How Harrison is zoned
Buying in Harrison? The Territory Plan zone on this page sits alongside the Crown lease, which sets what a block may actually be used for - a $9 planning report pulls the zone and every overlay at the block level for any Harrison address.
Across its 2.92 km², Harrison is moderately constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay, and 25% is flagged bushfire-prone. There are 19 heritage-listed sites on record, and the dominant land-use zone is Urban Residential. The median lot measures about 481 m² across 1,797 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.
