Liquidated damages play a key role in Australian contract law. LDs offer a mechanism for parties to address breaches efficiently and predictably. Whether you’re drafting a construction contract, lease agreement, or sale of goods contract, understanding the nuances of liquidated damages is essential.
This guide, written by a top contract lawyer, explores their purpose, legal framework, applications, and implications, providing valuable insights for businesses and legal practitioners alike.
Key takeaways
- Liquidated damages are pre-agreed sums to compensate for specific breaches, distinct from penalties
- They ensure cost predictability, reduce litigation, and allocate risk effectively
- Governed by common law principles, particularly the High Court decision in Andrews v ANZ Banking Group Ltd (2012)
- Commonly used in construction contracts, lease agreements, and sale of goods contracts
- Clauses must reflect a genuine pre-estimate of loss to avoid being deemed unenforceable penalties

What are liquidated damages?
Liquidated damages refer to a predetermined sum agreed upon by contracting parties to compensate for specific breaches, such as delays in performance. Unlike penalties, which aim to punish, liquidated damages are designed to estimate the actual loss suffered due to the breach.
Purpose of Liquidated Damages
- They eliminate the need for litigation to determine damages
- By quantifying breach consequences, they influence parties’ behaviour and performance incentives
- They provide financial clarity, aiding economic planning and risk assessment
Legal Framework in Australia
The enforceability of liquidated damages is governed by principles established in Australian common law.
Key Case Law
Andrews v ANZ Banking Group Ltd (2012) HCA 30
- The High Court clarified that a clause is a penalty if it imposes a detriment disproportionate to the innocent party’s legitimate interest in performance.
- A clause must represent a genuine pre-estimate of loss to be enforceable.
Paciocco v Australia and New Zealand Banking Group Ltd [2016] HCA 28
- The High Court further clarified the application of the penalty doctrine post-Andrews.
- The case examined whether late payment fees charged by a bank were penalties.
- The High Court concluded that the fees were not penalties as they were not out of proportion to the legitimate interest of the bank in receiving timely payment.
Proportionality Test
Courts will scrutinise whether the liquidated damages clause is proportionate to the potential loss. If deemed penal, the clause will be unenforceable, and standard contractual remedies will apply.
Common Applications of Liquidated Damages
1. Construction Contracts
Liquidated damages clauses are frequently used to address delays in project completion. For example, a contractor may agree to pay a specified amount per day of delay to cover the owner’s overrun costs.
2. Lease Agreements
In lease agreements, these clauses ensure landlords receive compensation for late rent payments, mitigating inconvenience and financial loss.
3. Sale of Goods Contracts
Liquidated damages may apply when a seller fails to deliver goods within the agreed timeframe. The sale of goods contract will specify the compensation to the buyer for potential losses or disruptions.
Potential Implications of Liquidated Damages
1. Risk Allocation
By explicitly quantifying breach consequences, liquidated damages clauses shift risk between parties, influencing their behaviour and performance incentives.
2. Cost Predictability
These clauses provide financial certainty, enabling parties to plan and assess risks effectively.
3. Litigation Reduction
Predefined compensation reduces the likelihood of lengthy and costly litigation to assess damages following a breach.
4. Challenges and Enforcement
The validity of liquidated damages clauses can be contested. If deemed penal, they may be unenforceable, reverting parties to standard contractual remedies.

Drafting Tips for Enforceable Liquidated Damages Clauses
- Ensure the amount reflects a reasonable estimate of potential losses
- The clause should not impose a detriment disproportionate to the breach
- Clearly define the breach and the corresponding liquidated damages amount
- Consider precedents like Andrews v ANZ Banking Group Ltd
- Engage contract legal professionals to ensure compliance with Australian contract law principles
