What is a Breach of Contract? Understanding Your Rights and Remedies in Queensland

Published by Odyssey Legal | Business & Litigation Lawyers

You performed your obligations under the contract exactly as agreed. You delivered the goods on time, completed the work to specification, paid the deposit when required, or provided the services as promised. But the other party has failed to hold up their end of the bargain. They have not paid you, have not delivered what they promised, have performed work so poorly it is worthless, or have simply walked away from their obligations entirely.

This is a breach of contract, and it is one of the most common disputes in business and commercial transactions. A breach of contract occurs when one party fails to perform their contractual obligations without lawful excuse, whether through complete non-performance, defective performance, or refusal to perform.

For Queensland business owners and individuals who have been let down by parties who failed to honour their agreements, understanding what constitutes a breach of contract, what types of breaches exist, what remedies are available, how damages are calculated, and when you can terminate a contract can mean the difference between recovering your losses and absorbing significant financial harm.

Within this article, our expert litigation lawyers, will breakdown how a breach of contract occurs and why it is crucial to obtain advice. Alternatively, watch our Youtube Video breaking it down (click here).

What is a Breach of Contract?

A breach of contract occurs when a party to a contract fails to perform one or more of their obligations under the agreement without lawful excuse or justification. The breach can be total, where the party does not perform at all, or partial, where some obligations are performed but others are not or are performed defectively.

For a breach to give rise to legal remedies, several elements must be established.

First, a valid contract must exist containing the essential elements of offer, acceptance, consideration, and intention to create legal relations.

Second, the contract must impose obligations on the party alleged to have breached.

Third, that party must have failed to perform those obligations without lawful excuse such as the contract being frustrated, discharged, or performance being excused by the other party's conduct.

Fourth, the breach must have caused loss or damage to the innocent party.

Breach of contract is fundamentally different from simply being unhappy with a transaction or regretting entering into an agreement. A breach requires that specific contractual obligations were not performed, not merely that the outcome was disappointing or that you would prefer different terms in hindsight.

Types of Breach of Contract

Breaches of contract can take various forms, and understanding what type of breach has occurred affects what remedies are available.

Non-Performance or Complete Failure to Perform

Non-performance occurs when a party simply does not do what they contracted to do at all. This is the most straightforward type of breach. Common examples include a supplier who takes payment but never delivers the goods ordered, a contractor who never commences work after receiving a deposit, a buyer who refuses to pay for goods or services provided, or a party who walks away from the contract entirely without performing.

Complete non-performance is typically a serious breach giving rise to the right to terminate the contract and claim substantial damages, as the innocent party receives no benefit whatsoever from the agreement.

Late Performance or Delay

Late performance occurs when obligations are performed but not within the timeframe specified in the contract. Whether delay constitutes a breach depends on whether time was of the essence in the contract. If the contract explicitly states that time is of the essence or if the nature of the contract makes timing critical, then any delay is a breach. If time is not of the essence, then only unreasonable delay that causes loss constitutes a breach.

Examples include a supplier delivering goods two months late when the contract specified delivery within four weeks, a builder completing construction six months after the agreed completion date, or a professional providing advice after the deadline when the advice was needed for a time-sensitive decision.

Late performance can be a serious breach if time was essential or if the delay causes significant loss. However, if the delay is minor and causes no real loss, remedies may be limited or nominal.

Defective Performance or Poor Quality

Defective performance occurs when the party does perform but the performance fails to meet the standards, specifications, or quality required by the contract. The work is done, but it is done poorly, incorrectly, or to a standard below what was agreed.

Common examples include a builder completing construction but with workmanship that does not meet building codes or contract specifications, a manufacturer delivering goods that do not meet the agreed specifications or are defective, a service provider performing services that are substandard or do not achieve the contracted outcome, or a professional providing advice that is incorrect, incomplete, or negligent.

Defective performance can be remedied through damages calculated as the cost of rectifying the defects, the difference in value between what was promised and what was delivered, or consequential losses caused by the defective performance.

Anticipatory Breach or Repudiation

Anticipatory breach, also called repudiation, occurs when one party indicates before the time for performance that they will not perform their obligations. This can happen through explicit statements that they will not perform or through conduct that clearly shows they do not intend to perform.

Examples include a buyer telling a supplier before the delivery date that they will not accept or pay for the goods, a contractor announcing they are abandoning a project before completion, or a party's conduct making it impossible for them to perform such as selling goods to another buyer that they were contractually obligated to deliver to you.

