How to lodge a complaint about Motor Vehicles

If you have not been able to get any satisfaction by approaching the trader, you can make a formal complaint to Consumer Protection. We will advise you, and where appropriate, attempt to negotiate a resolution to the dispute.

How to lodge a complaint

We prefer that you lodge a complaint in writing. However, if you have a disability which makes it difficult for you to complete forms, you can contact our telephone advisory service on 1300 30 40 54 and ask if you can lodge the complaint by phone.

You can lodge a complaint by:

  • downloading and completing a Consumer Protection Complaint Form, and mailing it to:
    Department of Commerce
    Locked Bag 14
    Cloisters Square
    PERTH WESTERN AUSTRALIA 6850
  • phoning the Department of Commerce between 8.30am and 5.00pm Monday to Friday, on 1300 30 40 54 and requesting a Complaint Form be sent to you.
  • visiting between 8.30am and 5.00pm Monday to Friday to pick up a Complaint Form in person.
    Department of Commerce
    Ground floor Reception
    219 St George's Terrace

    or

    Motor Vehicles Branch
