Chain of Responsibility

All parties in the road transport supply chain have legal duties under the Chain of Responsibility (CoR) to help prevent breaches. This means everyone involved must actively work to avoid offences related to mass, load restraint, dimensions, fatigue, and speed. WesTrac can be held legally responsible if these obligations aren’t met. CoR laws also consider how the actions or inactions of off-road parties impact transport safety.

CoR Guides

Safety is a core SPARC value at WesTrac, and to reduce Chain of Responsibility (CoR) risks, a cross-business working group has developed simplified load restraint guides and mass/dimension data. The group is also focusing on CoR training to ensure staff understand the laws, risks, and how to stay safe.

Eftsure Supplier Verification

WesTrac uses Eftsure, an independent verification platform, to confirm supplier information and help protect both our business and our suppliers from fraud or payment error. All suppliers must complete the Eftsure verification process before conducting business with us or receiving payment. 

Eftsure independently validates key supplier information to ensure payment details are accurate and legitimate. This includes a confirmation call to new suppliers to verify their details as part of the onboarding process. 

During the Eftsure verification process, suppliers will be asked to provide:  

  • Bank details 
  • ABN 
  • Trading name 
  • GST registration 
  • Company contact information.  
For existing suppliers

If your business details change, please contact the Vendor Management team at any time. They will issue an ‘Eftsure Change Request’ allowing you to securely update your information. 

It is the responsibility of each supplier to ensure their details remain current. Please notify us immediately if you identify any changes or discrepancies.

For new suppliers

As part of your onboarding, the Vendor Management team will request your company name and email address. You will then receive an email invitation from Eftsure to register your details, including: 

  • ABN 
  • Company name 
  • Business address 
  • Contact email 
  • Bank account details 

An Eftsure team member may contact you within 24 – 48 hours to verify your information. You will receive a confirmation email once your details have been successfully verified.