Anticipatory breach gives the innocent party the option to either accept the repudiation and immediately claim damages without waiting for the performance date, or affirm the contract and wait until the performance date to see if the breaching party changes their mind and performs.

Material Breach vs. Minor Breach

Not all breaches are equal in seriousness or consequences. Contract law distinguishes between material breaches and minor breaches, with significant implications for remedies.

A material breach, also called a fundamental breach, is a serious breach of an essential term (called a condition) that goes to the heart of the contract and deprives the innocent party of substantially the whole benefit they were to receive. Material breaches give the innocent party the right to terminate the contract, refuse to perform their own remaining obligations, and claim damages for all losses caused by the breach.

Examples of material breach include a builder abandoning a construction project halfway through, a supplier delivering completely different goods than what was ordered, or a party refusing to perform the core obligation that was the entire purpose of the contract.

A minor breach, also called a breach of warranty, is a breach of a less important term that does not go to the root of the contract. While the innocent party can claim damages for losses caused by the minor breach, they cannot terminate the contract and must continue to perform their own obligations.

Examples of minor breach include slight delays that cause no real loss, minor defects that can be easily and inexpensively remedied, or breaches of ancillary terms that do not affect the main purpose of the contract.

The distinction between material and minor breach is crucial because it determines whether you can walk away from the contract or must continue to perform while claiming damages for the breach.

Remedies for Breach of Contract

When a contract is breached, the innocent party has various potential remedies depending on the type and seriousness of the breach.

Damages

Damages are monetary compensation awarded to put the innocent party in the position they would have been in if the contract had been performed properly. This is the most common remedy for breach of contract and is available for all types of breaches.

Damages aim to compensate for actual losses suffered, not to punish the breaching party. To recover damages, you must prove that you suffered actual loss as a result of the breach, that the loss was caused by the breach, that the loss was reasonably foreseeable at the time the contract was made, and that you took reasonable steps to mitigate or minimise your losses.

Common types of damages include direct losses such as the cost of obtaining substitute performance from another supplier, wasted expenditure incurred in reliance on the contract, loss of profit that would have been earned if the contract was performed, and consequential losses such as loss of business opportunities or damage to reputation caused by the breach.

The burden is on the innocent party to prove their losses with evidence. Vague claims of loss without supporting documentation will not succeed. Detailed financial records, invoices, contracts with alternative suppliers, and expert evidence may be necessary to establish the quantum of damages.

Termination

For material breaches of essential terms (conditions), the innocent party has the right to terminate the contract. Termination means you are released from performing your own remaining obligations and can treat the contract as at an end, while still claiming damages for losses caused by the breach.

Termination is a significant step with serious legal consequences. If you terminate when you are not legally entitled to do so because the breach was not sufficiently serious, you yourself commit a breach and may face damages claims from the other party. Before terminating, you should seek legal advice to ensure the breach is serious enough to justify termination.

Termination is typically appropriate when the other party has completely failed to perform, has performed so defectively that the performance is worthless, has repudiated the contract by indicating they will not perform, or has breached an essential term that goes to the heart of the contract.

Specific Performance

Specific performance is a court order requiring the breaching party to actually perform their contractual obligations. It is an equitable remedy that is only available in limited circumstances, typically where damages would be an inadequate remedy and the subject matter of the contract is unique.

Specific performance is most commonly ordered for contracts involving the sale of land, as each piece of land is considered unique and damages cannot adequately compensate for its loss. It is rarely ordered for contracts for services, as courts are reluctant to force people to work or provide services against their will. It is generally not available for contracts that would require ongoing court supervision to ensure compliance.

Specific performance is an exceptional remedy reserved for special circumstances. In most breach of contract cases, damages are the appropriate and only available remedy.

Injunctions

An injunction is a court order requiring someone to do something or to stop doing something. In contract law, injunctions can be used to enforce negative obligations such as restraint of trade clauses or non-compete agreements where damages would be inadequate.

For example, if an employee breaches a non-compete clause by working for a direct competitor in breach of their employment contract, an injunction can order them to stop working for the competitor. Injunctions are also used to prevent breaches of confidentiality obligations or to stop a party from acting in a way that would breach the contract.

