What Is Accessorial Liability?
Under Section 550 of the Fair Work Act 2009, a person who is "involved in" a contravention of workplace law is treated as if they committed the contravention themselves. This means you don't have to be the employer to be held legally responsible for workplace breaches. If you played a role — even indirectly — you can face the same penalties.
If you helped, encouraged, advised, or caused someone else to breach workplace law, you are involved. This includes setting up pay arrangements you know are non-compliant.
If you pressured or incentivised a labour hire company to cut corners — whether through threats, promises, or unreasonably low contract rates — you may have induced the breach.
This is the broadest category. If you were in any way, by act or omission, directly or indirectly, knowingly concerned in the contravention, you are involved. This is the provision most commonly used against growers and directors.
If you and another party agreed or arranged for workplace law to be breached, both parties are liable — even if one party never directly employed anyone.
