A history check turns a car's past from a mystery into a document. In Australia the starting point is the PPSR, and it takes about a minute.
What the PPSR is
The Personal Property Securities Register is a national government database run by the Australian Financial Security Authority. It replaced the old state-based registers such as REVS, so the same search works no matter which state the car is in. You search using the VIN — the 17-character number found at the base of the windscreen, in the driver's door opening or under the bonnet.
Security interest — money owing
This is the headline item. If a finance company has registered an interest against the car, the debt follows the car, not the seller. If the seller stops paying after you buy it, the lender can repossess the vehicle from you and you lose both the car and your money. A clear result here is the main reason to run the check.
Written-off status
There are two kinds and the difference matters. A repairable write-off was uneconomical for an insurer to fix relative to its value — hail damage is a common cause. It can be repaired and re-registered, but it is worth less and some insurers will limit cover. A statutory write-off has damage so severe it cannot legally return to the road. Never buy one to drive.
Stolen status
The report flags vehicles recorded as stolen. If you unknowingly buy a stolen car, it can be taken back and you are unlikely to recover what you paid.
Know the limits
Written-off, stolen and vehicle description data comes from state road agencies and police through a system called NEVDIS, and it is not always complete or instantly up to date. A clear PPSR is excellent news, but it is not a substitute for a mechanical inspection — it says nothing about the condition of the engine.
How to use it properly
Run the search immediately before you pay, not a week earlier, because a new interest can be registered at any time. Check that the VIN on the report matches the VIN physically stamped on the car and the registration papers. Then save the search certificate — it is your legal record of the result.
Paid history reports from commercial providers layer on extras such as odometer readings, recall notices and sometimes accident data. Useful, but start with the official search.
