Dalmore flood map & planning overlays

The schematic on this page is a Dalmore flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 98% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Dalmore address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 98% of Dalmore falls within a mapped flood overlay, against the council-wide suburb average of 42%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Dalmore is mapped as bushfire-prone, compared with a Cardinia average of 98%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Dalmore is Special Use Zone (SUZ1), though the suburb also includes Green Wedge Zone (GWZ1) and Rural Conservation Zone (RCZ1). Zoning sets what you can build and do on a site, and can differ lot by lot.

Dalmore has 4 heritage-listed places on record. Heritage listing affects what you can alter or demolish, so confirm whether a specific property is listed or near a heritage place.

Across 163 surveyed parcels in Dalmore, the median lot size is about 83,424 m². There are also 28 registered easements mapped in the suburb - an easement can restrict where you can build, so always check the title and overlays for the specific lot.

At the 2021 Census Dalmore had 142 usual residents, with a median age of 50 and an average household size of 2.4 people. The wider Koo Wee Rup statistical area, which contains Dalmore, went from 5,236 people in 2001 to 12,598 in 2025, up 141%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Dalmore alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Dalmore scores 963 and sits in decile 4 of 10 nationally and decile 3 within Victoria - decile 1 being the most disadvantaged tenth of Australian suburbs and decile 10 the least. The national average score is 1000. SEIFA summarises income, education, occupation and housing across the whole suburb, so it describes the area, not any particular household in it.

Median household income in Dalmore was $1,792 a week at the 2021 Census, against $1,976 for the typical suburb in Cardinia. Median rent was $300 a week and the median mortgage repayment $1,970 a month. These are 2021 Census figures and have not been indexed to today.

A Dalmore planning report pulls every overlay - zoning, flood, bushfire, heritage, environmental and noise - that touches a single lot, on live council and state data. The interactive map preview is free; the full PDF report is $9.
