Free South Australia Odometer Disclosure Bill of Sale
An odometer disclosure statement certifies the recorded mileage on a vehicle at the time of sale. In South Australia, odometer tampering is an offence under the Motor Dealers Act and the Australian Consumer Law. A signed odometer disclosure creates a dated record that protects honest sellers and gives buyers documented recourse if the mileage was misrepresented. The disclosure should be completed as part of the bill of sale at the time the vehicle changes hands.

South Australia Odometer Disclosure Bill of Sale — What You Need to Know
Stamp Duty / Tax Details
Stamp duty on private vehicle sales in SA is $4 per $100 of market value. On a $25,000 car the duty is $1,000. Revenue SA assesses duty on the higher of the stated sale price or the market value (Redbook guide price).
Inspection / Roadworthy Requirements
SA does not require a roadworthy certificate for private car sales. No government inspection is mandated before the sale; the buyer may arrange a voluntary pre-purchase inspection at their own cost.
Registration
Registration for this vehicle type is handled by Service SA — separate from the transfer agency.
South Australia Odometer Disclosure Sale — Step-by-Step Checklist
- Record the exact odometer reading at the time of sale — photograph the instrument cluster as additional evidence.
- Seller certifies in writing that the odometer reading is accurate and has not been altered or replaced.
- If the odometer has been replaced, disclose the reason, the reading at replacement (if known), and the current reading.
- Both buyer and seller sign the odometer disclosure statement.
- Run a PPSR (Personal Property Securities Register) check and obtain a vehicle history report before signing.
- Retain signed copies of the disclosure for at least 6 years.
Common Pitfalls
- Approximate or rounded readings — always record the exact figure shown on the odometer.
- Failing to disclose a replaced odometer: this is a specific offence under Australian motor dealer legislation.
- Assuming the buyer won't verify: PPSR searches, RACQ/NRMA history checks, and service records all contain historical odometer readings.
- Odometer fraud carries criminal penalties in all Australian states, including fines and imprisonment.
Pro Tip
With SA's 1-business-day notification window, sellers should complete the online Notification of Change of Ownership at sa.gov.au before the keys even leave their hands. The higher $4/$100 stamp duty rate means both parties should have the exact sale figure agreed and documented before attending Service SA.
