Rule One – volunteer is under no obligation to do the work
Rule Two – the individual is watching, observing and learning rather than producing any work or research.
Under the Australian Fair Work Act 2009 (Cth), unpaid work is only lawful if:
the worker is a student undertaking a “vocational placement”, as defined in the Act; or
there is no employment relationship (for example, where an employee is a true unpaid intern or volunteer).
What that means is that a student can do work experience in your business for a defined period of time and be unpaid.
Volunteers can work for you in your business as long as there is no intention of forming an employment relationship and the volunteer is under no obligation to complete the work.
