How it compares
Household income / wk10th percentile
<$564ABS Census 2021$3,833+
Percentiles rank this suburb against New South Wales suburbs that carry the metric — never across states, and never against suburbs where it is missing. Price references are ABS median established-house transfer prices for the Mar 2026 quarter (CC BY 4.0); the suburb figure is a Valuer-General median over a different window, so read the gap as indicative. Income references are the Census 2021 median of the middle suburb in New South Wales and nationally, not a household-weighted median.

Shares are the proportion of the suburb's land area; where part of a suburb is unmapped, only its mapped land counts, so the share is a floor. Land where Landsat saw water in at least 1% of clear passes since 1987, excluding permanent water and filtered by DEA's confidence layer. Satellites miss flood peaks, so this is a floor, not a risk estimate; dense high-rise cores can still register tower shadow as water. A statutory planning-control boundary, not a flood extent, and it can lag the latest flood study. Only the councils that lodged a flood map in their planning instrument are covered; everywhere else is shown as no statutory layer, not as 0%. NSW councils have owned flood-map currency since July 2021, so the state layer may be older than a council's own study. Designated for development control; a designation, not a prediction of fire behaviour. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.

Planning instrument: Hornsby Local Environmental Plan 2013. Zones are grouped into ten families so states compare; the council's own scheme is the authority for any one lot. Listed-place counts follow each state's own list, so they do not compare across states. Source: NSW EPI Land Zoning; NSW EPI Heritage.
