Overview
Contract law governs the formation, performance, and enforcement of agreements between parties. In Australia, contract law is primarily based on common law principles derived from English law, supplemented by statutory provisions such as the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010 (Cth)). A valid contract requires offer, acceptance, consideration, intention to create legal relations, and capacity. Contract law underpins virtually all commercial activity and is one of the most extensively litigated areas of Australian law.
Legal Framework
Australian contract law draws from common law principles established by English courts and developed by Australian courts. Key statutes include the Competition and Consumer Act 2010 (Cth), state Sale of Goods Acts, and the Electronic Transactions Act 1999 (Cth). The common law principles of offer and acceptance, consideration, estoppel, and contractual interpretation are central to the framework.
Key Doctrines
- •Offer and Acceptance — a contract requires a definite offer and unqualified acceptance
- •Consideration — each party must provide something of value to the other
- •Privity of Contract — only parties to a contract can enforce its terms (subject to statutory exceptions)
- •Promissory Estoppel — a party may be estopped from going back on a promise relied upon by the other party
- •Implied Terms — terms may be implied by statute, custom, or the court to give business efficacy
- •Unconscionability — contracts entered into through unconscionable conduct may be set aside
Practical Applications
Contract law applies to every commercial transaction — from employment agreements and construction contracts to technology licensing and international trade. Understanding when a binding agreement has been formed, what its terms are, and the remedies available for breach is essential for lawyers advising clients in any commercial context.
Common Misunderstandings
- •That verbal agreements are not binding — they are, but may be harder to prove
- •That consideration must be adequate — it need only be sufficient (something of value, even nominal)
- •That a 'subject to contract' clause always prevents a binding agreement
- •That damages are the only remedy for breach of contract — specific performance and injunctions are also available
