How Minmi is zoned
Buying in Minmi? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 7.32 km², Minmi is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 96% is flagged bushfire-prone. There are 23 heritage-listed sites on record, and the dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 712 m² across 416 parcels. These figures are suburb-wide - the overlays that actually apply to a given lot can differ block to block, which is what a property-level check tells you.
