Sorrento flood map & planning overlays

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

Flood mapping covers Sorrento and none of the suburb falls within a mapped flood overlay (the council-wide suburb average is 3%). Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.

Around 100% of Sorrento is mapped as bushfire-prone, compared with a Mornington Peninsula average of 89%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

The dominant planning zone in Sorrento is General Residential Zone (GRZ1), though the suburb also includes Public Conservation and Resource Zone (PCRZ) and Special Use Zone (SUZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.

Sorrento has 99 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 3,988 surveyed parcels in Sorrento, the median lot size is about 870 m². There are also 703 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 Sorrento itself. The suburb is served by 43 bus stops.

At the 2021 Census Sorrento had 2,013 usual residents, with a median age of 64 and an average household size of 2.0 people. The wider Point Nepean statistical area, which contains Sorrento, went from 15,820 people in 2001 to 20,574 in 2025, up 30%. ABS publishes no annual population series for individual suburbs, so that trend describes the surrounding area rather than Sorrento alone.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Sorrento scores 1099 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 Sorrento was $1,658 a week at the 2021 Census, against $1,906 for the typical suburb in Mornington Peninsula. Median rent was $462 a week and the median mortgage repayment $2,167 a month. These are 2021 Census figures and have not been indexed to today.

A Sorrento 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.
