Whether you’re hiring a contractor, exploring a business partnership, or pitching a new idea to investors – protecting your confidential information is critical. That’s where a Non-Disclosure Agreement (NDA) comes in.
This guide, prepared by our contract law team, breaks down how to draft a legally binding NDA in Australia. We’ll cover essential clauses, legal requirements, practical drafting tips, and what to do if things go wrong.
Key Takeaways
NDAs are legally enforceable contracts used to protect confidential information.
A strong NDA should clearly define what is confidential and what isn’t.
To be valid under Australian law, NDAs must meet key contract principles.
Clauses should cover confidentiality scope, exclusions, duration, and dispute resolution.
Breaches can lead to legal action, including injunctions and damages.
What is a Non-Disclosure Agreement (NDA)?
An NDA is a legally binding contract between two or more parties that sets out how confidential information will be handled. It ensures that sensitive data isn’t shared without permission. NDAs are common in situations such as:
Business negotiations (mergers, partnerships, or joint ventures)
Employment relationships (protecting trade secrets or client databases)
Intellectual property discussions (disclosing inventions or concepts)

Essential Clauses in an NDA
Definition of Confidential Information
Clearly define what constitutes “confidential information.” This may include:
- Trade secrets
- Business strategies
- Financial data
- Intellectual property
- Client or supplier lists
Tip: Be specific – broad or vague definitions can lead to disputes.
Obligations of the Receiving Party
State the responsibilities of the party receiving the confidential information, such as:
- Maintaining confidentiality of the disclosed information
- Using the information solely for the agreed purpose
- Restricting access to authorised personnel only
Exclusions from Confidentiality
Outline circumstances where confidentiality obligations do not apply, such as:
- Information that is publicly available (not due to a breach of the NDA)
- Information already known to the receiving party before disclosure
- Information disclosed under legal or regulatory obligations
Permitted Disclosures
Allow for limited disclosure to:
Legal or financial advisers (who are also bound by confidentiality)
Other parties with prior written consent from the disclosing party
Duration of the Agreement
Define how long the NDA will remain in effect:
Fixed term (maybe 2 years)
Indefinitely (especially for information like trade secrets)
Dispute Resolution
Outline how conflicts will be resolved. Options include:
Private negotiation
Mediation or arbitration
Litigation in Australian courts
Governing Law and Jurisdiction
Specify that the NDA is governed by Australian law, and identify the relevant state or territory jurisdiction (such as New South Wales, Queensland, etc.).
Steps to Drafting a Legally Binding NDA in Australia
1. Identify the parties
Clearly state the names and roles of all parties involved (disclosing party and receiving party).
2. State the Purpose
Explain why the confidential information is being shared (such as product development talks).
3. Write in Clear, Plain English
Avoid legal jargon where possible. Clarity improves enforceability.
4. Meet Contract Law Requirements
Ensure the NDA meets the four pillars of a valid contract to be legally binding:
Offer
Acceptance
Consideration (something of value exchanged)
Intention to create legal relations
5. Customise to Your Situation
Each NDA should be tailored to suit your specific industry and information.
6. Seek Legal Advice
A business lawyer can ensure the agreement is watertight and compliant with Australian law.
Common Mistakes to Avoid
| Mistake | How to Avoid It |
|---|---|
| Vague definition of confidential info | Use precise terms and examples |
| Overly long duration | Ensure the time frame is reasonable |
| Forgetting dispute resolution | Include a clause to avoid future legal battles |
| Assuming verbal agreements are enough | Put everything in writing (even verbal disclosures can be included in the written NDA) |
Case Law Example: Madritsch KG & Anor v Thales Australia Ltd
In this case, the Supreme Court of Queensland found that Thales Australia Ltd breached a confidentiality agreement by using proprietary information provided by Madritsch KG and Nioa Nominees Pty Ltd. The court held that Thales misused confidential information related to a technological solution for a service rifle used by the Australian Defence Force, leading to a breach of the agreed NDA.

Yes, an NDA can cover verbal disclosures if explicitly stated in the agreement. However, it is advisable to document such disclosures in writing for clarity and evidence.
What happens if someone breaches an NDA?
If an NDA is breached, the disclosing party may seek legal remedies such as injunctions to prevent further disclosure or damages for any losses incurred.
How long should an NDA last?
The duration of an NDA depends on the nature of the confidential information. For example, trade secrets may require indefinite protection, while other information may only need protection for a fixed period.
