Council outlines are simplified, and the mapped areas clipped, merged and simplified, by WattleAddr from the sources named; the publishers have not reviewed or endorsed this map.Each council is 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: drag to move the map, pinch, scroll with Ctrl or ⌘, or use + and − to zoom.

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 25 October 2026.
