Medicinal cannabis and workplace testing in South Australia
Model WHS law — testing regimes vary widely between employers Last verified:
Unfair dismissal is federal law — the Fair Work Act and the case database apply the same in every state. What changes in South Australia is the layer around it: the safety statute, the discrimination statute, the roadside rules, and where to get help.
How the layers stack in SA
- Dismissal and general protections: federal — Fair Work Act 2009, the 21-day deadline, and everything in the case database applies here unchanged.
- Work health and safety: Work Health and Safety Act 2012 (SA), administered by SafeWork SA. This is the statute that grounds your employer’s duty to manage impairment risk — and their obligation to consult the workforce on the policy.
- Discrimination: Equal Opportunity Act 1984 (SA), alongside federal disability discrimination law. State and federal routes have different processes and deadlines — one reason early advice matters.
- Roadside: No general prescription defence for detectable THC while driving as at our last review. Roadside law is its own minefield — our companion driving-law hub covers SA in detail.
What’s distinctive about SA
South Australia's mix of defence industry, wine and agriculture, and long-haul transport means testing regimes vary enormously between workplaces - which makes reading your specific policy, rather than relying on industry folklore, the whole game.

For individual advice: the Legal Services Commission of South Australia, community legal centres, and the Fair Work Commission. Free first consultations are common at employment firms — the Dismissal Response Kit’s lawyer briefing pack is designed to make those first calls count.
