Suburbs with erosion hazard mapping

192 of the 1,264 Australian suburbs published on this site carry an erosion hazard mapping of some kind. That is a count of our own published pages, not of every suburb in the country — the corpus grows, and this page is rebuilt with it. They span 3 states, which between them use 4 different instrument names for it.

The practical effect is about siting and setback rather than construction standard. Where erosion is mapped, the question is how far back from the hazard a building must sit and what that leaves of the block — and on a narrow or shallow parcel that can be the difference between the house you planned and a different, smaller one. It is a question to resolve before a design rather than against a finished one.

2 of those 4 names say coastal explicitly; the rest do not. That is a difference worth noticing before assuming which hazard is being mapped: an instrument named for coastal erosion is scoped to a shoreline, while one named only for erosion is not telling you, from its name, what it covers. We report the names here, not the provisions behind them — the scheme or code your state publishes is where the scope is defined, and it is a short read.
