Narracan flood map & planning overlays

The schematic on this page is a Narracan 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 Narracan address and it shows the flood, zoning and bushfire mapping on the exact lot boundary.

Flood mapping covers Narracan and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 6%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

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

The dominant planning zone in Narracan is Farming Zone (FZ), though the suburb also includes Farming Zone (FZ1) and Public Conservation and Resource Zone (PCRZ). Zoning sets what you can build and do on a site, and can differ lot by lot.

Narracan has 11 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 325 surveyed parcels in Narracan, the median lot size is about 18,389 m². There are also 122 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 Narracan had 262 usual residents, with a median age of 48 and an average household size of 2.4 people. The wider Trafalgar (Vic.) statistical area, which contains Narracan, went from 6,112 people in 2001 to 8,618 in 2025, up 41%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Narracan alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Narracan scores 980 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.