Injunctions can be interim, granted on an urgent basis until trial, or permanent, granted after a full hearing. To obtain an injunction, you must typically show that damages would not adequately compensate you for the breach and that the balance of convenience favours granting the injunction.

Calculating Damages for Breach of Contract

Calculating the appropriate amount of damages in breach of contract cases requires understanding several legal principles that govern how losses are measured and what can be recovered.

The fundamental principle is that damages aim to put the innocent party in the position they would have been in if the contract had been performed, not to punish the breaching party or put the innocent party in a better position than performance would have achieved.

The expectation measure calculates what benefit you expected to receive from the contract and compensates you for not receiving that benefit. For example, if you contracted to buy goods for fifty thousand dollars that you intended to resell for seventy thousand dollars, and the supplier breaches by not delivering, your expectation loss is the twenty thousand dollar profit you would have made.

The reliance measure calculates what you spent in reliance on the contract that is now wasted due to the breach. For example, if you paid a ten thousand dollar deposit and incurred five thousand dollars in preparation costs before the other party breached, your reliance loss is fifteen thousand dollars.

Damages must be caused by the breach, meaning you must prove a direct causal link between the breach and your loss. Losses that would have occurred anyway even if the contract had been performed are not recoverable.

Damages must be reasonably foreseeable, meaning they must be losses that arise naturally from the breach or that were within the contemplation of both parties at the time the contract was made as a probable result of breach. Unusual or unexpected losses that neither party anticipated are generally not recoverable.

You have a duty to mitigate your losses by taking reasonable steps to minimise the damage caused by the breach. For example, if a supplier breaches by not delivering goods, you should attempt to source the goods elsewhere if possible. If you fail to mitigate and your losses are therefore higher than necessary, the excess may not be recoverable.

Common Defences to Breach of Contract Claims

When accused of breach of contract, parties often raise defences that, if successful, can reduce or eliminate liability.

A common defence is that the contract was not validly formed because one or more essential elements were missing, the contract fails for uncertainty because essential terms were never agreed, or the contract is unenforceable due to lack of written documentation where required by law.

Another defence is that the contract has been discharged or ended such that obligations no longer apply, through frustration where unforeseen events made performance impossible or radically different from what was contemplated, through mutual agreement where both parties agreed to end the contract, or through performance where all obligations have been completed.

Defendants may claim the breach was caused or contributed to by the plaintiff's own conduct, such as the plaintiff preventing or hindering performance, failing to perform their own obligations first where performance was conditional, or accepting defective performance without objection, which may constitute waiver.

Some defendants argue damages should be reduced or eliminated because the plaintiff failed to mitigate their losses by taking reasonable steps to minimise damage, the plaintiff's losses were not reasonably foreseeable at the time the contract was made, or the losses claimed were not actually caused by the breach but by other factors.

Time Limits for Breach of Contract Claims

Breach of contract claims in Queensland are subject to limitation periods under the Limitation of Actions Act 1974. Generally, you have six years from the date of breach to commence court proceedings. This means if someone breaches a contract, you have six years from when the breach occurred to file your claim in court.

The limitation period is strict. If you do not commence proceedings within six years, your claim becomes statute-barred and you lose your right to sue permanently, even if you have a valid claim and clear evidence of breach and losses.

The six-year period generally starts from when the breach occurred, not from when you discovered the breach or realised you had a claim. This means the clock starts ticking immediately when the breach happens, whether you are aware of it or not.

There are limited exceptions where limitation periods can be extended, such as where fraud concealed the breach or where the defendant acknowledged the debt or claim in writing. However, these exceptions are narrow and uncertain, so you should never rely on them.

If a contract has been breached, seek legal advice promptly and do not delay in pursuing your claim. Waiting until you are approaching the six-year deadline significantly limits your options and increases the risk of losing your right to claim entirely.

Frequently Asked Questions About Breach of Contract

What is the difference between a material breach and a minor breach?

A material breach, also called a fundamental breach, is a serious breach of an essential term that goes to the heart of the contract and deprives you of substantially the whole benefit you were to receive. Material breaches give you the right to terminate the contract and claim damages. Examples include complete non-performance, repudiation, or defective performance that makes the contract worthless. A minor breach is a breach of a less important term that does not go to the root of the contract. You can claim damages for losses caused by minor breaches, but you cannot terminate the contract and must continue performing your own obligations. The distinction is critical because it determines whether you can walk away from the contract or must continue to perform.

How much can I claim in damages for breach of contract?

