Wildwood flood map & planning overlays

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

Flood mapping covers Wildwood and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 4%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Wildwood is mapped as bushfire-prone, compared with a Hume average of 45%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

About 38% of Wildwood sits inside a published aircraft noise contour. ANEF contours are forecasts published per airport and used to control noise-sensitive development; they are not a measurement at any one house, and a property can sit under a flight path and outside every contour.

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

Wildwood has 9 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 125 surveyed parcels in Wildwood, the median lot size is about 167,407 m². There are also 142 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 Wildwood had 244 usual residents, with a median age of 44 and an average household size of 2.9 people. The wider Sunbury statistical area, which contains Wildwood, went from 10,282 people in 2001 to 15,364 in 2025, up 49%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Wildwood alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Wildwood scores 1041 and sits in decile 8 of 10 nationally and decile 8 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 Wildwood was $1,765 a week at the 2021 Census, against $1,683 for the typical suburb in Hume. Median rent was $550 a week and the median mortgage repayment $1,632 a month. These are 2021 Census figures and have not been indexed to today.

A Wildwood 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.
