How Olney is zoned
Buying in Olney? 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 127.54 km², Olney 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, 100% is flagged bushfire-prone. The dominant land-use zone is Forestry. The median lot measures about 1,285,797 m² across 8 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.

Cessnock is the authority to check for flood mapping in this area. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Yes - around 100% of Olney is mapped as bushfire-prone, compared with a Cessnock average of 91%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.
