Core Difference: Purpose
NDA (Non-Disclosure Agreement): Protects information. Its sole purpose is to establish that certain information is confidential and must be kept secret. An NDA doesn't define the work itself.
Contractor Agreement: Defines the working relationship. It specifies what work will be done, how much it costs, payment terms, deadlines, IP ownership, and other terms of engagement.
When to Use Each Agreement
Use an NDA if:
- You're sharing an idea or business plan with a potential partner or investor
- You're discussing a merger or acquisition
- You want to pitch a product concept before a full agreement is signed
- Someone needs access to confidential information but no work is being performed yet
Use a Contractor Agreement if:
- Someone is doing paid work for you (designing, coding, writing, etc.)
- You're hiring someone for a project or ongoing services
- You need to specify deliverables, payment, and deadlines
- You want to establish IP ownership of the work
Should You Use Both?
Yes, often. When hiring a contractor who will access confidential information, you should use both:
Contractor Agreement covers: work scope, payment, deliverables, deadlines, IP ownership
NDA covers: confidentiality of your business information they'll access during the work
The Contractor Agreement handles the engagement; the NDA protects your secrets.

Real-World Scenarios and Which Document to Use
Scenario 1: Pitch Meeting
You're pitching your app idea to a potential investor. Use an NDA before the pitch. The investor wants to hear your idea, but you need protection if they decline and fund a competitor with your concept.
Scenario 2: Hiring a Contractor
You're hiring a developer to build a website. Use a Contractor Agreement covering scope, price, timeline, and IP ownership. If the developer will access customer data or business info, add an NDA to the agreement or as a separate document.
Scenario 3: Merger Discussions
You're exploring selling your business. Use a mutual NDA during due diligence so both parties can share sensitive financial and operational data. Later, use a separate acquisition agreement to define terms.
Scenario 4: Freelance Designer
You're hiring a freelance designer for a one-off project. Use a Contractor Agreement specifying design scope, revisions, payment ($X for Y deliverables), and that you own all designs. If the designer will see unreleased product mockups or brand strategy, add NDA provisions to the agreement.
Order of Signing and Timing
Always sign before disclosure. An NDA signed after information is revealed has much less legal weight.
For contractor engagements:
- Sign NDA first (before you share confidential info)
- Then sign Contractor Agreement when both parties are ready to begin work
Can You Combine Them Into One Document?
Yes. Many businesses create a single "Contractor Agreement + NDA" that covers both work terms and confidentiality. This is efficient and legally valid in Australia.
What Australian Law Says
Both NDAs and Contractor Agreements are governed by contract law in Australia. Courts will enforce them if they're:
- Clear and specific
- Not unreasonably restrictive
- Signed by both parties
- Made with mutual intent to be bound
Non-competes and non-solicitation clauses must be reasonable in scope and duration or courts will strike them down.
