Free South Australia Vehicle Bill of Sale
South Australia applies one rulebook to every light motor vehicle — sedan, ute, van, SUV, light truck under 4.5 tonnes GVM — and that rulebook has two defining features: the nation's steepest duty at $4 per $100, assessed on the HIGHER of price and market value, and no inspection requirement of any kind. For SA's ute-heavy private market that combination puts everything on the paperwork: the bill of sale documents the true price (and the condition that justifies it, because Revenue SA checks against book), the PPSR search covers the finance risk on work vehicles, and Service SA processes the transfer while the seller's disposal notice closes out liability.

South Australia Vehicle Bill of Sale — What You Need to Know
Stamp Duty / Tax Details
Duty is a flat $4 per every $100 of market value across body types — the steepest flat rate in the country, $1,000 on a $25,000 vehicle. Revenue SA uses the higher of price or Redbook value.
Inspection / Roadworthy Requirements
No roadworthy certificate is required to sell any light vehicle privately in SA; a pre-purchase inspection happens only if the buyer organises and pays for one.
Registration
Registration for this vehicle type is handled by Service SA — separate from the transfer agency.
South Australia Vehicle Sale — Step-by-Step Checklist
- Identify the vehicle fully: VIN, plate, body type, odometer — one set of rules covers everything under 4.5 t GVM.
- Record the true price with condition notes — duty is $4 per $100 on the higher of price and market value.
- Buyer: run the ~$2 PPSR search — work utes and ex-ABN vehicles carry finance routinely.
- Buyer: arrange your own inspection — SA mandates none, on any vehicle class.
- Buyer transfers at Service SA and pays duty; seller lodges the disposal notice promptly.
Common Pitfalls
- Nominating a soft price on a work vehicle — Revenue SA assesses the higher of price and market value regardless.
- Skipping the PPSR on an ex-business ute — SA's commercial fleet turnover makes encumbrances common.
- Assuming some inspection regime exists — no SA authority checks the vehicle at any point in a private sale.
- Leaving the disposal notice unfiled and wearing the buyer's expiation notices.
Pro Tip
SA vehicles: one rulebook under 4.5 tonnes — document the price like Revenue SA is reading (it is), inspect like nobody else will (they won't).
