Gilderoy flood map & planning overlays

The schematic on this page is a Gilderoy flood map: the mapped flood overlays drawn over the suburb's terrain and street grid, covering about 4% of the suburb. Flood lines vary block to block, so for a specific property use the free interactive map - search any Gilderoy address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

About 4% of Gilderoy falls within a mapped flood overlay, against the council-wide suburb average of 5%. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Gilderoy is mapped as bushfire-prone, compared with a Yarra Ranges average of 97%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Gilderoy is Public Conservation and Resource Zone (PCRZ), though the suburb also includes Rural Conservation Zone (RCZ3) and Green Wedge Zone (GWZ5). Zoning sets what you can build and do on a site, and can differ lot by lot.

Gilderoy 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 71 surveyed parcels in Gilderoy, the median lot size is about 9,805 m². There are also 37 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.

The wider Yarra Valley statistical area, which contains Gilderoy, went from 15,932 people in 2001 to 17,087 in 2025, up 7%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Gilderoy alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Gilderoy scores 976 and sits in decile 5 of 10 nationally and decile 4 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.
