How Diamond Head is zoned
Buying in Diamond Head? 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 28.86 km², Diamond Head is highly constrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. Of what is mapped, 64% is flagged bushfire-prone. The dominant land-use zone is National Parks and Nature Reserves. The median lot measures about 170,639 m² across 27 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.
