It's an offence in NSW to interfere with an odometer reading, and the Motor Dealers and Repairers Act 2013 deems interference to be:

  • altering the reading of an odometer
  • removing or replacing an odometer
  • rendering an odometer inoperative or inaccurate by any means whatsoever
  • fitting or possessing a device capable of rendering the odometer inoperative or inaccurate.

If you suspect an odometer has been tampered with, you can report the matter to the NSW Office of Fair Trading. If they find that the law has been broken, they'll inform the trader and take the action required to protect other consumers.


You're eligible to make a report if:

  • you have not already reported the matter
  • the suspect odometer reading is not being reviewed by a court or tribunal.

What you need

  • your personal and contact details
  • a summary of the issue
  • details of the vehicle
  • details of the business/seller of the vehicle
  • any supporting documents, such as receipts, invoices, and/or contracts for the vehicle.

How to report

  1. Select the 'Report online' button.
  2. Follow the prompts to complete the online report form.
