WattleAddr Property

Acid sulfate soils map by council, New South Wales

This is our simplified summary of the published map, not the map itself: to check one property, use the Planning Portal map or order the council's planning certificate. Each council shaded by the share of its addresses whose lot is at least partly on land a hazard map or planning overlay shows (at the address itself, for mine subsidence), counted among the addresses where that map applies: the same figures as each council page, from our weekly build of every address in the State. A map is a planning trigger, not a risk model. Select a council to see where the mapped land is.

Acid sulfate soils: share of addresses on land the map shows. Not a measure of risk. Build of 2026-09-12.

Partly mapped: the map covers only part of the council, so no share is given. Other classes: the map records its own classes, so no share is given. Not mapped: no map covers most of the council in the layers we read, which does not mean there is no hazard. Each council page explains its figure. Build of 2026-09-12.
