The numbers worked on paper. One overlay can change the yield by a third.

The contract is days away.

Zoning checks out. Title looks clean. Conveyancer's planning search returns nothing flagged.

Constraints. Liabilities. Yield.

The NSW Biodiversity Values Map. The current NVR category breakdown. The Plant Community Types and EEC status. The federal species records. The bushfire APZ implications.

All in NSW Government datasets. All sitting outside a standard contract review.

Screen the site. Before the contract.

WHAT A REPORT FLAGS BEFORE THE BAM

The cost of an overlay you didn't see compounds fast.

Biodiversity offset liability. A MapCheck ADVANCED report flags BSA viability and the Plant Community Types likely to drive credit demand. You know whether a formal BAM is going to land — before you're committed to commissioning one.

Yield implications. NVR category, bushfire APZ, flood overlay, riparian buffer, heritage curtilage — each can reduce buildable area. A report gives you the constraint footprint in hectares.

Timeline implications. Federal EPBC species records, native title status, council heritage listings — each can add referral or assessment time to a DA.

A MapCheck ADVANCED report covers all three at the screening stage — for AU$1,499 inc. GST per site, in 1–2 business days. Compare to a single BAM scoping conversation.

Decide which sites are worth the BAM. Before you commit to one.

WHAT WE'VE SEEN

A NSW developer screened a 5-site pipeline through MapCheck before LOI.

Two sites cleared without flags. Two carried significant offset liability — quantified to a credit-demand range. One was unviable at the listing price once the biodiversity layer was costed in.

Total spend: under AU$8,000 across 5 sites. Total time: 8 business days. The developer paid one LOI deposit instead of three.

"The numbers we needed to walk away from sites — before the LOI was on the table."

MULTI-SITE PIPELINES

For developers running more than one site at a time.

Each report is per-property, in the same plain-English format. Directly comparable across the pipeline.

Volume arrangements are available for pipelines of 5+ sites — talk to the team via the form above. NDAs are routine.

Standardised. Comparable. Defensible at IC.

Frequently asked questions

How does a MapCheck report fit into pre-acquisition due diligence?

As the first-pass environmental and planning screen. It tells you the constraint footprint, biodiversity offset exposure, federal species records, and the rest of the 140+ NSW Government layers — in plain English, before you're committed to commissioning a BAM or full ecological survey.

Does it cover Biodiversity Stewardship Agreement (BSA) and offset liability?

Yes. The ADVANCED tier (AU$1,499) includes a Conservation Profile section with a BSA Viability Score and indicative credit valuation. So you know whether a formal BAM is likely to land before you commit to one.

Does it replace a Biodiversity Assessment Method (BAM) report?

No. A MapCheck report is a preliminary screening tool — it tells you what's likely so you can decide whether to commission a formal BAM. It is not a substitute for a BAM, a BSSAR, or formal ecological survey.

Can we order multiple sites at once?

Yes. Each site is its own report. Volume pricing is available — mention pipeline size on the form above.

Can MapCheck deliver under NDA?

Yes. NDAs are routine for developer engagements.

Can we get structured data, not just PDF?

By arrangement for volume engagements. Talk to the team about structured outputs for internal feasibility models.

What the report covers

Zoning & planning

Land use zone (e.g. RU1, R1), Local Environmental Plan (LEP) provisions, State Environmental Planning Policy (SEPP) overlays including Housing and Biodiversity and Conservation. Minimum lot size, development standards where mapped.

Native vegetation

NSW Native Vegetation Regulatory (NVR) map categories — Cat 1 Exempt, Cat 2 Regulated, Cat 3 Vulnerable, Cat 4 Sensitive. Plant Community Types (PCTs) drawn from NSW BioNet, with Endangered Ecological Community (EEC) status where listed.

Biodiversity & credit potential

NSW Biodiversity Values Map, Biodiversity Corridors, threatened species records (Atlas of Living Australia: BioNet, SPRAT, iNaturalist, eBird, museums). On the ADVANCED tier: BSA Viability Score and indicative biodiversity credit value.

Bushfire & flood risk

Bushfire Prone Land categories (Cat 1, 2, 3), Asset Protection Zone (APZ) implications. Flood planning overlays where mapped at LGA level.

Water, soils & landform

Drinking water catchment, groundwater vulnerability, groundwater-dependent ecosystems, salinity risk, landslide risk, BSAL (Biophysical Strategic Agricultural Land).

Heritage, cultural & environmental

State Heritage Register, Environmental Planning Instrument (EPI) heritage layers, Aboriginal Places, Sensitive Aboriginal Land, Declared Wilderness, NPWS Estate, Wetlands (EPI), Littoral Rainforest, Coastal Environment and Use overlays.

Mining, subsidence & hazards

Mining Titles, Mine Subsidence districts, EPA Licensed Premises, asbestos (NOA), and a range of buffer overlays (odour, STP, explosive storage, landfill, airport, defence comms).

Native title, tenure & access

Native Title status, Crown land overlays, Travelling Stock Routes, road frontage and access classification, Koala Habitat (SEPP Biodiversity & Conservation 2021) and Koala Management Area (KMA).

Terms in plain English

NSW property terms — explained
BSA

Biodiversity Stewardship Agreement — a NSW Government-registered conservation agreement placed on title; manages land for biodiversity in exchange for tradeable biodiversity credits.

BSSAR

Biodiversity Stewardship Site Assessment Report — the formal site assessment a landholder commissions when progressing toward a BSA. Distinct from a MapCheck report; comes later.

PCT

Plant Community Type — NSW's BioNet classification of native vegetation communities. Some PCTs are listed as Endangered Ecological Communities (EECs).

EEC

Endangered Ecological Community — a plant community listed under NSW law as at risk of extinction.

NVR

Native Vegetation Regulatory map — NSW's spatial layer categorising land for clearing: Cat 1 Exempt through Cat 4 Sensitive.

BSAL

Biophysical Strategic Agricultural Land — land identified as having highly productive agricultural attributes; heightened protection under NSW planning law.

KMA

Koala Management Area — NSW maps the state into KMAs under SEPP (Biodiversity and Conservation) 2021. Triggers koala habitat assessment requirements for some developments.

LEP

Local Environmental Plan — principal planning instrument of a NSW LGA.

SEPP

State Environmental Planning Policy — NSW-wide planning instrument.

APZ

Asset Protection Zone — managed bushfire buffer around a building.

ALA

Atlas of Living Australia — Australia's pooled biodiversity data source (NSW BioNet + federal SPRAT + iNaturalist + eBird + museum records).
