WHS duties in a contractual chain: Factsheet

This fact sheet provides information for persons conducting a business or undertaking (PCBUs) who are working as part of a contractual chain. 

A contractual chain refers to the situation where, in relation to the same project or work matter, there are multiple contractors and subcontractors. 

A contractual chain can form in any industry but is a common way of conducting business across the economy, for example in industries such as building and construction, road transport and events management. 

It provides guidance on duties under the model WHS laws and examples of how contractual relationships fit within the model WHS framework. This includes individual contractors and self-employed persons, who may be both a PCBU and a worker in a contractual chain.
