The Fair Work (Registered Organisations) Act 2009 is a specialist federal law for registered organisations in the workplace relations system. From the structure of the Act, the main organisations in scope are employer associations, employee associations and enterprise associations that apply for, or hold, federal registration.
That means the Act is not a general compliance law for every Australian business, every chamber of commerce, or every industry group. It is directed to organisations that are registered under this federal scheme, and to the officers, employees, members and internal governance of those organisations.
For business owners, the most common practical connection is indirect. You may be affected because your business joins a registered employer association, receives representation from one, negotiates with a registered union, or is affected by a representation order, election issue, amalgamation or withdrawal involving a registered organisation.
