This is our simplified summary of the published map, not the map itself: to check one property, use VicPlan or order a planning certificate through LANDATA. 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.

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 applied: the planning scheme does not apply the overlay across most of the council, which says nothing about the land. Each council page explains its figure. Build of 2026-09-11.
