Repudiation of contract is a key principle in Australian contract law. It occurs when one party, through their words or actions, demonstrates that they no longer intend to fulfil their contractual obligations. Contract repudiation often arises in business disputes, commercial lease disagreements, and construction contract breakdowns.
In this article, our contract law team focuses on the signs of repudiation, outlines legal remedies, and offers real-world examples to help Australian businesses and individuals respond with confidence and clarity.
Key Takeaways
Repudiation occurs when one party shows (through words or actions) that they no longer intend to be bound by the contract.
The test is objective: would a reasonable person think the party has renounced their essential obligations?
Common signs include refusal to perform, imposing new conditions, making performance impossible, repeated serious breaches, or evasive behaviour.
Only serious conduct that goes to the root of the contract amounts to repudiation – not minor breaches.
Legal remedies include terminating the contract, claiming damages, or seeking specific performance.
The Australian Consumer Law may apply if misleading or deceptive conduct is involved.

What is Repudiation in Australian Contract Law?
Repudiation occurs when one party clearly indicates that they will not (or cannot) perform their contractual obligations. This can be shown through:
Direct statements, or
Conduct that implies the party no longer considers themselves bound by the agreement.
Repudiation is a common law principle, developed through court decisions rather than legislation. It plays a key role in managing risk across a wide range of commercial contracts, leases, and employment agreements.

Key Signs of Repudiation
Identifying repudiation early is essential to protect your contractual rights. Here are the most common indicators recognised by Australian courts:
1. Express Statement of Refusal to Perform
A clear verbal or written statement that the party will not perform their contractual obligations.
Example: A supplier emails stating they will not deliver goods under a purchase agreement.
2. Imposing New, Unauthorised Conditions
Demanding extra conditions that were never agreed to in the original contract.
Example: A landlord insists on an additional security deposit not mentioned in the lease.
3. Making Performance Impossible
Conduct that makes fulfilling the contract unworkable.
Common scenarios:
Going into insolvency
Damaging or destroying critical assets
Loss of necessary licences
Incapacitation (Koompahtoo Local Aboriginal Land Council v Sanpine Pty Ltd (2007))
In some cases, these situations may be covered by a force majeure clause so its important to check your contract terms.
4. Persistent Breach or Anticipatory Refusal
Repeated failure to meet obligations, or clear signs that future performance is unlikely.
Example: A builder consistently misses deadlines and warns they won’t meet the completion date.
6. Evasive or Ambiguous Conduct
Avoiding communication, refusing to confirm performance timelines, or dodging obligations.
Example: A contractor won’t commit to a delivery date and ignores repeated emails.
If you’re dealing with repudiatory conduct, understanding your rights around termination is essential. Learn more about how to legally terminate a contract in Australia.

Case Study: Repudiation in Action
Scenario:
A commercial tenant repeatedly pays rent late. After warnings, the tenant states in writing they will only continue paying if the landlord agrees to a 50% reduction.
Analysis:
The combination of repeated non-payment and the demand for new conditions would likely be viewed as repudiation by a reasonable person. The landlord may:
Accept the repudiation
Terminate the lease
Claim damages for lost rent

Frequently Asked Questions
What is the difference between a minor breach and repudiation?
Not all contract breaches amount to repudiation!
A minor breach occurs when a party fails to meet a non-essential term of the contract. This may entitle the other party to claim damages, but not usually the right to terminate the contract.
In contrast, repudiation involves a serious or fundamental breach that goes to the core of the agreement (indicating the party no longer intends to be bound by the contract).
As reaffirmed by the High Court in Koompahtoo Local Aboriginal Land Council v Sanpine Pty Ltd, repudiation requires conduct that goes to the root of the contract and undermines its central purpose.
How do I prove repudiation in Australia?
You must show that a reasonable person would believe the other party no longer intends to be bound by the contract, based on their words or conduct.
Can I terminate a contract immediately if I suspect repudiation?
You should only terminate if there is clear evidence of repudiation. Wrongful termination may expose you to liability for breach.
What remedies are available if a contract is repudiated?
Remedies include accepting the repudiation, terminating the contract, and claiming damages. Statutory remedies under the Australian Consumer Law may also apply.
Does Australian Consumer Law apply to repudiation cases?
Yes, if the repudiatory conduct also amounts to misleading or deceptive conduct or involves false representations, statutory protections under the ACL may be available.
Using clearly drafted and balanced agreements is key to avoiding disputes, this includes identifying and avoiding unfair contract terms that could lead to a breakdown in obligations.
