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 the odometer
  • removing or replacing the odometer
  • rendering the odometer inoperative or inaccurate by any means whatsoever
  • fitting 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:

  • haven't reported the matter prior
  • the suspect odometer reading isn't being reviewed by a court or tribunal.

What you need

  • your personal 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. Complete the online report form.
  3. Select 'Submit'.

More information

  • Odometer interference can result in very severe penalties, and an offending motor dealer or repairer may also be liable to pay the losses of a purchaser through civil action.
