The two registers, in plain English
PPSR is the Personal Property Securities Register, run by AFSA (the Australian Financial Security Authority). It's a record of secured loans against personal property — the legal database used by banks, finance companies, and the government to track who has a financial claim over what.
NEVDIS is the National Exchange of Vehicle and Driver Information System, run by Austroads on behalf of the state and territory transport agencies. It's the register of vehicle identity, registration history, write-off status, and stolen-vehicle flags — the data the police and insurance industry rely on.
| Question | PPSR answers | NEVDIS answers |
|---|---|---|
| Is there money owing? | ✅ | ❌ |
| Is it stolen? | ❌ | ✅ |
| Has it been written off? | ❌ | ✅ |
| Last-known kilometres? | ❌ | ✅ |
| Make / model / year | Partial | ✅ |
| Current rego status | ❌ | ✅ |
Why you need both for a real vehicle history check
A PPSR-only check tells you whether the car is encumbered — important for ownership transfer — but it tells you nothing about whether the car is mechanically a wreck rebuilt after an insurance write-off.
A NEVDIS-only check tells you the rego, kilometres, write-off and stolen status — but it tells you nothing about whether a finance company will turn up next week to repossess it.
Both checks are required for a complete picture. This is why Aussie Car Check's Essentials tier ($19.99) bundles both — running them separately on the government portals would cost you the same total but require two account signups and two payments.
Common scenarios both checks would catch
Scenario 1: You're looking at a 2020 Mazda CX-5 listed for $24,000. PPSR comes back clean. But NEVDIS shows the car was a repairable write-off in 2021 — its true market value is closer to $17,000 because the WOVR notation depresses resale forever. The seller didn't disclose this. With both checks you walk away or negotiate hard; with PPSR alone you overpay.
Scenario 2: A 2018 Toyota HiLux is advertised at $32,000 by a private seller in suburban Brisbane. NEVDIS shows the vehicle is in QLD with current rego and clean WOVR. Looks good. But PPSR shows a $24,500 finance encumbrance lodged by a non-bank lender. The seller is selling the car to clear personal debt without paying out the finance. If you buy it, you inherit the lender's right to repossess. NEVDIS-alone would have missed this entirely.
What about provider-specific reports?
Several private companies sell "vehicle history reports" — these are generally re-sales of the same PPSR + NEVDIS data, often with additional value-add (market valuation, recall history, common faults). Aussie Car Check is one of these — we're an approved B2B integrator with the Australian Government, so the underlying data is identical to what you'd get from the government portals directly. The value we add is making it cheaper and faster (one form, one payment, one human-readable report instead of two technical extracts).
Bottom line
PPSR alone misses half the picture. NEVDIS alone misses the other half. The $19.99 Essentials tier on Aussie Car Check covers both for the same total price as running them separately — that's the minimum due diligence for any private vehicle purchase over $5,000.
