Industrial action is governed by the Fair Work Act. Here is an excerpt from
the Fair Work Australia website
Unlawful industrial action
Industrial action is unlawful if it’s engaged in when there’s an enterprise agreement in place that covers the employee, employer or employee organisation that hasn’t passed its nominal expiry date.
The Fair work Commission must suspend or stop any unlawful action. Court orders can also be used to enforce this.
Consequences of unlawful action
If you take part in unlawful industrial action, some individuals or organisations can take court action against you. These individuals or organisations include:
anyone covered by the enterprise agreement who is affected by the action
anyone else who is affected by the action (e.g. a business that lost money because it couldn’t get hold of goods it needed)
the Fair Work Ombudsman (us).
The court can order you to pay either or both:
compensation for losses
fines.
The ability to strike in Australia has been all but eliminated with virtually unlimited liability on any person or organisation that takes part.