You can claim damages that put you in the position you would have been in if the contract had been performed properly. This includes direct losses such as the cost of obtaining substitute performance from another supplier or contractor, wasted expenditure you incurred in reliance on the contract, lost profits you would have earned if the contract was performed, and consequential losses such as lost business opportunities that were reasonably foreseeable. However, you must prove your losses with evidence, the losses must have been caused by the breach, they must have been reasonably foreseeable when the contract was made, and you must have taken reasonable steps to mitigate or minimise your losses. You cannot claim damages to punish the breaching party or put yourself in a better position than performance would have achieved.

Can I terminate a contract if the other party breaches?

You can only terminate a contract if the breach is sufficiently serious, specifically, if it is a material breach of an essential term (called a condition) that goes to the heart of the contract. Minor breaches of less important terms (called warranties) do not give you the right to terminate, though you can claim damages for losses caused. Terminating when you are not entitled to do so because the breach was not serious enough makes you the breaching party and exposes you to damages claims. Before terminating, you should seek legal advice to ensure the breach justifies termination. If termination is justified, you should also give clear written notice of termination to avoid disputes about whether the contract was actually ended.

What should I do if someone breaches a contract with me?

First, review the contract carefully to confirm that a breach has actually occurred and what your rights and remedies are under the contract terms. Gather all evidence documenting the breach including correspondence, invoices, photographs, or other proof. Send a formal written notice to the breaching party identifying the breach and requiring them to remedy it within a reasonable timeframe, often seven to fourteen days. This notice preserves your rights and may prompt compliance without litigation. If they do not remedy the breach, seek legal advice about your options including claiming damages, terminating the contract if the breach is serious enough, or commencing court proceedings. Do not delay, as you have a duty to mitigate your losses and limitation periods may be running.

Do I need to give notice before terminating a contract for breach?

While there is no absolute legal requirement to give notice before terminating for a material breach, it is generally advisable to do so for several reasons. First, giving notice and an opportunity to remedy the breach demonstrates you acted reasonably, which courts look favourably upon if proceedings follow. Second, some contracts explicitly require notice before termination, and failing to give notice could make your termination wrongful. Third, notice creates a clear record of when and why you terminated, avoiding disputes about whether termination actually occurred. Fourth, the breaching party may remedy the breach after receiving notice, resolving the matter without termination. A notice of breach and intention to terminate should identify the specific breach, require remedy within a reasonable timeframe, and state that failure to remedy will result in termination.

How long do I have to sue for breach of contract in Queensland?

In Queensland, the limitation period for breach of contract claims is six years from the date the breach occurred under the Limitation of Actions Act 1974. This is a strict deadline. If you do not commence court proceedings within six years of the breach, you lose your right to sue permanently even if you have a valid claim. The six-year period generally starts when the breach occurred, not when you discovered it or realised you had a claim. There are very limited exceptions where limitation periods can be extended, such as fraud concealing the breach or written acknowledgment of the debt by the defendant, but these are narrow and you should not rely on them. If a contract has been breached, seek legal advice promptly and do not delay pursuing your claim.

Can I claim damages if I did not suffer any financial loss from the breach?

If you suffered no actual financial loss from a breach of contract, you can still sue for breach but your damages will likely be nominal, typically a small amount like one dollar or one hundred dollars acknowledging the breach occurred but you suffered no real loss. Contract damages aim to compensate actual losses, not to punish breaches where no harm resulted. However, in some circumstances you may recover damages even without immediate financial loss, such as where the breach causes loss of opportunity that cannot be precisely quantified but clearly has value, where you are entitled to the cost of reinstatement or rectifying defects even if you have not yet incurred that cost, or where the contract provides for liquidated damages (a pre-agreed amount) upon breach regardless of actual loss suffered.

What happens if both parties have breached the contract?

If both parties have breached the contract, each party may have claims against the other, and the outcome depends on the seriousness and timing of each breach. Courts will assess which party committed the first or more serious breach, whether one party's breach excused the other's non-performance, and what losses each party suffered as a result of the other's breach. In many cases where both parties have breached, the claims are offset against each other and the party who suffered greater net loss recovers the difference. However, if you have breached the contract yourself, this may limit your ability to terminate or claim damages for the other party's breach, depending on whether your breach came first or was itself a response to their breach. These situations are complex and require careful legal analysis of the sequence of events and the seriousness of each breach.
