Percentiles rank this suburb against South Australia 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 South Australia 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. Not yet assessed: the Code applies its precautionary Evidence Required overlay to most of this suburb. Designated for development control; a designation, not a prediction of fire behaviour. Covers the Code's High, Medium, General and Urban Interface bushfire overlays. Land under its precautionary Regional and Outback overlays has not been assessed and is shown as no statutory layer. Elevation is orthometric height from a 30 m model; no hydrology or drainage is modelled.

Planning instrument: Planning and Design Code. 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: SA Planning and Design Code zones; SA Code heritage & character overlays.
