where a customer misses a string of monthly payments, each missed payment can be its own breach with its own six-year clock. Accurate, dated records are what let you chase the ones still in time.
Can you exit a contract without breaching it?
Yes, and this is where a lot of stress is avoidable. Walking away isn’t automatically a breach. There are three clean ways out.
By agreement. If both sides agree to end the contract early, it simply ends. Put the agreement in writing so a future dispute can’t reopen it.
Under a termination clause. Most well-drafted contracts say how either party can exit, usually with notice. Follow the clause to the letter, including the notice period and method, or your tidy exit becomes a breach.
By frustration. A contract can end through frustration when something outside both parties’ control makes performance impossible. A venue that burns down before a booked event is the textbook case. Frustration is narrow, though. A deal simply becoming more expensive or less convenient won’t cut it.
Watch out for unfair contract terms
Here’s something that changed the game and many businesses still haven’t caught up on. Since 9 November 2023, it’s against the law to propose, use, or rely on an unfair term in a standard form contract with a consumer or small business. A court can declare the term void, and now it can also hand down serious penalties.
Two things make this matter for a breach of contract dispute. First, the net is wider: the protections now cover any business with fewer than 100 employees or under $10 million in annual turnover, so far more small contracts are caught. Second, if the term the other side is leaning on is unfair, it might not be enforceable at all. Before you accept that a one-sided clause binds you, it’s worth checking whether it would survive.
What Lawpath lawyers see go wrong
Patterns repeat across our consultations. These are the ones that cost small businesses the most, and they rarely show up on a generic legal explainer.
The tiny technical breach used as a weapon. We regularly see one party seize on a small slip, an unpaid nominal fee, a missed formality, to argue the other side breached first and walk away from the whole deal. It often surfaces in shareholder and partnership disputes. The fix is usually a calm letter of demand setting out the facts, not a panicked rush to litigation.
Termination clauses that don’t separate the two situations. A common drafting fix our lawyers make is to split termination into two triggers: a longer notice period of around 28 to 30 days for ending a deal for convenience, and a short fuse for material breach so you can exit fast when the other side seriously drops the ball. Bolt a mediation step on before anyone can run to court, and most disputes never get there.
Fear of cost driving the wrong move. The pattern we see again and again: a stressed founder assumes a breach means an expensive court fight, so they either do nothing or overreact. Both make it worse. In practice the ladder of a conversation, a letter of demand, then a deed of settlement resolves the large majority of matters at a fraction of the cost and time.
Frequently asked questions
What is considered a breach of contract?
A breach of contract is when one party fails to perform an obligation under a valid contract without a lawful excuse. That includes not delivering, delivering late, doing the work poorly, not paying, or refusing to perform at all.
What is a material breach of contract?
A material breach, sometimes called a fundamental breach, is one that goes to the heart of the contract. Because it defeats the main purpose of the deal, the wronged party can usually terminate the contract and claim damages, rather than just seek a small adjustment.
Can a signed contract be broken?
Yes. A signed contract can be ended by agreement, under a termination clause, or through frustration, none of which is a breach. It can also be broken by one party failing to perform, which is a breach and may trigger remedies for the other side.
Can I sue for breach of contract if I didn’t lose money?
You can, but the payout may be small. Where a breach happened but caused no real loss, a court can award nominal damages, a token sum that recognises your rights were infringed. Most worthwhile claims need a provable loss behind them.
My contract wasn’t in writing. Can I still claim?
Possibly. A verbal agreement can be binding if it has offer and acceptance, consideration, an intention to create legal relations, capacity, and certainty. The hard part is proof, since there’s no signed document to point to.
How long do I have to sue for breach of contract?
In most Australian states you have six years from the date of the breach. The Northern Territory is the exception at three years. Contracts signed as deeds run longer, commonly 12 years, and 15 years in Victoria and South Australia.
What’s the first thing I should do about a breach?
Read the contract and gather your evidence, then raise it directly with the other party. A conversation resolves a lot of breaches. If that fails, a written notice or letter of demand is the next step, well before you think about court.
What is it called when you break a contract?
Breaking a contract is called a breach of contract, or breaching the contract. If a party makes clear they won’t perform before performance is due, that specific kind is called anticipatory breach or repudiation.
The one thing to do next
If a contract has been broken on you, you’re not behind and you haven’t blown it. This is ordinary stuff for a running business, and you have more options than the worst-case scenario in your head. Start with the cheapest move that fits, and only climb the ladder if you have to.
The fastest way to put the other side on notice and protect your position is to get it in writing today. Create your Notice to Remedy Breach of Contract on Lawpath in minutes, and have your demand documented before the day’s out.
