What a $9 report adds for a Southwest address
This page is the suburb; the report is your lot. For any Southwest address it resolves, on the lot boundary:
- The zone and every planning overlay that touches the lot, in the scheme's own labels
- Which flood overlay categories reach the lot
- Whether the lot is in bushfire-prone mapping, and what that triggers for a build
- Whether the lot, or a neighbour, is one of the 6 heritage-listed places on record
- A coverage disclosure: exactly which layers were, and were not, assessed
