Is A Non-Compete Clause Enforceable in Australia?
A non-compete is enforceable in Australia only if it protects a legitimate business interest and is no wider than reasonably necessary in duration, geography, and scope — the same common-law reasonableness test applied in the UK and Singapore. Australian courts start from the presumption that a restraint of trade is void and place the burden on the employer to justify it.
This page describes the general approach Australia law takes to this clause type — it is informational, not legal advice on any specific contract. Enforceability in a real dispute depends on the exact wording, the specific facts, and current law, all of which can change. Have your actual clause reviewed by a lawyer before relying on it.
How Australia approaches this
Australia operates a single federal common-law system for this purpose, so the reasonableness test applies fairly consistently nationwide rather than varying meaningfully state by state — unlike the state-by-state divergence seen in the US. Some state legislation gives courts additional flexibility to read down an unreasonably broad restraint to what would have been reasonable, rather than requiring the clause to fail outright or be blue-pencilled in the English style.
As with the UK and Singapore, courts weigh duration, geographic area, and the scope of restricted activity together, and assess them against the employee's actual seniority and the specific interest genuinely at risk — trade secrets, client connections, or the stability of a specialised workforce, not competition in the abstract.
A restraint drafted as a blanket, company-wide clause applied uniformly regardless of role is considerably more likely to fail than one scaled deliberately to the individual's actual access and seniority.
What determines the outcome
- Whether a genuine legitimate business interest is being protected, not just competition generally
- Whether duration, geography, and scope are each individually reasonable for the specific role
- The employee's actual seniority and access to clients or confidential information
- Whether the relevant state's legislation permits a court to read down an excessive restraint rather than void it entirely
Practical guidance
- Scale the restriction to the individual's actual seniority and access rather than using a single company-wide template
- Tie the restraint explicitly to a specific, identifiable interest rather than competition generally
- Draft with realistic, defensible limits from the outset rather than relying on a court to read the clause down after the fact
