Which contamination registers does the score check?

Victoria, NSW and Western Australia publish official contaminated-land registers we query live. Queensland, South Australia, Tasmania, the ACT and the NT keep records too, most of them behind a per-lot or manual search, and we have not integrated those yet. Scores there use current industrial proximity and the response flags the register as not integrated so you can check the state's own records directly.

What counts as an industrial proximity signal?

How close the address is to land uses operating there today with the strongest contamination track record: fuel stations, factories and industrial facilities, dry cleaners and similar. It is a snapshot of what is around the address now, not a record of what used to be there, so it is a proxy for soil and groundwater risk and is labelled as one.

Does a clean score mean the land is uncontaminated?

No. It means no register site or major industrial signal was found nearby. Registers only list known, notified contamination. For transactions where it matters, a professional site history and environmental assessment is the appropriate tool.

Contamination Risk Score — EPA Registers + Industrial Proximity for Any Australian Address

The Problem

Known contamination records are public. Finding them isn't easy.

Old fuel depots, dry cleaners and factories leave legacies in soil and groundwater that outlast the buildings.

Registers are state silos

Each state EPA publishes its register differently, some as searchable maps, some barely at all. Nobody checks three systems for one address.

The register is the floor

Registers list confirmed, notified sites. Plenty of historical industrial land never made the list.

Due diligence comes late

Site contamination usually surfaces at the environmental assessment, deep into a purchase. Early screening is almost free by comparison.

Live Example

What the register knows about a street.

The street map settles into a soil view while official register records are checked to 2 km and current industrial land uses to 500 m. Every mapped record stays where it is: red for official register records, amber for industrial land uses and grey for former-use records. Click a record to inspect it.

Honest by Design

A proxy is never dressed up as a register.

3/8

states with official registers we can query

Queensland, SA, Tasmania, the ACT and NT keep contaminated-land records of their own, but we have not integrated any of them yet. Scores there rely on industrial-proximity signals alone, and the response marks the official register as not integrated for that state so you know to check it yourself.

What we measure, and what we don't

The difference between “the EPA has a record near this address” and “there is a fuel station nearby” matters enormously. Our responses never blur the two.

Where a register exists and returns nothing, that is also stated: checked, no hit. Absence of evidence is only meaningful when you know something was actually checked.

How It Works

Official registers first, current industrial neighbours everywhere.

Two signal layers, and the response is explicit about which one applies.

Official EPA registers

We query the contaminated-land registers of Victoria, NSW and Western Australia live. A register site near the address is the strongest signal there is, and it dominates the score.

Industrial proximity

Nationwide, we measure how close the address sits to the land uses operating there now that generate most contamination legacies: fuel stations, factories, dry cleaners and similar industrial points. This is a present-day map of the neighbourhood, not a record of what used to be there.

Distance-weighted scoring

Signals decay with distance. A register site at 100 metres and one at 900 metres are very different findings, and the score reflects that.

Distance decay 0-100 score

The Register Sweep

Checked is not the same as clean.

A register record is official evidence; a nearby fuel station is only a labelled proxy — the same 500 m sweep reports each for exactly what it is.

Checked, no hit score 95 · very clean

queried live in VIC, NSW and WA — and every response says whether the register was hit, checked with no hit, or not available.
