What we check
Every check, named, and where it runs.
Every report states exactly how many checks ran at that address, and which ones didn't. The exact checks run depend on the address, state and available coverage. Each one is cited in your report, for a standing home or an empty block alike. Here's the full list, with an honest map of which run Australia-wide versus which depend on your state.
Sourced from government publishers — Geoscience Australia, the Bureau of Meteorology, state EPAs and planning departments, heritage registers and land & spatial-services agencies.
How we test ourselves
The platform is tested as carefully as the property.
These test KRAYN's own software and the reports it has produced.
212
automated tests run on our deploy path. Any one of them can stop it.
What they will not let a report say:
REFUSED
"Largely clear — a few things to check"
on a report whose own checks found a major issue.
KRAYN
The verdict is raised to meet the worst finding.
What stands behind it
The verdict is simple. The work behind it isn't.

These answer two different questions. The first is what a single address has actually produced; the rest are what KRAYN holds. They are not steps in one total and should never be added together.

Beyond the checks
Not just the data. What it works out for you.
The checks above are the facts. From them, the report reads the site — what shapes development, and what typically adds to cost and why. Each is shown on a real sample.
What the report works out
What shapes development herezone, statutory purpose, lot & overlays (VIC and NSW)
What typically adds to build cost, and whyfactors to budget for — never a dollar figure
Coverage varies by state
Some checks run everywhere. Others depend on your state.
We won't pretend coverage is uniform. National datasets run for any Australian address; the statutory-planning layers are deepest in Victoria, and depth varies by jurisdiction. Every report names which ran for your address.
Runs for every address · in every state
These national datasets run for any Australian address, whatever a state's shading below. The map shades only the state-dependent layer — a lighter state is never an empty one. Thinner never means nothing.

Every report names which checks ran for your address — and which didn't.
Registered easements & utility mains — identified
KRAYN shows the indicative location of registered easements and sewer / water mains crossing a parcel, identifies the authority or provider that owns them, and flags the build-over consent they imply — read directly from the authorities.
Exact location & depth — confirm before you dig
For the precise location, depth and dig-safety detail of any service, contact Before You Dig Australia (BYDA) or the relevant provider directly before you dig or build. KRAYN identifies what's there and who owns it; BYDA and the providers hold the detailed locate information.
Former swamp, landfill & acid sulfate soil
What runs depends on where you are — three lanes, and one honest set of limits.
VIC
Your parcel is checked against the EPA Victorian Landfill Register (state statutory register), the state Coastal Acid Sulfate Soils mapping, and the Victorian Wetland Inventory — current and 1788 (pre-European) extent. These lanes run for Victorian addresses today.
NSW
The coastal acid sulfate soil lane runs against the NSW acid sulfate soil planning maps and the NSW ASS risk mapping, for coastal and tidal-river-valley parcels.Inland NSW is checked. The mapping is regional in scale, so an unmapped parcel returns checked · caveat — never clear. Absence of a mapped area is not evidence that no constraint exists.
Every address
Across every Australian state and territory, a national waste-facility context lane — the Geoscience Australia National Waste Management Facilities Database (CC BY 4.0) — checks your parcel's surroundings for nearby landfill and waste facilities as proximity context. It is never authoritative.
The honest limits
These registers are incomplete — the landfill register doesn't capture every historical or unregistered tip — and the wetland and acid-sulfate layers are area-scale. A “no match” is never a clearance, on any of these lanes. The 1788 (pre-European) wetland extent is a deduced historical reconstruction, not a present-day ground test; where it flags, it's a prompt for a geotechnical investigation, not a determination.
See them on real reports: a Patterson Lakes home on mapped prospective acid sulfate soil and former swampland, a Springvale property about 33 m from a registered closed landfill, and a Booragul home in New South Wales on mapped Class 1 coastal acid sulfate soil.
What the public record says about value and consent
Two lanes read the record around your parcel rather than the ground under it — and both are stated with the jurisdiction they actually cover.
NSW
Official land values — the NSW Valuer General's determined value for the land, every year from 2012, shown as the record states it.14 annual base dates to July 2025 (held as at 2026-09-03), joined to your parcel on lot and plan. It is the determination as published — not an estimate, and not a market appraisal of the property.
NSW · VIC
The street's consent record — what a report lists near your boundary, stated only for the jurisdictions where the section appears — not implied to be national. New South Wales: applications and complying development certificates within 200 m, counted again at 500 m and 1 km, with certifier outcomes where determined, and the largest nearby subdivision flagged. Certificates are counted because much low-rise work never appears as a development application at all. Victoria: located planning applications within 200 m, each with its determination as the register records it. Applications without a mapped location are not shown, so the list is not a complete count.
How we keep it honest
Every report names exactly which checks ran for your address, and which didn't. The absence of a flagged finding is not a clean bill of health. Coverage varies by state (Victoria is deepest); we tell you what applied to your specific site, and what to verify with the relevant authority.
