Demand Letter for Breach of Contract (Australia)

A Demand Letter for Breach of Contract in Australia formally puts the other party on notice of a concern or claim and states what is required to resolve it, supporting later action under the Australian Consumer Law (Competition and Consumer Act 2010, Schedule 2).

The Demand Letter for Breach of Contract is central to pre-litigation dispute resolution in Australian contract law. It formally documents the breach, notifies the breaching party of the claim, provides them with a final opportunity to remedy the breach voluntarily, and creates an evidential record that the innocent party took reasonable pre-litigation steps. In all Australian jurisdictions, courts expect parties to attempt to resolve disputes before commencing litigation, and a well-drafted demand letter is the clearest demonstration of that attempt.

Breaches of contract in Australia are governed by the general law of contract — the common law as developed by Australian courts, including the High Court of Australia — and, for consumer contracts, by the Australian Consumer Law (ACL), set out in Schedule 2 to the Competition and Consumer Act 2010 (Cth). The ACL imposes mandatory consumer guarantees on supplies of goods and services that cannot be excluded by contract terms (ACL s64). These guarantees include that goods must be of acceptable quality (ACL s54), fit for any disclosed purpose (ACL s55), match their description (ACL s56), and that services must be provided with due care and skill (ACL s60).

Damages for breach of contract are assessed on the expectation measure — the aim is to put the innocent party in the position they would have been in had the contract been performed, as established in Robinson v Harman (1848) 1 Exch 850 and consistently applied by Australian courts including the High Court in Alstom Ltd v Yokogawa Australia Pty Ltd [2012] SASC 49. The innocent party must mitigate their loss by taking reasonable steps to reduce the damage caused by the breach. Consequential losses are recoverable only to the extent they were within the reasonable contemplation of both parties at the time the contract was entered into, following the principle in Hadley v Baxendale [1854] 9 Exch 341.

The limitation period for breach of contract claims in Australia is generally 6 years from the date of breach, under the applicable state Limitation Act. Issuing a demand letter well within this period is critical to preserving the innocent party's legal rights.

The legal framework governing the Demand Letter for Breach of Contract (Australia) in Australia draws on several key statutes and regulatory bodies. Under Australian law, the Privacy Act 1988 (Cth) and Australian Privacy Principles (APPs) govern personal data in this document. The Australian Consumer Law (Schedule 2, Competition and Consumer Act 2010) provides consumer guarantees under Sections 51-54. The Federal Circuit and Family Court of Australia has jurisdiction over family law matters under the Family Law Act 1975 (Cth). The Australian Financial Complaints Authority (AFCA) handles consumer financial disputes. State and territory Magistrates Courts handle small civil claims. Parties executing a Demand Letter for Breach of Contract (Australia) in Australia should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Australian Consumer Law (Competition and Consumer Act 2010, Schedule 2) sets the foundational requirements.

A demand letter for breach of contract is needed whenever one party to a contract in Australia fails to perform their obligations, and the innocent party wishes to formally demand remedy before commencing court proceedings. It is used across a wide range of commercial and personal contract disputes.

The most common scenario is a contractor or supplier who has failed to complete work or deliver goods by the agreed deadline, or who has abandoned a project mid-way through. In the construction and building industry, which is heavily litigated in Australia, a formal demand letter is an important first step before commencing proceedings in a state tribunal or court, or invoking dispute resolution procedures under the contract. The Security of Payment Acts (Building and Construction Industry Security of Payment Act 1999 (NSW) and equivalent legislation in other states) provide additional adjudication mechanisms for progress payment disputes in the construction industry.

A demand letter is also appropriate where a service provider has performed services defectively or not in accordance with the contract specifications, and has refused to remedy the defects or compensate the customer. For consumer contracts, the ACL consumer guarantee regime provides additional grounds for a claim, and a formal demand letter that references the applicable ACL guarantees strengthens the innocent party's position.

Business-to-business contract disputes — including supply agreements, distribution agreements, licensing agreements, and commercial leases — frequently give rise to demand letters where one party has failed to pay amounts due, failed to perform obligations, or purported to terminate the contract without lawful basis. In these situations, the demand letter identifies the breach, quantifies the loss, and demands a remedy within a specified period.

Personal contracts — including contracts for the purchase of goods from a private seller, home improvement contracts, and personal services contracts — also give rise to demand letters where the goods are defective, the works are incomplete, or the promised service has not been delivered. For consumer contracts at the lower end of the value scale, the demand letter is often the only step the consumer needs before lodging an application in a state tribunal (NCAT in NSW, VCAT in Victoria, QCAT in Queensland, etc.).

A demand letter is also the appropriate first step where a party has repudiated a contract — that is, indicated by words or conduct that they do not intend to be bound by their obligations. The innocent party should respond promptly, accept the repudiation, and formally demand compensation for the loss caused.

An effective Australian demand letter for breach of contract must contain several key elements to be legally sound and practically effective as a pre-litigation notice.

The letter must begin by clearly identifying both parties — the sender (innocent party) and the recipient (breaching party) — with full legal names, registered business names, ABN or ACN if applicable, and addresses. For companies, the registered office address as recorded at ASIC Connect should be used. The date of the letter is important because it starts the response period.

The contract must be precisely described — identifying its nature (supply of goods, services, lease, construction, etc.), the date it was entered into, whether it was written or oral, the key obligations of the recipient, and the agreed consideration. Where the contract is in writing, a reference number or document title should be included. The clearer the identification of the contract, the harder it is for the recipient to claim they did not understand what was demanded of them.

The specific breach must be set out with particularity. Vague claims of 'failing to perform' are far less effective than a chronological account of the specific obligations breached, the dates of relevant events, and the steps already taken by the innocent party to seek resolution. Where the breach involves a failure to meet a deadline, the agreed deadline and the actual (non-)performance should be stated. Where the breach involves defective work, the specific defects and their impact should be described.

For consumer contracts, the letter should identify the applicable ACL consumer guarantees (acceptable quality under s54, fit for purpose under s55, or due care and skill for services under s60) that have been breached, because these guarantees independently entitle the consumer to a remedy regardless of the contract terms.

The remedy demanded must be specific: either completion of the works by a specific date, payment of a specified amount representing damages or the outstanding contract price, or both. Where damages are claimed, the calculation should be set out — including the cost to engage a substitute contractor, the value of lost work, delay damages, and any other foreseeable loss. The innocent party's duty to mitigate should be noted.

The response deadline of 14 to 28 days should be reasonable in the circumstances. The consequences of non-compliance — commencing proceedings in the appropriate court or tribunal in the relevant Australian state or territory — must be stated clearly. A legal costs warning is appropriate where the amount justifies the cost of litigation.
