How it compares

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. 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. Not yet assessed: the Code applies its precautionary Regional or Outback bushfire overlay to most of this suburb. 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.
