Clematis flood map & planning overlays

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

Flood mapping covers Clematis and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 42%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Clematis 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 Clematis is Rural Conservation Zone (RCZ2), though the suburb also includes Low Density Residential Zone (LDRZ2) and Transport Zone (TRZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.

No heritage-listed places are on record within Clematis. Even so, it is worth confirming for an individual property before any works.

Across 172 surveyed parcels in Clematis, the median lot size is about 2,007 m². There are also 110 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.

There is no train station inside Clematis itself. The suburb is served by 5 bus stops.

At the 2021 Census Clematis had 352 usual residents, with a median age of 39 and an average household size of 2.8 people. The wider Emerald - Cockatoo statistical area, which contains Clematis, went from 16,964 people in 2001 to 19,043 in 2025, up 12%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Clematis alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Clematis scores 1032 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 Clematis was $2,288 a week at the 2021 Census, against $1,976 for the typical suburb in Cardinia. Median rent was $372 a week and the median mortgage repayment $2,000 a month. These are 2021 Census figures and have not been indexed to today.

A Clematis 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.
