Why Contracts Matter in Australia
Contracts are legally binding agreements that outline the rights and obligations of the parties involved. In Australia, contracts are governed by both common law principles and statutory requirements, such as the Australian Consumer Law (ACL) and the Corporations Act 2001 (Cth).
A well-drafted contract not only protects your interests but also minimises the risk of disputes and legal challenges.

Steps to Writing a Legally Sound Contract
1. Research Thoroughly
Before drafting a contract, conduct comprehensive research to understand the legal and industry-specific context. Key steps include:
- Reviewing relevant Commonwealth and State legislation (e.g. Fair Work Act 2009 (Cth) for employment contracts)
- Consulting industry standards and guidelines
- Analysing similar contracts to identify common risks and opportunities
Helpful Resources:
- Austlii
- Commonwealth Legislation (i.e. federal laws)
- Queensland Legislation (i.e. State-based laws)
2. Choose the Right Contract Format
Selecting the appropriate format is crucial for enforceability. Common formats include:
Standard Form Contracts
- Ideal for routine transactions
- Ensure compliance with unfair contract terms laws under the ACL
Deeds
- Use when there is no consideration exchanged (e.g., one-sided promises)
- Must comply with specific execution requirements under the Corporations Act 2001 (Cth)
Master Agreements
- Suitable for ongoing relationships involving multiple transactions
- Simplifies future dealings by setting standard terms
3. Identify the Contracting Parties Correctly
Incorrectly identifying the parties can render a contract unenforceable. Ensure you:
- Use the full legal name of each party (e.g. “ABC Pty Ltd” instead of “ABC”)
- Include Australian Business Numbers (ABNs) or Australian Company Numbers (ACNs)
- Verify details through an ASIC search or ABN lookup

4. Define Key Terms Clearly
Ambiguity in definitions can lead to disputes. Follow these best practices:
- Align definitions with their usage in the contract
- Avoid including obligations or warranties within definitions
- Specify that references to legislation include amendments or replacements
Example: “Goods” means the products listed in Schedule 1, including any updates agreed upon in writing by both parties.

5. Address Risks and Dispute Resolution
Anticipate potential risks and include clauses to mitigate them. Key considerations:
- Specify dispute resolution methods (e.g. mediation, arbitration)
- Outline any liquidated damages, warranties or limitation on liability
- Include termination clauses outlining grounds for ending the agreement (such as termination for convenience)
- Address contingencies such as force majeure events
6. Outline the Contract Period
Clearly define the duration of the contract. Options include:
- Fixed-term periods with start and end dates
- Event-based durations (e.g. “until completion of services”)
- Renewal options for ongoing agreements
7. Structure and Organise Clauses Effectively
A well-organised contract is easier to read and enforce. Use a logical structure, such as:
- Parties and Recitals: Background information
- Definitions: Key terms used throughout the contract
- Operative Clauses: Rights, obligations, and conditions
- Dispute Resolution: Steps to resolve conflicts
- Termination: Grounds for ending the agreement
- Schedules: Detailed information (e.g. scope of work, pricing)
8. Write Clearly and Concisely
Avoid unnecessary complexity by:
- Using short sentences and paragraphs
- Eliminating redundant words or phrases
- Ensuring the contract is understandable to non-lawyers
9. Include a Proper Signing Clause
For companies, ensure the signing clause complies with the Corporations Act 2001 (Cth) to rely on the indoor management rule. Example:
“Executed by ABC Pty Ltd in accordance with section 127 of the Corporations Act 2001 (Cth):”
