PropertyFlags · guideContaminated land checks in NSW, in plain language
Contamination is the quietest risk in property: invisible at the inspection, rarely mentioned by anyone selling, and documented in registers most buyers have never heard of. Here is what the official record actually covers, how to search it free, and what a former petrol station near the address really means.
What the official record is
NSW keeps a public record of contaminated sites notified under the Contaminated Land Management Act. Each entry names the land, the contamination activity and a regulation status: whether the EPA currently considers it significant enough to warrant regulation. Former service stations, dry cleaners, gasworks and industrial land dominate the list, which tells you something about where the risk concentrates.
The record is honest about its own limits, and you should be too when reading it: it holds sites somebody notified. Land with an unreported history, uses that predate the notification system, and contamination managed through planning conditions instead of the Act are simply not in it.
How to check, free
Search the EPA public record of notified sites by suburb and read every entry near the address, not just on it: plumes and groundwater do not respect lot boundaries. Then read the contamination notations on the section 10.7 certificate in the contract of sale. If the land itself has an industrial or agricultural past, the next step up is a commercial site history search, and for real concern, an environmental consultant.
One more register worth knowing: environment protection licences. These are not contamination records; they are permissions for current industrial operations, waste handling, crushing and similar. A licensed operation near a home is a regulated neighbour, not a contaminated one, and it is still something you want to know before you commit.
The 60 second version
A PropertyFlags report checks every NSW address against both registers in one pass: notified contaminated sites within 500 m, and licensed industrial operations within range, each with its name, distance and regulation status, alongside flood, bushfire, zoning, defect orders, development activity and noise. A nearby notified site under active regulation is flagged for review with the entry named; an empty result is reported as exactly that, with the register's limits stated on the same page.

Common questions
How do I check if land is contaminated in NSW for free?
Start with the NSW EPA public record of notified contaminated sites: it lists land notified under the Contaminated Land Management Act, searchable by suburb, with each site's regulation status. Then read the contamination notations on the section 10.7 certificate in the contract. Neither is a full history; they are the official starting points.
Is buying near a former petrol station a problem?
Sometimes, and the honest answer is that distance and groundwater direction matter more than the fact itself. Underground fuel tanks can leak into soil and groundwater and plumes can travel; that is why service station sites appear so often on the register. A nearby entry is a question to put to the EPA record and your conveyancer, not a verdict on your lot.
The register shows nothing at my address. Is the land clean?
Not proven, no. The register lists only sites that were notified to the EPA and assessed as warranting attention. Contamination nobody has reported, historical uses that predate the system, and sites managed under planning conditions rather than the Act do not appear. An empty result is evidence, never a guarantee; for land with an industrial past, a site history search is the next step.
What does the regulation status on an entry mean?
Roughly: whether the EPA considers the contamination significant enough to warrant regulation right now. A site can be listed but marked as not requiring regulation, often because it was remediated or the risk is managed. Both states are worth knowing about; they mean different things for what you ask next.
Does PropertyFlags check contamination automatically?
Yes, two ways for every NSW address: notified sites within 500 m from the EPA contaminated land record, and licensed industrial operations within range under the environment protection licensing scheme. Each finding names the site, the distance and the register it came from, and the report never presents an empty result as a clean bill of health.
