Plain-English reference

Car auction & write-off glossary

Every term you'll meet buying a car at an Australian auction, explained in plain English — from repairable write-off and WOVR to reserve, passed in and buyer's premium. Regulatory terms vary by state — the linked guides carry the detail.

Write-off & title status

Write-off
A vehicle an insurer (or owner) has declared a total loss — not economical to repair relative to its value. In Australia it is then recorded on the Written-Off Vehicles Register (WOVR). WOVR explained →
Repairable write-off (RWO)
A written-off vehicle whose damage was assessed as repairable. Depending on the state, it can be repaired and returned to the road after passing the required inspections. Repairable write-off guide →
Statutory write-off
A vehicle with damage so severe that, under current Australian rules, it cannot be re-registered for road use anywhere in the country — it is for parts, dismantling or export only. The categories are set by each state. Statutory write-off guide →
WOVR (Written-Off Vehicles Register)
The register that records a vehicle's write-off status and category. Once recorded, the status stays with the vehicle permanently and shows on a PPSR check. Exactly what's captured varies by state — most registers cover light vehicles, with heavy vehicles often recorded separately. WOVR explained →
Inspected / passed write-off
A repairable write-off that has already passed a written-off vehicle inspection in some states. Terminology varies by state.
Damage category
The classification the assessor or auction assigns to describe the main damage — for example impact (collision), hail, water/flood or vandalism. It strongly affects price. Prices by damage type →

The auction process

Salvage auction
An auction selling damaged, written-off or end-of-life vehicles, typically sourced from insurers and fleets.
Lot
A single item in an auction — here, one vehicle — identified by a lot number.
Simulcast / live online auction
A real-time auction with a live auctioneer that you watch and bid in online as it happens (for example Pickles Simulcast).
Timed online auction
An online auction that runs for a set period and closes at a deadline, with no live auctioneer — closer to eBay-style bidding.
Tender / Expression of Interest (EOI)
A sale where you submit a sealed offer by a deadline instead of bidding openly. The highest or best offer is accepted.
Buy Now
A fixed price to buy a lot immediately, without bidding.
Reserve price
The minimum the seller will accept. If bidding doesn't reach it, the lot is "passed in" rather than sold.
Passed in
A lot that did not sell because bidding failed to meet the reserve. It may be negotiated afterwards or relisted.
Hammer price (knockdown price)
The winning bid amount — what the vehicle "sold" for — before buyer's premium, fees and GST. See real hammer prices →
Proxy / auto bid
You set the maximum you're willing to pay and the system bids on your behalf up to that limit.
Relisted
A lot offered again at a later sale, often after it passed in.

Costs & fees

Buyer's premium
A fee the auction adds on top of the hammer price, usually a percentage and often capped. GST generally applies. It is the main cost on top of your bid. Buyer fees, broken down →
Documentation / admin fee
A fixed fee per vehicle covering paperwork and transfer.
GST
The 10% Goods and Services Tax. It may apply to the hammer price and/or the fees, depending on the seller and the vehicle.
Deposit
An amount taken at the fall of the hammer to secure the purchase. The balance is due shortly after, usually by bank transfer. The full payment flow →
Storage fee
A daily charge that applies if you don't collect the vehicle within the free storage window.
Transport / towing
Moving the vehicle from the auction yard. Write-offs often can't be driven away, so most buyers arrange a tow or transporter.

Buying & ownership

ABN (Australian Business Number)
A business identifier. You do NOT need an ABN to buy at the major salvage auctions as a private individual — you need one (and the right licences) only to trade vehicles or parts commercially.
Dealer licence
A motor-dealer licence required to sell vehicles commercially. It is not required to buy a car for yourself.
Private buyer
An individual buying for themselves. At most major salvage houses, anyone 18 or over with an ID-verified account can buy — though some sales or lot types are restricted to licensed dealers or wreckers.
Zero-balance / clearance invoice
The paid-in-full invoice issued once your funds clear. You need it (plus photo ID) to collect the vehicle.
Authority to collect
A signed authorisation letting a third party — such as a transporter — collect a vehicle on your behalf.

Checks & due diligence

PPSR (Personal Property Securities Register)
A national check on a vehicle by VIN. It reveals money owing (encumbrance), theft records and write-off (WOVR) status. Always run one before you commit. How a PPSR check works →
VIN (Vehicle Identification Number)
The unique 17-character identifier on the vehicle, used for PPSR/WOVR checks and identity inspections.
Encumbrance (finance owing)
Money still owed on the vehicle under finance. If unpaid, it can follow the car to a new owner — which is why a PPSR check matters.
Compliance plate / build date
Markers of when the vehicle was built and complied for Australian roads. Used in identity inspections.
Registration status
Whether the vehicle is currently registered, unregistered or cancelled.
Odometer
The recorded distance the vehicle has travelled, in kilometres.

Repair & getting back on the road

Roadworthy certificate (RWC)
A safety-inspection certificate required to register a vehicle. The name varies by state — roadworthy certificate, pink slip / eSafety, safety certificate, and so on. Inspect & re-register →
Identity inspection (VIV / VIIU / WOVI)
A written-off-vehicle identity check (anti-rebirthing) you must pass before re-registering a repaired write-off. The name and responsible body vary by state — for example VIV in Victoria, VIIU in NSW, WOVI in Queensland — and some states also require a separate general unregistered-vehicle inspection (in NSW, the "blue slip" / AUVIS).
VASS (Vehicle Assessment Signatory Scheme)
A Victorian engineering sign-off required for modifications — not for standard repair back to original specification.
SRS / airbag report
A report confirming the supplementary restraint (airbag) system was correctly repaired, generally required where airbags were deployed.
Re-registration
Returning a repaired repairable write-off to the road after it passes the identity and roadworthy inspections. Allowed in most states once it passes — but New South Wales generally blocks open-market buyers from re-registering a light repairable write-off (narrow exceptions apply, such as the prior owner, an heir, or hail-only damage). Rules and scope vary by state, so check before you bid. The re-registration process →

Vehicle condition

Runs & drives
The auction's note that the vehicle started and moved under its own power at inspection. It is an observation, not a guarantee.
Keys present
Whether keys are included with the lot.
Salvage / wreck
A damaged vehicle sold for repair or for parts. Buying for parts →
Hail damage
Dents from hail. Often cosmetic and the car is usually mechanically sound — but heavy hail can crack glass and let water in, so still inspect it. Hail write-offs tend to sell for more than crash-damaged ones. Damage vs price →
Water / flood damage
Damage from immersion. It can cause hidden electrical, corrosion and drivetrain faults that resurface for years — among the riskiest repairs to take on.
