Heidelberg flood map & planning overlays

The schematic on this page is a Heidelberg flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 22% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Heidelberg address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 22% of Heidelberg falls within a mapped flood overlay, against the council-wide suburb average of 12%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 27% of Heidelberg is mapped as bushfire-prone, compared with a Banyule average of 13%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Heidelberg is Housing Choice and Transport Zone (HCTZ2), though the suburb also includes Activity Centre Zone (ACZ2) and General Residential Zone (GRZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.

Heidelberg has 35 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 4,682 surveyed parcels in Heidelberg, the median lot size is about 655 m². There are also 1,053 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 Heidelberg had 7,360 usual residents, with a median age of 39 and an average household size of 2.3 people. The wider Heidelberg - Rosanna statistical area, which contains Heidelberg, went from 12,805 people in 2001 to 16,925 in 2025, up 32%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Heidelberg alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Heidelberg scores 1085 and sits in decile 10 of 10 nationally and decile 10 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 Heidelberg was $2,012 a week at the 2021 Census, against $2,072 for the typical suburb in Banyule. Median rent was $400 a week and the median mortgage repayment $2,150 a month. These are 2021 Census figures and have not been indexed to today.

A Heidelberg 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.
