What we check
Every check, named, and where it runs.
More than twenty checks across six areas — read against 60+ government datasets, each 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.

Land & soil resource
Broad-scale, regional mapping — context, not a parcel-level soil test, and it never moves the verdict.
Land & soil capabilityregional class — NSW LSC, VIC land systems (WA, SA where covered)
Salinityregional salinity rating + risk
Groundwater / aquiferthe regional aquifer system (BoM) — never site groundwater
Groundwater — boresnearby registered bores (BoM NGIS) — regional context, or not available here; a bore is never a site finding
Surface geologythe mapped surface-geology unit (VIC / NSW seamless geology) — regional context, not a site sample
Soil hazardswater + wind erosion, acidity, water-storage, ease of excavation

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 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 thinner elsewhere. 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.

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 returns an honest no-coverage — never a clearance.
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 on a registered closed landfill, and a Booragul home in New South Wales on mapped Class 1 coastal acid sulfate soil.
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.
